Connecting the Display Station to the Host System
Connect the display station to the host or to a controller with a coax cable up to 1500
meters (4920 feet) long, or a twisted-pair cable with a minimum length of 30.5 meters
(100 feet) and a maximum length of 277 meters (900 feet). Coax cable and twisted-pair
cables can be combined. This formula shows lengths:
(coax length) + (5 x twisted-pair length) < 1370 meters (4500 feet)
Follow these steps to connect the display station to the host system or to a controller:
1) Locate the coax or twisted-pair cable extending from the controller.
2) Align the end of the connector cable with the Dual Purpose connector on the back of
the Display/Logic element (see Figure 2-4). Connect the cable and secure it in place
by turning the retaining ring clockwise until it is tight.
