RS-485/422 (DTE) Serial Port
The cRIO-9035 has an RS-485/422 (DTE) serial port that is implemented with an RJ-50, 10-
position modular jack. The RJ-50 connector is isolated from the cRIO-9035. For more
information about the electrical isolation of the RS-485/422 (DTE) port, refer to the
specifications on

The following accessory is available to connect the RS-485/422 (DTE) serial port to a 9-pin
DSUB plug.
Caution
To ensure the specified EMC performance, you must use an isolated cable
with the RS-485/422 (DTE) serial port. The following accessory meets this
requirement.
