FCC COMPLIANCE
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
1. This device may not cause harmful interference
2. This device must accept any interference received, including interference that may
cause undesired operation.
WARNING: For compliance with FCC RF Exposure Requirements, the mobile transmitter
antenna installation shall comply with the following two conditions:
1. The transmitter antenna gain shall not exceed 3 dBi.
2. The transmitter antenna is required to be located outside of a vehicle and kept at a
separation distance of 10 inches or more between the transmitter antenna of this
device and persons during operation.
WARNING: CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY
ROCKWELL COLLINS COULD VOID THE USER'S AUTHORITY TO OPERATE
THE EQUIPMENT.
Note: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential
area is likely to cause harmful interference in which case the user will be required to correct
the interference at his own expense.
Note: If the FCC ID is not visible when the module is installed inside another device, then
the outside of the device into which the module is installed must also display a label
referring to the enclosed module. This exterior label can use wording such as the following:
"Contains Transmitter ModuleFCC ID: XEU2703240" or "Contains FCC ID: XEU2703240."
CAUTION
This unit contains static sensitive devices. Wear a grounded wrist strap and/or conductive
gloves when handling printed circuit boards.

1.0 GENERAL DESCRIPTION
1.1
SCOPE
This document provides the installation instructions of the Rockwell Collins Vehicle
Repeater System Module (VRSM), part number 270-3240-020. 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.

DEFINITIONS
For the drawings in this ICD, Figure 1 below defines the key for each drawing.
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.

P25 VEHICLE REPEATER SYSTEM INTERFACE DEFINITION
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.

2.2.1 P25 VRS ANTENNA CONNECTORS
There are two antenna connectors on the P25 VRSM. One is a TNC type connector
(Figure 3) and the other is a SMA type connector (Figure 4). These antenna ports
shall not be connected to an antenna with a gain greater than 3dBi.
Internally, these connectors attach via cabling to the individual transceiver cards
inside the VRSM. The TNC connector is a TNC Bulkhead Jack G3 (RG-178B/U), IP 67
rated, Telegärtner brand connector, part number J01011A2336. The SMA connector
is a SMA female-female hermetic bulkhead adaptor, Radiall brand connector, part
number R125.753.000.

2.2.2 P25 VRS DB-44 CONNECTOR
The DB-44 Connector on the P25 VRSM is defined in Figure 5. The DB-44 Connector
is a CONEC brand, part number 6HDD44PCY99R40X.
