Using PComm
The PComm Diagnostic program is a very useful tool for checking the status of MOXA’s
multiport boards. It provides internal and external testing of IRQ, TxD/RxD, UART,
CTS/RTS, DTR/DSR, etc. This program can be used to make sure that MOXA’s boards
and ports are working properly.
To start this program, click on Start " Programs " PComm Lite 2000 " PComm
Diagnostic .
NOTE: If you do not have the PComm software, you can download the free version from
Moxa’s website at www.moxa.com.
