Remember: Disconnect power before servicing internal components!
TNMC Current Loop Interface (CLI) Card
The CLI card, located on the rear-access panel of the TNMC, translates the signal media to
TIA/EIA-232 (formerly RS-232) for use within the components of the TNMC. The signal transfers
into the TNMC controller where that component interprets and distributes the data to the modules.
Refer to
Drawing A-145045 .
TNMC Controller
The controller, located on the rear-access panel, receives signal from the CLI and sends data to the
modules. Refer to the signal summary in
Section 9.3 for more information and to Drawing A-
145045 for the position of the controller board. Figure 7 , below, illustrates a typical controller.
