Metcom Audio Controller

1. Introduction The Metcom controller is a 19” rack mounted component of a Metcom Aviation

Meteorological system. Its function is to:

Convert the audio signals generated by the Metcom server(s) to provide balanced

outputs to third party ATIS radio systems.

Where two servers are used the controller can switch between signals output from

a primary server to those from a secondary, failover server when it gets a command

to do so from that server.

The controller also has voltage free contacts which close as a “Press to talk” (PTT)

signal for the radio systems. This function is controlled by the active server.

The controller can also provide signals and control to an optional, external

telephone interface, to allow user to dial in and listen to the ATIS messages.

The controller has a small loudspeaker and selector switch on its front panel to

allow a local check of any broadcast channels. It allows checking of the channels

coming from the two servers and also the channels being output from the system.

2. Quick Start Instructions The controller will normally be installed by trained personnel. These quick start

instructions give a guide to basic operation of the system. Further details on the

function and wiring of the system and fault finding are given in later sections of the

manual.

If the system has previously been fully switched off it may be necessary to turn the

controller on using the power switch on the read panel. The switch is located next to

the mains power connector. When powered on the power LED on the front panel

should illuminate which indicates the internal power supplies are powered on.

The system will then power up and become active within one minute. By default the

“PRIMARY” LED on the front panel will switch on and any audio feeds will be

switched to those from the primary server. The system will stay in this state up until

the point that messages are sent from a server to switch to the secondary server audio

feeds, which will be indicated by the “SECONDARY” LED illuminating.

Once the servers are up and running and audio ATIS messages are received they will

be routed to the relevant outputs. Both the inputs and outputs of the systems can be

monitored using the speaker on the front panel of the system. Simply turn up the

volume by rotating the lower knob with the volume symbol clockwise (“ ”) and

change the audio channel switch to select the channel to be monitored. When

finished, rotate the volume knob fully anti-clockwise to silence the speaker.

Please note that on boot-up the Metcom system will not normally output any ATIS

messages immediately on power-up. You will either need to wait for a scheduled

METAR message to be broadcast or set a test ATIS message to be broadcast to test

the system. Please take caution when doing this on a live system to avoid test

messages being broadcast more widely.

Instructions using the optional telephone line interface are given in other manuals.

3. A functional description of the controller The controller is housed in a metal, screened and earthed 2U 19” case. The front

panel of the unit have labelled LED indicators to show that controller is powered and

which server is currently active, i.e. the primary or secondary server.

Figure 1: The Metcom Controller front panel.

There are two knobs on the left hand side which allow you to select which of 12

possible audio channels, listed on the panel, can be monitored via the small

loudspeaker mounted in the centre of the panel. A volume control (the lower knob)

controls the volume of the loudspeaker.

The rear panel of the speaker has an AC power input in the form on an IEC320 socket

that has a switch and fuse built in.

Figure 2: The Metcom Controller rear panel.

The audio signals from the two Metcom servers are fed into the controller via 3.5 mm

audio jacks, labelled ATIS AUDIO INPUTS. Separate arrival and departure feeds are

sent from each server. Each feed has a standard ATIS output and one for broadcast

by telephone (the content of the two feeds are different). The audio signals are

switched, by internal relays, to the main output sockets (XLR connectors) labelled

ATIS AUDIO OUTPUTS. There are outputs for connection to ATIS radios and an

optional telephone interface (labelled “TEL”).

On the rear panel there is a 15-way D connector for connection of press to talk (PTT)

and control outputs and a connection to the optional telephone interface (TEL).

Connection details are given below. Next to the AC power socket is an Ethernet LAN

connection for connection to the Metcom LAN network.

User Manual

Internally there is an industry standard, digital I/O module which is controlled by the

active Metcom server via the Ethernet connection. That module controls the relays

which switch the audio signals and generates the PTT and other control signals.

4. Specifications Mains input power requirements:

Voltage range: 15 – 230 VAC (nominal), 93 – 264 VAC (working range)

Frequency range: 50/60 Hz nominal, 47-63 Hz (working range)

Power use: <15W

Fuse rating: 2A slow blow.

Audio input and output signals:

The controller will switch and monitor any level of signal output by the Metcom

Server sound cards. Outputs are isolated from the inputs by a 600 ohm audio

transformer (OEP Z1604). The outputs are available as a balanced or single-ended

(ground referenced) output on the XLR connectors. Only balanced outputs are

available on the ¼” jack sockets.

Audio outputs are protected by 1500W, 22V clamp diodes (Transzorbs).

PTT outputs are isolated relay contacts rated at:

220V DC/AC

Maximum 2A, 60W DC switching.

Isolation 1.5 KV AC

Electrical life:100 million operations typical.

Telephone line interface:

Compatible with the Soniflex HY03 analogue line interface.

The Metcom controller limits call length to 270 sec (nominal).

5. Basic fault finding Gross failure of the unit would normally be dealt with by a service engineer who will

normally swap out the entire controller which will be returned to base for repair.

Prior to doing this please review some of the simpler possible faults and likely

solutions:

Metcom Audio Controller

4

Fault: the power LED does not light on the front panel

Check the mains feed to the rack is live and the connection of AC power to the IEC

socket at the back of the controller.

Check the fuse in the mains plug and also in the IEC socket on the back of the unit.

If either have blown only replace the fuses with caution as failure of the fuse may

indicate a more serious internal fault.

Also check the mains switch built into the IEC power socket is switched on and the

switch illuminated. If this switch is illuminated and the LED indicator on the front

panel is not illuminated this indicated a fault with the internal power supply.

Fault: the LED on the front panel does not match the current active server

This is likely to indicate a problem in communication between the servers and the

Metcom Controller, so the Ethernet network connections and server between the

servers and the controller should be checked, making sure any switches between

the two are powered and running correctly.

It is also possible the internal digital control module has locked up or failed. This

should be reported as a potential fault but recovery could be attempted by turning

the mains power off to the controller, waiting 2 minutes and applying power to

force a hard reset off the module. Service personnel can also check the function of

the module and its settings following the procedure in Appendix B of this manual.

Fault: no ATIS messages can be heard on the loudspeaker on the front panel

First check the volume level is set high enough and the correct channel is selected.

Then check on one of the active Metcom consoles that Metcom is running

correctly and ATIS messages have been entered for transmission (a freshly booted

server will not output messages).

Check the input connections at the rear of the panel to make sure that the cables

between the servers’ audio output devices and the audio inputs are plugged in

correctly and no leads have worked lose.

Check the connection between the audio output device and server (usually a USB

connection) is plugged in correctly.

Also check the network connections between the Metcom controller and servers as

loss of connection could prevent correct switchover and then no output from the

system, in the event of a failed primary server.

If messages can be heard on the inputs but not be heard on the output channels also

check the output cables are correctly connected as the output can be affected by

shorts or noise coming in from the cabling and devices to which they are

connected.

Fault: monitored ATIS messages are wrongly formed or are on the wrong

channel

The controller does not define the messages being sent, please refer to the Metcom

console to check which messages a programmed for transmission.

If the fault is as simple as the wrong message is being transmitted on the wrong

channel, e.g. arrivals and departure messages are swapped as well as checking the

Metcom controller check the routing of the audio cables from the servers to the

Metcom controller to make sure they have not been inadvertently swapped.

User Manual

Fault: the monitored signals are distorted

If the fault is only heard on the monitoring speaker and not on the public

broadcasts check the volume control on the front panel is not set too high.

If the fault is only heard on the public broadcasts check the connections to the

relevant device making sure no output connections have worked loose or cables

damaged.

Check the cabling at the rear of the box between the server audio outputs and

controller to ensure the cables are fully plugged in.

Appendix B. Setting up or reconfiguring the digital control module

The internal control module is preconfigured by Campbell Scientific. This

information is provided to allow a module to be reconfigured or a new module

setup as a replacement. Reconfiguration will normally only be required if the

module is replaced with a new, unconfigured unit.

1. Obtain and install the Adam.Apax .NET utility, which can be downloaded

from here:

http://support.advantech.com/support/DownloadSRDetail_New.aspx?SR_ID=

1-2AKUDB&Doc_Source=Download You also need to obtain a copy of the

recommended firmware from Campbell Scientific.

2. Connect mains to the Metcom Controller and check the power and primary

LED’s illuminate.

3. After factory configuration the module address of the ADAM digital module

inside the Metcom Controller is set to 172.16.1.10. However a new module

has the address 10.0.0.1. To change the setting in the module a laptop needs to

be set up in the same subnet range. The instructions below assume you are

setting up a new module. First set the PC to an IP address with a subnet

address to match the module and an IP address which is not the same of the

module, as the screen shot below shows:

Appendix B. Setting up or reconfiguring the digital control module
