In an alternate application, the Model 66 can be colocated with the Model 640 and the trans-
mitter for simulcast systems. The connections between the Model 66 and the paging transmitter
are identical to those shown in Figure 43. Figure 44 illustrates the connections between the
paging terminal and the Model 66.

Model 68 Transmitter System Controller Interface
When a Zetron Model 68 Transmitter System Controller is interfaced to the Model 640, the
paging output can be directed to up to 16 transmitter zones. The Model 68 steers the output from
the paging terminal to any one of 2-16 local or remote paging transmitters, dependent upon
installed options. For technical details related to operation and/or installation of the Model 68,
refer to the
Model 68 Transmitter System Controller Operating and Installation Manual
(Part
No. 025-9089). Figure 45 shows the layout of the Model 68 radio station connectors.

The specific wiring connections between the Model 68 and the Model 640 depend on the telco
and radio station installation method previously chosen. Recall that the 50-pin RJ21 connector on
the Model 640 provides both trunk and radio station signals for the paging terminal. The two
basic installation methods are the terminal block adapter and one or more 66-type punchdown
blocks.
Note:
A special software update is required to interface the Model 68 to the Model 640. The
programming ensures that the AUX and DIG PTT both key prior to the HLGT (high
