CPI Communications MR200(N) Series - Manual (Page 3)

2.0 General Infomation
The CPI MR200(N) series termination panel provides a reliable means of interfacing a tone remote to most Mo-
torola mobiles that use the 8 pin microphone jack. The MR series can be used with any tone remote that uses the
industry standard EIA sequential tone format such as the CPI TR series remotes. The only available option for the
MR200(N) is special software for non-standard keying tones and F1/F2 operation - MR202(N).
Jumper selectable -4W/FD is standard as well as automatic gain control, and transmit and receive audio notch
filters are standard.
3.0 Installation
The MR200(N) is housed in a sturdy vinyl clad steel and aluminum enclosure. Connection to the radio is made
through the included RJ45 cable that is simply plugged into the radio microphone jack of the radio and the radio
input jack on the front of the MR200(N). Due to the design of many of the newer Motorola radios, remote vol-
ume may be affected by adjusting the radio volume.
A modular jack is also provided on the front of the MR200(N) for a control station desk or palm microphone. If
a local microphone is not used, pins 2 & 3 of JP13 must be shorted to allow monitor function to operater cor-
rectly.
The MR202(N) provides a two channel relay that can be used in momentary or latched mode. Two channel
operation varies from radio to radio and this feature may not be used in some applications. Jumper settings are
on schematic sheet 1. Note: F1/F2 operation requires that a jumper be added in the radio to toggle the channel
selection or a channel select line at the accessory connector may also be used.
Remotes are connected to the MR200(N) at the J3 modular connector on the rear of the unit or to the J4 screw
terminal connector.
Power to the termination panel is made by providing +13.8 Vdc and ground to the J4 terminals (pins 1 & 2) on
the back of the panel.
TX and RX audio levels are preset for 0 dBm and should not require adjustment. Instructions for re-adjustment
are provided on page 4 and 5.
2 Wire/4 Wire Full Duplex operation
The MR200(N) termination panel is 2 wire/ 4 wire full duplex capable by selection of the JP1 jumper on the
panel.
2 Wire - Jumper JP1 should be in the 1 & 2 position
4 Wire/ Full Duplex - Jumper JP1 should be in the 2 & 3 position
