MAKING CONNECTIONS TO THE CARD
The more commonly used signals are connected to the card from
the rear of the computer using connectors on the card’s bracket.
Other connectors for auxiliary functions are single or dual row
male headers on the card itself. The pins on these connectors
are numbered as follows:
Dual row headers oriented vertically on the card start with pin 1 in
the upper left corner. Odd number pins continue down the left
column of pins. Even numbers go down the right column of pins,
with pin 2 being at the top.
Single row headers oriented horizontally on the card have pin 1 on
the left.
See the appendix for information on the mating connectors for the
single and dual row headers. Cables which connect to the DB9
connector on the SX-6, SX-35, and SX-36 are available from An-
tex. The following wiring diagrams are provided to make your own
cables. Antex recommends using shielded twisted pair cable for
