DESCRIPTION AND OPERATION

2 - 10 WBPEEUI240756A0
®
Bailey-Fischer & Porter FSK style smart transmitters (Fig. 2-7).
In this mode, the analog signal from each smart transmitter
goes to an individual input channel (point-to-point). Because
the inputs are analog point-to-point, the FEC module can
interface any combination of devices while it is in this operat-
ing mode. For example, in addition to FSK smart transmitters,
conventional transmitters can input process data but cannot
communicate with the FEC module. The NTAI05 termination
unit or NIAI04 termination module provides point-to-point ter-
mination. Dipshunts select the type of input signal for each
channel. Function code 133 must be configured in the MFP or
MFC device for every five analog inputs from each FSK device.
