The following specifications describe the standard (as opposed to optional) inputs and outputs on the 
standard configuration of the XLi.

The standard serial data port is a bi-directional EIA standard RS-232C interface. The serial data port is 
configured via the Keypad / Display and Standard network port. 

Parity - NONE is only available/valid when Data Bits is set to 8.

The Ethernet port interface has a standard RJ-45 connector that provides IEEE 802.3 frame 10/100 
Base-T Ethernet.
