RIU DIP switch and jumper settings
The RIU’s main circuit board contains one 8-switch DIP at location S1 and
a set of 14 jumpers at location J22, as shown in the illustration below.
1. Remove the screws that secure the top panel.
2. Raise the top panel to expose the internal circuitry.
3. Locate the DIP switches at location S1 on the corner of the circuit
board nearest the power switch. Switches are either On (Closed) or
Off (Open). DIP switch 1 must be Off and 2 must be On or the
Remote Interface will not start. Adjust the settings as necessary to
match the following table.
DIP Switch

1 Off (Open) Normal operation, Factory Use Only
2 On (Closed) Normal operation, Factory Use Only
3 Off (Open) Normal operation, Factory Use Only
4 Off (Open) Normal operation, Factory Use Only
5 Off (Open) Normal operation, Factory Use Only
6 Off (Open) Normal operation, Factory Use Only
