Connecting Two SI-32 Units
By chaining two SI-32 units together, there is a total of 60 switches available. To operate
correctly, the following conditions need to be observed:
1.
The first SI-32 will control switches 1-32 and the second will control switches 33-60.
2.
DIP switch four will be set on one unit, so that the units can be used together.
3.
On each SI-32, set the DIP switch for the mode of that unit.
4.
In most cases, the two units must be set to the same mode. Only when using toggle
and momentary modes, can two different modes be set.
5.
Both units cannot be used to send a switch command to the displays at the exact
same time.
SI-32 Setup
1.
Connect from the computer to the first
SI-32 at J1, RS232 IN.
2.
Using a flipped RJ11 cable, connect
from J3 (RS422 OUT) on the first SI-32 to
J2 (RS422 IN) on the second SI-32.
3.
From the second SI-32, connect to the
display.
4.
When chaining the SI-32 units, set DIP
switch S4 to the “ON” position on one
unit.
for the DIP switch setting.
