Two-Card Expansion Board Installation Instructions
PNs 69782 and 71743
This document contains procedures for installing
two-card expansion boards in the wall and panel
mount models of 920i indicators. Procedures for each
enclosure type are described separately below.
See the Installation Manual, PN 67887, for general
installation and configuration information, including
option card slot numbering and port assignments.
NOTE:
The slot/location jumper on the two-card
expansion board must be set to the 3–4 position for all
standard installations. The 9–10 position is used only
in special applications using both six- and two-card
expansion boards.
For applications using both six- and two-card
expansion boards, connect the six-card board to the
two-card board using either cable PN 71799 (panel
mount units) or PN 71780 (wall mount units).
