TX4A::>_
As can be seen from the above example the repeat command refreshed the status of
SILBUS channel D1 on a new line every five seconds. In the LF mode a record of the
status of D1 can be viewed on the screen.
6.4 VERSION COMMAND
The VERSION command is used to display the serial number, abbreviated type number,
software version and program memory checksum of the TX4A. The command can be
invoked as shown in the following example:
TX4A::>VER
SN:09124321 TX4A 1V01 0XB12F
TX4A::>_
This command is useful when the user needs to know the software version or serial
number. The program memory checksum is useful to confirm that a software update has
completed successfully without any programming errors.
6.5 STACK COMMAND
The STACK command is provided to allow the technician to gauge the health of the TX4A
microprocessor and its code by displaying the maximum usage of the program stack. The
display is a peak value of the stack usage since the TX4A was powered up. The
command can be invoked as shown in the example below:
TX4A::>STACK
Stack usage/size = 312/1024
Percentage Used = 30%
TX4A::>_
This command would typically only be used when requested by an Austdac software
engineer.
6.6 SILBUS MAP COMMAND
The SILBUS map command allows the operator to obtain a snapshot of the SILBUS
network to which the transmitter is connected. The map shows all of the SILBUS channels
available on the network. The map consists of a table with a heading of groups below
which is displayed the channels using ones and zeros. Each group is shown vertically with
1 at the top and 8 at the bottom. A one indicates an ON channel and a zero indicates an
