SECTION 2 - DESCRIPTION AND OPERATION
INTRODUCTION
This section explains the circuits, power and connections for
the Configuration Port Module (CPM). The CPM connects a Con-
figuration Tuning Terminal (CTT) to the INFI 90/Network 90
system. The CTT hand held terminal allows you to configure,
monitor, tune and run diagnostics on the system. The CTT con-
nects with the system through the CPM (P1) and the module
bus as shown in Figure
1-1 . Figure 2-1 shows the schematic of
a CPM.
INPUTS AND OUTPUTS
Digital signals to and from the CTT are +5 VDC. Section 3
explains the module connections.
Input and Output Circuit Description
Figure 2-2 shows the board circuitry on the CPM module. The
board circuitry consists of signal traces and a 0.5 Amp fuse to
protect the CTT and the system circuitry. The circuits provide
300 Volts isolation by using PCB trace separation to CSA stan-
dards.
Input and Output Circuit Connections
The input and output signals pass through the module bus
and P1 to the connector on the front of the CPM. The CTT con-
nects to the five pin connector on the front of the CPM with a
five foot flexible cord.
