YEah you have to use a null-modem cable to be able to talk to your device via RS232

If the checksum and setup are rights,
did you try to cross the serial to Moxa cable ?
Hope this helps

We're trying to control a Gamma ion multi-pump controller via ethernet from a soft ioc. The problem is that we can't get any response from the controller. We're using a stream device protocol file that previous worked for an RS232 gamma ion pump controller. Although I have also not been able to get any response by telnetting directly to the port and attempting to issue commands.
This device uses a checksum, so the problem could be that the checksum is incorrect or some other problem such as the configuration of the MOXA serial to ethernet card that's internal to the device. It appears that I've configured the bit rate, parity, and stop bits to match the devices settings. What else should I be checking? perhaps the response is just not being transmitted over ethernet and I should configure data packing? or something else.
