Solution
No, the cDAQ-9188 does not support RS-232 or RS-485 serial communications on the chassis itself, or through a C Series module.
In order to use serial communications with NI cDAQ you will need one of the following:
- (RS-232 only) A cDAQ-913x controller, such as the cDAQ-9137 have a RS-232 port on the device.
- An NI CompactRIO(cRIO) controller.
- cRIO controllers are compatible with the NI-9870, which is a module designed for RS-232 communication. They are also compatible with the NI-9871 which supports RS-232 and RS-485.
