NRAO 45-FT REMOTE CONTROL DATA LINK SYSTEM

Introduction

General information is presented as an aid in troubleshooting the digital

and analog telescope control and monitoring data signaling system linking the

interferometer control building and the 45-ft remote site. The data link com-

prises 2 modules, one each at the control building and 45-ft remote site. Each

module comprises a data concentrator and data distributor operating in full du-

plex via a microwave link described in EDIR #126. We like to think of all sig-

nals transmitted from the control building to the remote site as up-link signals

and all others as down-link signals. In general, control signals are up-link

signals while monitor or status signals are down-link signals. Specific control

signals adjust the radiometers, focus and rotation of the feeds, telescope posi-

tion, and power circuits. There are specific status signals generated that moni-

tor almost any condition regarding the telescope and remote site. The telescope

position control and readout system is described in EDIR #127 and EDIR #149.

The remote site weather station is described in EDIR #151. The remote site pri-

mary power monitor is described in EDIR #135. The telescope position stand-

alone control is described in EDIR #128.

All control and monitor data handled by the system may be inspected via

numeric data displays.

The data displays comprise two groups of hardware located in the data link

front panel. Each consist of one 16-bit binary display, one 7-digit octal/deci-

mal display, and one 3-digit data access control thumbwheel.

RINARY WORD

In general, all data handled by the data link is viewable by selection of a

proper access code. A data word comprises 16 bits which is displayed in the bi-

nary display in the same form as it is presented to the DDP-116 computer "A-

Register". Also, for some access codes, the data is presented in "useful format"

for humans on the 7-digit octal/decimal numerical display. One has to be aware

of only one restriction required by the system logic which is that a currently

valid access code must be dialed up on both data access control thumbwheels since

the display system will "lock up" waiting for the invalid access code that never

arrives in the data stream. Codes below 40.0 will capture data from the up link

data stream while codes 40.0 and above capture down link data.

Troubleshooting Aids

The following is presented as an aid to clearing faults. Only notes are

provided on schematics and occasional comments provided herein since a thorough

description of every nut and bolt is not possible due to space limitations. In

general, the schematics are organized according to the electronics associated

with each circuit card which is identified by numbered tags running from 1-22.

Also, each tag contains legends defining the function of each card. Generally,

the transmitter electronic cards are on the left behind the front door, while

the receiver cards are on the right.

TRANSMITTER MODULATOR a SYSTEM TIMING CARD 1

"NRZ" data from the shift registers sprinkled down the other transmitter cards is

introduced at Pin 10 with the clock at Pin M. A ninth bit for parity is inserted

serially for each eight NRZ data bits under control of flip-flop K. Parity is

generated by chip D and monitored at Pin L.

- 12 -

The row of flip-flops along the bottom of the schematic sequentially control

the transmitter status. The sequence is triggered by the assured trigger "fly-

wheel" circuit which runs synchronously with the 0.1 sec sidereal introduced at

Pin Y. A scope may be used to monitor the bi-phase encoded data output at Pin 8

by synching at Pin H. Pin H is high during the data transmit sequence. The

transmitter operates in an assynchronous mode in which the receiver is resynch-

ronized every 0.1 sec at the start of the data sequence when 32 logic ones is

transmitted. Data is loaded into the shift registers next, then data is trans-

mitted with parity added, then a postamble for error checking of 24 ones and

finally a zero sequence, for maintaining bit sync, lasting until the next trigger.

RECEIVER DEMODULATOR 81 SYSTEM TIMING CARD 2

Optically-isolated 5 kilo-bit/sec bi-phase SO data is introduced at Pin 8.

- 14 -

"NRZ" data issues at pin 10. Scope sync may be obtained at pin 11 which is con-

nected to the trigger input pin 4 of transmitter card 1 at the 45-ft site to

synchronize the down-link transmitted sequence to the up-link sequence so that

the DDP-116 computer may reliably read the monitordata at the same time as the

control data is updated under control of one priority interrupt that occurs every

0.1 second sidereal. Every ninth bit of data is extracted as parity and verified

under control of flip-flop X. Parity is checked only during the active data se-

quence under control of flip-flop S. An assured clock digital "flywheel" cir-

cuit maintains bit sync during drop outs and noisy conditions.

- 15 -

Card #3

Five different error checks are performed on received data under control of

card #3:

1. No sync -- No preamble received.

2. Double sync -- No postamble received between preambles.

3. Parity -- Serial parity in groups of eight bits is checkedduring data sequence.

4. Distributed data -- Four groups of 3 bits each that occurduring the analog data words are compared.

5. Frame length -- Check number of bits occurring between pre-amble and postamble.

When any errors occur the error averager circuit maintains a tally. If the

tally exceeds a certain percentage according to the relation:

Receiver System . 100%

Tolerable Error 1 + 2(A-B)

where "A" and "B" are values set in thumbwheels that control the "good" versus

"bad" frame weighted values.

The receiver response time to "good" or "bad" data is:

RECEIVER SINGLE BIT CONTROLS CARD 5

-19-

(74174) under control of card #3. The double-throw switches (8266) connect either

the latches or the hand-wired program plugs to optical isolators which isolate the

outputs from the various systems connected to the data link. The double-throw

switches are toggled under control of the receiver error control logic of card #3.

When the receiver detects a percentage of transmission errors that exceeds that

value selected by the thumbwheels A and B, then the receiver goes into a "wait"

mode wherein the output circuits are connected to the "hand-wire" program defined

by the plugs. When the errors fall below the critical level the receiver will

return to the receive mode, thus toggling the double-throw switches each to the

latch output circuits. Also, during the receive condition but during a data frame

detected as in error, the latches (74714) are not updated, but retain the old

data from the previous "good" frame. This sequence is under control of card #3.

Card #7

The receiver LST/Az/E1 display driver card #7 is a general purpose cardthat is designed to capture from the serial data stream any two 16-bit wordsas selected by pins N, P, R, S, T, and W and send the data in 4-bit BCD char-acter serial format to either the seven digit LST displays at the 45-ft site ora pair of four digit azimuth and elevation coarse position displays at the con-trol building control panel. The schematic is shown below.

The word and bit counter signals from the receiver card #2 are connectedto the word and bit counter inputs of card #7 which are used as an index forthe data capture sequence.

Every 0.1 second, the computer receives an interrupt signaling the computer

to output five 16-bit words to the data link. As each OTA is executed, the data

on the output buss is latched into the corresponding concentrator shift register

WD-1, through WD-5. After the OTA sequence, WD-1 and WD-2 contain the azimuth

position command, WD-3 and WD-4 contain the elevation position command, and WD-5

contains the focus/polarization command, if any. The data in chip HH is strobed

at the start of the next transmitter concentrator load sequence so that it con-

tains the receiver error status. The OTA sequence counter (chip R) is reset with

the PIL and advanced with the address gated RRL so that through the 8250 the

shift registers are sequencially loaded with each successive OTA.

The WD-1 shift register (chips PP and NN) unloads the data to the computer when

an INA 007 instruction is executed. After the first INA after an interrupt on

line 40, the data is shifted (16 bits for each INA) from the rest of the data dis-

tributer shift registers on other receiver cards at the data link control building

(DLCB) terminal. Thus, the computer may unload and read all monitor data sent

from the remote site after it has been latched for utilization by the various sub-

systems. Also card 11 comprises some data regarding the remote site receiver

status.

Card #12

The circuits of card #12 is the computer interface control logic that works

in conjunction with cards 11 and 8 to provide proper computer I/O sequence.

RECEIVER COMPUTER INTERFACE CONTROL CARD 12

- 28-

Normally, the data is shifted into the data distributor shift registers at

a 5 kilobit per second rate. After a complete frame is received, the data is

latched into the output register latches if the frame checks good by the circuits

of card 3. Then a PIL is issued. If the data frame contains transmission errors,

then no PIL is issued until the assured PIL one shots time out at which time a

PIL is forced so that the computer may "OTA" the next telescope position control

words to the transmitter. No computer INA's are possible if a bad data frame

occurs.

The combined S.R. clock signal at pin 9 is connected to the distributor

shift register clock which is normally a 5 kHz clock during the receive sequence.

After a computer INA pin 9 output is a 1.28 MHz clock signal for 16 pulses which

unloads another 16-bit word from the WD-2 shift register to the WD-1 shift register

on card 11.

TRANSMITTER ANALOG DATA Al CARD 14

The ADC converts 4 channels in less than 100 milliseconds.

- 31-

Card #15

When card 15 is used, the last 3 channels of card 14 are multiplexed, yield-ing 15 analog channels and 1 precision channel that is left unaffected for a totalof 16 channels. During each 100 millisecond data frame 4 conversions are done,yielding one precision channel and 3 multiplexed channels. A sequence of five 100millisecond sequences is required to provide data for all 16 channels. The preci-sion channel is converted 5 times for each single conversion of the other 15.

The circuits on the left are the data distributor shift register and latch cir-

cuits providing 4 digital to analog data circuits. The 13-pole 4-position switch

on the right selects which word is converted during a given time.

A sequence of 4 conversions are done in 100 milliseconds. The control coun-

ter circuit for the switch is in the lower-middle of the drawing. The upper mid-

dle shows the distributed data error test circuit which compares the four 3-bit

I.D. groups which should be identical within a given data frame.

These circuits control the front panel digital displays. Data is captured

and converted as necessary to provide serial data and clock to the binary dis-

plays and character serial data to the decimal displays under control of the

access code thumbwheel switches on the front panel.

RECEIVER FRONT PANEL DISPLAYS CONTROL CARD 20

- 38-

Data transmitted over the data link system is sent to the binary displays

unchanged while the data is formatted to "human" terms and sent to the decimal

displays. Since we have two sets of binary and decimal displays, all of the

logic is "time shared" so that data is alternated and sent to the respective dis-

play by alternate control of the respective data access thumbwheel. The data is

brought into the shift registers (8570) in the upper left corner of the drawing.

Data is sent through the 26-pole 4-position switch in the upper-right quadrant

and returned to the output shift registers (8590) on the left. When position "B"

of the switch is selected, binary data is sent to the binary-to-decimal converter

in the lower left corner for conversion.

Card #21

The electronics of card 21 as shown on the next page comprises a data input

buss, upper left corner (which is connected to the position encoders); a data

concentrator shift register, upper middle; azimuth binary-to-decimal degrees con-

verter, upper right; elevation converter, lower left; and remote site control

panel local position readout displays driver circuit. the azimuth converter isbasically a digital count-down circuit that inhibits a clock pulse to the decimal

counter (8280) for every eight clocks to the binary counter (8563) under control

of gate "Z"; except for every 32nd group of eight binary clock pulses the decimal

clock is allowed to pass under control of gate T. A conversion sequence is trig-gered every 0.1 second by the data concentrator shift register load pulse from

the transmitter card #1 via pin #5. the elevation converter (lower left) operates

in similar fashion to the azimuth converter. The converted data is transferred

out of the converter at the same instant that new binary data is loaded. The

circuit in the lower right drives the pair of 4-digit control panel displays.

Converted data is received from the serial output to chip "PP" via "RR" and trans-

lated to 4-bit character serial format by chip "D" and sent to the display modules.

The address counters "K" and "L" select the digit receiving the present

character. The data strobe provided by gate "E-6" is retimed by one shot chip

"F" and sent to the display via the RLC 25 kHz low pass filter network which im-

proves noise immunity over the display cable.

RECEIVER FOCUS/ROTATION RATE CONTROL CARD 22

The circuit accepts a binary command input via the 16-bit data distributor

chips "NN" and "LL" which is latched by chips "PP", "MM", and "KK" and sent to

the digital low pass filter circuit comprising the comparator circuit "JJ" and

"HH" which controls the up i down counters (8563) via gates "T", "U", and "M".

The output of the counter is fed back to the other input of the comparator. The

feed-back loop operates in such a way that the counter output drives up or down

until it equals the binary input command. This operation limits the rate of

change in velocity command to the focus or rotation step motors. This rate of

- 41 -

change is controlled by the clock input to the up/down counter at pin "V-3".

The output of the up/down counter is also connected to the rate multiplier

chips "AA" and "BB" which function as a frequency synthesizer that drives the

step motor translator drivers via the focus/rotation function and direction se-

lection logic in the upper right corner of the drawing. The function and direc-

tion are selected by control bits from the distributor. In actual operation, if

the system is being commanded to run in one direction and function and the direc-

tion and/or function is changed, then the system will first go to zero rate under

control of logic "J", "K", and "U" and then the new command will be executed.

Wire Lists and Cable Lists

The following compressed wire and cable lists are presented as an aid to

troubleshooting and understanding the system. The control building terminal is

designated as "Data Link Control Building" (DLCB) whereas the 45-ft remote termi-

nal is designated as the "Data Link 45 Foot" (DL45'). All cable connectors are

"J" numbers and card slots are "S" numbers.
