RUGGEDCOM RX1100
Installation Guide
Most active antennas include filters. However, if there is a high potential for electromagnetic interference, such
as from the near field of a radio transmitter, though the antenna system, additional antenna line filtering may be
necessary.

RS232 External Modem Ports
The optional RS232 external modem card provides all of the handshaking signals required to control an external
modem via a female DB9 connector.
The following is the pin-out for DB9 ports operating in RS232 mode:
Figure 29: Serial DB9 Port Pin Configuration
NOTE
Although a DB9 RS232 DTE (Data Terminal Equipment) connector is ordinarily male, the female
connector has been used here for reasons of durability (i.e. there are no pins to bend). Use a
commonly available male-to-male DB9 adapter (not a NULL-modem) to adapt this connection to a
standard straight-through RS232 cable.
Section 3.10
Cellular Modems
The RX1100 supports the following cellular modem line modules for operation on GSM, EDGE, HSPA+, or CDMA
networks:
NOTE
The cellular modems feature 50 Ω SMA antenna connectors on the front plate of each module.
The HSPA option is available for use on various GSM-based networks. This option supports GSM,
GPRS, EDGE, UMTS and WCDMA/HSDPA/HSUPA. The Main antenna and Receive Diversity antenna
connections are made to the 50 Ω SMA connectors.
The following sections describe the cellular modem modules in more detail:
