FirmwareNormally firmware updating is performed in Receiver Managing
mode. However, if a receiver becomes inoperative, e.g., the previous
receiver firmware updating was not successful; only the Simple
Terminal mode will be available for use.
The firmware updating process in Simple Terminal mode is similar to
that described in Chapter 4, “Receiver Managing” on page 4-1. Thereis only one difference: when in Simple Terminal mode, only the
Power ON capture method is available.
GRX Utility allows uploading firmware files to the GRX receiver
(GMSX board), internal modem and power board.
NOTICE
Port settings depend on the OS. Usually the OS for
the PC remembers the previous port state, so if the
port baud rate was changed, the assigned value willbe kept. CE.NET and Windows Mobile will usually
reset port settings by default. I.e., the next time you
open a serial port, you should adjust port settings
again.

This dialog allows you to upload firmware files to the receiver that is
connected to the controller and has the following parameters:
NOTICE
Do not update GRX1 firmware when using a
Bluetooth connection of external GRX1 receiver
with the integrated controller. Sokkia recommends
for firmware uploads to connect to the receiver via
included serial cable. Resetting the Receiver may
break the Bluetooth connection and interrupt the
firmware uploading process; as a result of this
interruption, the receiver may become inoperative.
NOTICE
Be extremely attentive when selecting firmware
updating parameters, especially when updating
modem firmware. Some modem models don’t
allow terminating of the firmware updating process.
So if you choose incorrect parameter combinations,
or interrupt the firmware updating process, it maydamage your equipment. If this happens, and you
cannot update firmware using even the Power On
capture, you will need to have the hardware
serviced.

Tools
The Tools icon opens the Send Command dialog box that allows you
to reset the receiver and to clear the NVRAM.
Figure 4-11. Send Command
• Reset Receiver – leaves all files intact. Resetting the receiver is
similar to a hot resetting of the computer, but without goingthrough a power cycle.
After a receiver reset operation, the receiver requires a few
seconds to a few minutes to begin tracking satellites and logging
data.
• Clear NVRAM – this command will not delete any files from the
receiver memory. It will reset the receiver parameters to factory
default values (such as active antenna input, elevation mask and
recording interval, and information about the receiver’s internal
file system).
After clearing the NVRAM, the receiver will require some time
to collect new ephemerides and almanacs (around 15 minutes).
Clearing the NVRAM can be interpreted as a “cold reset” of your
computer.

– Period : specifies the message output interval. If set to zero,
the corresponding message will be output at the highest
possible rate.
– Phase: specifies a time shift in the output of a message with
respect to the moment when the receiver time is a multiple of
the specified period.
– Count : serves two purposes. Firstly, if set to a positive
number, specifies how many times the message outputs. Zero
means an unlimited number of times the message outputs.
Secondly, if set to a negative number, instructs the receiver to
encapsulate a message into >> message before output.
– Flags: provide further adjustment of the way the message is
output. Table 4-7 briefly explains the flags. For details, refer
to the GRIL Reference Manual.

Flag Description
Out If the flag is selected, the first of the messages invoked by the
corresponding command will be output at the epoch closest to the
command execution time (whatever the specified "period" option).
Change If the flag is selected, the corresponding message will be output
only if the message data have changed.
Out On Add If this flag is set, then the (first) message will be output immediately
after executing the corresponding em or out command.
Notena The receiver uses this flag in order not to output the file header
