The unit is intended for use by government agencies or contractors thereto whom have obtained licensing within the frequency range listed in Table 1 below. The Rockwell Collins VRSM is a full duplex P25 radio module consisting of two Nexus XR25 transcievers capable of operating in the 764 MHz to 869 MHz frequency range. The VRSM has the ability to operate in both analog and digital communications. The purpose of the VRSM is to allow a portable radio to transmit and interface with a moble radio while repeating the transmission to other portable radios in the area on the selected channel. The VRSM is capable of programming frequency, CTCSS tones, and P25 Network Access Codes (NAC) information. In addition, the RF power output can be adjusted from 0.1W to 2.0W to reduce interference with other nearby systems. 1.2 TECHNICAL CHARACTERISTICS The VRSM consists of two identical transceiver boards. Table 1 describes the high level specifications for the transceiver.

Figure 1 ICD Drawing Key For the tables in this ICD, the following definitions shall be used:
Function: Function is the description of the pin(s) and what data should be expected from it. Function should include what protocol and/or intended use. Function usually is fairly descriptive of the function being performed on that pin or set of pins, i.e. Mobile PTT Output, or RS-232. Signal Type: Signal Type is the kind of signal/message being sent. Signal Types can be Ground, Analog, Serial Digital, G/O Discrete, RF, 12VDC Battery, etc. I/O: I/O is the direction of the signal, I (Input), O (Output), or G (Ground Return). Pin: Pin is the physical pin or wire number on the connector. It may also be the wire color in the cases where pins are not numbered. Comments: Comments will contain any information pertinent to the pin. This might include voltage levels, current limits, impedance limits, wire types, or even a longer description of the intended use of the pin. Rockwell Collins, Inc. Proprietary Information. 2 2.2 P25 VEHICLE REPEATER SYSTEM INTERFACE DEFINITION Vehicle Repeater System Module Installation Manual This Interface Control Drawing (ICD) provides a description of the interfaces within the VRSM. Logical interfaces are defined as digital communication paths represented by industry digital standards such as the EIA/TIA/RS-232 standard. The ICD provides connection diagrams, and pin descriptions with logical interface protocol information. The VRSM contains a pair of RF connectors to interface with antennas. These connectors are detailed out in Section 2.2.1. Internally, all interfaces on the XR-25 transceiver boards are brought out to a single connector. Each transceiver board has an RF side and a digital side, where the single connector is brought out on the digital side. The connector is referred to as the host interface connector. Each of the two transceiver boards will reside on a carrier board within the module housing. The carrier board will provide power filtering, audio attenuation, and digital signal level conversion. The carrier board has the power and data connections to the external surface which is detailed in 2.2.2. Figure 2 below details the connection of the VRS to the system.
