Two-Card Expansion Board Installation
This document contains procedures for installing two card expansion boards in the deep universal, wall and panel mount
models of the 920i indicator. Procedures for each enclosure type are described in this document.
See the 920i manual (PN 67887) for general installation and configuration information, including option card slot numbering and
port assignments.
For applications using both six- and two-card expansion boards, connect the six-card board to the two card
board using cable ((PN 71799) for universal and panel mount units or cable (PN71780) for wall mount units.
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 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).
