This manual provided to the FCC for product guidance, it should not be used by our
OEM customers.
Scope:
This document will detail information required to install and use the VHF-2200 unit.
Introduction:
The Rockwell Collins® VHF-2200 contains two independent VHF communications
transceivers. Each VHF communications transceiver consists of a direct sampling A/D
converter type receiver, PLL controlled frequency synthesizer and RF amplifier
transmitter, I-Q modulator, DSP, and power supply. Both transceivers share a System
Processor that provides common Maintenance Reporting as well as ARINC 429 serial
and discrete interfaces.
Each transceiver within the VHF-2200 operates in a frequency range from 118.000 MHz
to 136.992 MHz selectable in 8.33-kHz increments. The VHF-2200 also operates in the
frequency range from 118.000 MHz to 136.975 MHz selectable in 25-kHz increments.
The VHF-2200 provides both voice and data communications. The 8.33-kHz channels
only support voice mode for receiver and transmitter communications, and the 25-kHz
channels support both voice and data mode for receiver and transmitter
communications.
Primary control functions are provided by the ARINC defined aircraft radio management
panel (RMP), this is accomplished by serial word control according to the ARINC 429
standard. Analog voice, VDL Mode A data, and VDL Mode 2 data communications
capabilities are provided by the VHF-2200.
A complete self-test capability checks critical components in all receivers and
transmitters for proper operation. The ARINC 429 serial tune bus is also tested to
ensure that the unit is receiving valid tuning information from the frequency selector
system. LED indicators are provided to verify LRU, external frequency control and
antenna/transmission line integrity.
Mechanical Description
The VHF-2200 VHF Communications Transceiver is housed in a 3 MCU case designed
to mount in a rack that conforms to the provisions of ARINC specification 600. The VHF-
2200 is structured with formed aluminum members that include a front panel, a rear
panel, a bottom panel, a top panel, a central partition that rigidly maintains the alignment
of the other panels, and swing-out side panels.

Installation:
The picture below details the VHF-2200 unit mounted in the ARINC 600 3MCU mount.
These type mounts have mechanical mechanisms to allow capture and restraint of the
front feet of the unit. This restraint ensures the unit will not come loose from the mount
and also that the ARINC defined connector does remains in contact with the rear pins.
The harness that connects the RMP to the VHF-2200 is defined by the aircraft
manufacturer. The pinout is defined by the ARINC 750 and 716 standard to allow
interchangeable product migration. The VHF-2200 pinout can be found below.
