AR2200 RF Module Overview
2-7
Output Power
The output power of the RF module is set at the factory to 1.6 W.
Options
The following two options are available for the RF module.
Harsh Environment Option
The RF module has a harsh environment option, which is vibration- and shock-
resistant. The vibration specification for the harsh environment RF module is
2 g RMS from 5-500 Hz.
Custom Frequencies
The RF module can be set at the factory to operate at a discrete, narrow band
frequency. This option avoids frequency interference from other closely-situated units
operating at similar frequencies. If your application requires an operating frequency
outside of the 902 to 904 MHz or 909.75 to 921.75 MHz bands, contact TransCore.
Local laws apply in the determination of operating frequencies.
Replacement I/O Interface Board
The I/O interface board is the only replaceable part in the RF module. A ribbon cable
to connect to the RF subassembly is permanently wired to the RF interface board.
Accessories
The following accessories are available for the RF module.
Attenuators
Five-watt 1- to 24-dB attenuators with N-type connectors are available from
TransCore. Other attenuators may be available for specialized applications; contact
TransCore for information. Power output can be reduced by up to 7 dB using the RF
module’s RF power output select feature.
Hex Key
The hex key, used for removal and installation of RF module and reader circuit
boards, has a 0.16-in. (4-mm) hex cross-section and a 9.13-in. (230-mm) shaft.
Weatherproof Enclosure
The RF module may be housed in a weatherproof NEMA-4 enclosure ready for
custom installation. Enclosure locking loops accept padlocks with a maximum 1/4-in.-
(6.3-mm-) diameter shackle.
