Every pair of Transmit and Receive Cards that will be communicating with each other through one of their
ports must be configured for the length of the Expansion Cable(s) that will connect them together. This
involves setting a series of “distance jumpers” for each port on each card. (Remember that, should you decide
to connect the two ports of an Transmit Card to ports on two different Receive Cards, or vice versa, you will
need to set the ports’ jumpers differently.)
Take these steps for each such pairing of Transmit and Receive Cards in your system:
1. Orient a pair of Transmit and Receive Cards as shown in Figure 6-8. (Because of the way its components
are labeled, it’s easier to read the regular Receive Card if you hold it with its port connectors to the left.)

2. Choose which port on the Transmit and Receive Cards you will be connecting your Expansion Cable(s) to:
the lower one (#1) or the upper one (#2). You may use either, but if you choose Port 1 on one Card, the
cable(s) attached to it must run to Port 1 on the other Card; likewise Port 2 must be connected to the
other Card’s Port 2.
3. Referring to Tables 6-2 through 6-4 on the next two pages, set the appropriate jumpers on each Card
according to the port chosen and the length of the Expansion Cable that will connect them. As you
configure each Card, fill out a record for it on a copy of the Transmit- or Receive-Card System-
Configuration Chart (Chart A-3 or A-4 respectively in
Appendix A
).
After all of the Cards have been configured, they are ready to be installed. Follow the directions for doing this
in
Section 6.4
