This section specifies how RS-232 should be wired to the Epson projector. Although this driver is RS-232-only, SP Controls strongly recommends that you also wire IR in case you make a decision to use Revision C of this driver, which uses IR control. Please Section III below for more information.

RS-232 should be connected to the Epson control port labeled CONTROL (RS-232C). Connection should be as follows:

1.Wire the Panel to a female DB9 as follows: TX to 2

RX to 3 GND to 5

2.Connect this female DB9 to the projector port labeled CONTROL (RS-232C).

The Infrared emitter (squirt) bud should be attached to the rear IR window. IR control does not work effectively from the front projector IR window.

Connection should be as follows:

1.Wire the Panel to a female 1/8" Mini as shown; wire IR/SER to tip and GND to ring. Direct wiring to the IR Emitter is not recommended as it makes removal of the Panel for service more difficult.

2.Attach to any projector IR port using the Panel’s IR Emitter (included with the Panel).

Note that the emitter glows red when IR is emitted so wiring can be verified.

SPECIAL CONTROL NOTE 1:

The Epson EMP-7800 projector must be configured to STANDBY MODE: NETWORK ON in the projector onscreen menu ADVANCED1. If the projector STANDBY MODE is not configured to NETWORK ON, it may stop responding to RS-232 commands.

If the projector does stop responding to RS-232 control, manually power down the Epson projector. Once the projector cools down, unplug the projector from the outlet and allow it 15 seconds to reset. Reapply power and the projector should work normally.

Note: When the projector is placed in STANDBY MODE: NETWORK ON the projector fan remains on in standby mode. This is normal projector behavior.
