==RS232 connector pinout==
The RS232 connector type on this device is a '''DCE female'''. DCE stands for Data Communication Equipment.

==Cables==
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.
RUT955 is DCE and has a female connector.
----
To connect a standard DTE device to RUT955, use a straight-through Female/Male RS232 cable:

See straight cable pinout below:

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

See straight crossed cable pinout below:

----
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.
