Twinax cable and twisted-pair cables can be combined. The following formula shows
lengths:
(twinax length) + (5 x twisted-pair length) < 1370 meters (4500 feet)
1. Locate the twinax cable extending from the host system or from the closest device on the host
system side of the line. Attach the connector at the end of this cable to either socket on the two-
socket end of the T-connector cable.
2. Push the connector into the socket and turn the retaining ring clockwise until tight.
3. If there are other terminals in the daisy chain, connect the second cable from the next terminal to the
unused socket of the two-socket end of the T-connector cable before attaching the T-connector
cable to the back of the logic element.
4. Align the 9-pin Sub-D connector end of the T-connector cable with the twinax connector on the
back of the logic element. Connect the cable to the logic element and secure it in place by turning
the retaining screws until tight.
5. Make sure the twinax line is terminated properly. The last T-connector should have one input open.
If the last device is a Visara device, it must have a T-connector. If the last device is not a Visara
device, ensure that it is terminated correctly according to the manufacturer’s instructions.
Note:
When one connector of the two-socket end of twinax cable is unattached, the
cable is self-terminating. When the single end of the connector cable is
unattached, the cable is in Pass Through mode, and signals continue on to the
next connected device. Never attach the twinax cable directly to the logic
element.
