2100 or 2200 and the transmitter does not introduce tone distortion or produce too much

audio level compression, which may fool analog tone decoders.

Also, note that some paging tones are very close to the 2175 Hz tone often used and

removed by tone remote transmitter control equipment. Therefore, it is not recommended

that tone remote control equipment be engineered into the paging system. Instead, co-

locate the paging terminal and the transmitter. If this is not possible, then a D.C. remote

could be used.

Call Zetron Technical Support for further information.

Radio Connectors

Radio transmitter connections are brought into the Model 2100/2200 using a telco

standard 25-pair cable. The 50-pin mating connector is mounted to the Model 2100/2200

lower backplane (Z-bus) board, visible below the circuit card cage after the unit's front

door has been removed.

Ground the cabinet to a common earth connection using any of the screws holding the

backplane to the rear panel, or any of the nuts holding the side panels to the power supply

shelf.

There are no internal protection devices for lightning strikes, so external protection

devices, such as are available from Zetron are highly recommended to protect your

investment.

The charts on the following pages detail the pinout for the radio connectors.

Note Except where noted, station card Part No. 702-9038 and station

card Part No. 702-9441 are equivalent.
