With firmware version 3.3 and earlier, SD commands must be sent with a comma before the
terminator.
Troubleshooting
In the case where the driver is not working, you can always troubleshoot with HyperTerminal.
Using TeraTerm or HyperTerm, you can send commands to the serial port and see the
responses coming back. Connect to the system controller's serial port using terminal program
of choice. Press Ctrl + j to send an LF character and the controller should respond with an
E
indicating that the command was in error since there was no actual command.
Using the checksumcalc.exe program, enter a command in the command box. Press Calc
Checksum, and press Copy to Clipboard. Switch to terminal program and paste the
command, and press . This will only work if you have the terminal program set to send
a CR LF pair when enter is pressed. If this is not the case, then you can press Ctrl + m and then
Ctrl + j to send the CR LF pair.
Notes
• The Pesa USP driver supports Matrix Controller firmware version 3.3 and
earlier.
• Every physical router destination label defined in XEdit must match a
destination label specified in the Pesa router’s configuration.
• This driver does not support checksums. To turn off the checksum, open
PERC2000 (version 2.1), click System Parameters, and then set the checksum
options to NONE for every port.
• If your Pesa router has an older controller card that was upgraded to the
PERC2000 software, the USP filtering could be enabled even if the
configuration file indicates that it is not. If you notice that UMD statuses do
not reflect crosspoint changes immediately, try enabling all filtering on the
router, and then disabling all filtering. In some cases enabling filtering of all
unsolicited status from the router will be necessary.
• Miranda’s Router Control Software cannot communicate with the router
when RTS-CTS flow control is enabled.
• In the 3500+ series controller for the Pesa router, RTS-CTS is enabled at the
hardware level and cannot be disabled. In the case of PERC2000 controllers,
flow control is optional and configured in the PERC2000 Software.
• Level or Frame ID designation in Router Manager or XEdit must be set to 1
when controlling a single Pesa router. Increment by 1 if there are multiple
routers to be configured.
• You must use RS-232 communication to communicate to the router.
• In some instances, after a reboot of the router or the KX/iControl, the
mnemonics will not update on the KX/iControl display automatically. Making
a crosspoint change to the router will cause an update to occur.
