Using BL2100. Attempting to communicate with a HART-enabled sensor system through a HART-RS232 modem (converter manufactured by Raytek). Sensor is not responding. I am sure that the sensors works since when the HART-RS232 is used in conjunction with the configuration software that came with the sensor, the sensor responds. However, when I connect the HART-RS232 back to the BL2100, somehow, SerXputs does not work. I looked at a few code examples for Dynamic C, and I saw a command "SerMode(0)" which I could not find a reference on any documentation I have on hand. I think I may be missing some critical communication setting and perhaps I should be setting "Serial Mode" as another type (i.e., not "0"). Need help on this. Willing to engage a consultant to get this done. Please contact me (+1.281.844.2275 Victor, Houston USA) or e-mail me (email@example.com) your contact number so I can call. Thanks.
