DISPLAY connector (to operator interface)
The controller is connected to the operator interface through a 15-pin D-Type connector cable. One cable
end is connected to the DISPLAY connector of the controller. The other end connects to a 10-pin in-line
connector at the rear of the operator interface case. This cable end must be made, since some installations
may require the cable to be run through conduit. Table 13 shows the pinouts for the operator interface end
of the cable. Figure 25 shows the connector location at the rear of the operator interface.
