Troubleshooting the Communications Link
If a problem occurs in establishing a communications link between the PC and the 509ITM,
check the following:
• Is the cable a straight-through cable (not a null) and is it securely connected to the PC
and the 509ITM?
• Is the 509ITM energized?
• Is the cable connected to the same COM port displayed in the Desktop
Communications?
• Does the 509ITM device address match the selection in the Desktop
Communications Address field?
• Does the 509ITM service port baud rate match the baud rate in the Desktop
Communications? The default baud rate is 19,200 baud
.
Important:
If the ITM509 service port was reconfigured to another baud rate, the Desktop
Communications baud rate must match the new configuration.
