The Config Switch provides an alternate method for entering into
Command Mode. To enter Command Mode at the default RF data rate
of the modem, hold the Config Switch down for two seconds.
LEDs indicate modem activity as follows:
Standard female DB-9 (RS-232) connector. This connector can be
also used for RS-485 and RS-422 connections.
RSSI LEDs indicate the amount of fade margin present in an active
wireless link. Fade margin is defined as the difference between the
incoming signal strength and the modem's receiver sensitivity.
7-28 VDC* power connector (Center positive, 5.5/2.1mm)
During each power-on sequence (reset or boot), the modem is auto-
matically configured according to the positions of the DIP Switch. The
DIP Switch provides integrators with a limited number of external
programming options. [Refer to Figure 1-03 for configuration options]
The antenna port is a 50Ω RF signal connector for connecting to an
external antenna. The connector type is RPSMA (Reverse Polarity
SMA) female. The connector has threads on the outside of a barrel
and a male center conductor.
