Overview
of
the
900HP
RF
Modem
The XBee-PRO 900HP RF Modem is a small, low-power solution that uses the XBee-
PRO 900HP 900 MHz RF Module in an enclosure to communicate with systems using
RS-232, RS-485, and USB interfaces. It allows you to easily make your existing wired
systems wireless simply by connecting to this product.
When a system is connected to the XBee-PRO 900HP RF Modem, it can transmit and
receive data from multiple radios on the same wireless network. This is achieved by
using Digi’s XBee-PRO 900HP RF Module.
This manual is not a comprehensive manual that provides a full description of the
900HP RF Modem. This manual only covers the interfaces needed to communicate
with the 900HP 900 MHz RF Module. For an extensive guide on use of the 900HP 900
MHz RF Module, see the XBee-PRO 900 HP/XBee-PRO XSC RF Modules Product Man-
ual.
