2. Interfacing Protocol
2.1. RS-232 Operation
2.1.1. DIP Switch Settings and Pin Signals
The 9XTend RS-232/485 RF Modem supports the following interfacing protocols:
Table 2‐01. RS‐232 Signals and their implementations on the XTend RF Modem
* The ‘Pin Reference Name’ provides an associative tag that references commands used to define pin behaviors.
GPI stands for ʺGeneral Purpose Inputʺ and GPO stands for ʺGeneral Purpose Outputʺ. As an example, the CD
command is used to define the behavior of GPO2 (DB‐9 pin number 1). The ‘Pin Reference Name’ is the name
used when referring to XTend commands and parameters.

DIP Switch settings are read and applied
only while powering‐on.
