16.1.5 Rear Panel Connections
Figure 16-6 shows the connection points for
terminal block TB1 on the rear panel of your
TCF–10B carrier set. It also shows the function of
each position, or connection point. You make all
your relay connections for both microprocessor
based and electro-mechanical type relays to this
terminal block.
For additional diagrams showing all the external
(rear panel) connections for your TCF–10B,
please refer to Figure 3-4 and Figure 3-5 in
Chapter 3 and Figure 7-1 in Chapter 7. For DIN
connector pinouts for each application, please see
Figure 16-7 (2-F Directional Comparison), Figure
15-8 (3-F Directional Comparison), and Figure
15-9 (2-F Phase Comparison).
16.2 Receiver Logic Signal
Paths
The Receiver Logic Module has a different signal
flow for each type of application. This is due
primarily to the different plug-in EPLD chips
used. The input signal (from the Receiver/FSK
Discriminator Module) and your DIP switch
settings also play a role. Figures 16-7, 16-8, and
16-9 provide functional block diagrams showing
the logic and signal path for each application (2-F
Directional Comparison, 3-F Directional
Comparison, and 2-F Phase Comparison, respec-
tively).
These three figures also show the logic states for
the input from the Receiver/FSK Discriminator
Module and (for the Directional Comparison
applications) the output
to the EM Output
Module, the DIP switch
settings, and the DIN
connector pinouts —
providing a compre-
hensive look at the
module’s signal flow.
