There are two types of RS232 serial devices: '''DTE''' and '''DCE'''. DTE typically refers to the serial port on a PC or terminal, while DCE refers to communication devices. Connectors mounted on DTE are likely to be male, and those mounted on DCE are likely to be female.

To connect another DCE device to RUT955, a Null-modem (crossed) Male/Male cable should be used:

Maximum cable length is 15 meters or the cable length equal to a capacitance of 2500 pF (for a 19200 baud rate). Using lower capacitance cables can increase the distance. Reducing communication speed can also increase maximum cable length.
