Hello, I’m having trouble using StreamDevice to communicate with a TDK Lambda Genesys 30-110 power supply that’s talking to a Moxa NPort 6000 Series terminal server. We are running the same asyn code on another model, the Genesys 50-200, but it
has no issue talking to a Moxa or a Digi. When my IOC sends “ADR 06” to the 30-110 all at once, the power supply returns “C01” (illegal command or query), but when I enter the same command manually using telnet, I get “OK” as expected. I also get “OK” if I use asynInterposeDelay
and a slow scan rate. However, when my IOC sends this command as one string to a Digi terminal server, I also get “OK”. Is there any reason why I need to use asynInterposeDelay when using one terminal server but not for another? We have a network person looking at the configuration of the terminal servers, but the basic web interface parameters are quite similar. In the meantime, do you have any suggestions?
