For data communications, the radio has an industry-standard TIA/EIA/RS-232C type 9-pin serial
interface port for connecting optional data-type equipment, a laptop PC, an external display, or a key-
entry device. This port works seamlessly with equipment from popular manufacturers and off-the-shelf
applications. This port can also be used for radio program operations, and radio diagnostic functions.
The radio also has a built-in Global Positioning System (GPS) receiver. This receiver provides position
and speed tracking and accurate time via the control head’s display. It also provides GPS
NMEA-formatted serial data to several pins on the radio’s rear panel 44-pin connector. This is provided
for external equipment running third-party GPS-related software. The GPS receiver’s antenna can be
integrated into the mobile transmit/receive antenna (i.e., a “combination” antenna). Alternately, the GPS
antenna can be located/mounted completely separate from the mobile transmit/receive antenna. As of the
publication of this manual, over-the-air GPS data messaging is not
supported.
For over-the-air secure radio communications, the Unity XG-100M mobile radio may be optionally
equipped for 256-Bit Advanced Encryption Standard (AES) voice encryption or 64-bit Digital Encryption
Standard (DES) encryption. With encryption, voice and/or user data signals transmitted and received by
the radio on an RF channel are digitally encrypted (“scrambled”) to virtually eliminate unauthorized
monitoring via the RF channel. DES encryption is offered in both standard Output Feedback (DES-OFB)
and Cipher Feedback (DES-CFB) formats.
The Unity XG-100M mobile radio and its control heads exceed tough environmental specifications
included within military standard MIL-STD-810F, the radio industry standard TIA/EIA-603, and the
radio standard established by the U.S. Forest Service.
