Mounting

1. Mount the GBO-RS232 on a 4"x 4" junction box or directly

on a wall as shown in the Mounting Diagram. If metal con­duit is not being used, ensure proper earth/grounding of the
metal casing by connecting an earth/ground wire to the
earth/ground screw. Remove front enclosure cover to expose
terminal blocks, DIP switches, and output status LEDs.

Wiring Diagram

Important Notes

■ Install in accordance with all applicable regulations.

■ Do not connect line voltage/mains power to device. Improper wiring can result in personal injury or damage to the device or to

other equipment.

■ This control can use Class 2/PELV wiring methods. Check with your local electrical inspector for compliance with national and

local codes and wiring practices.

3/8 in. (10 mm)

2. Strip 3/8 in. (10 mm) of insulation from wires. Each terminal
will accept up to two #18 AWG (1.0 mm2) wires.

3. Connect wiring as shown in the Wiring Diagram. LED 1
will be lit when the MUX Link is properly installed.
Wires should be inserted through the circular punch­outs in the white metal enclosure so that the enclosure
cover can be replaced after installation.

4. Wiring to your Avant Television. For the RS232
Link, use the cable provided with the Avant Television,
Bang & Olufsen 4-pin USB cable (P/N 6270788). Wire
as shown below.

DIP Switches

The DIP switches determine which GRAFIK Eye Control Unit(s) the GBO-RS232 will communicate with.

When:

Dip Switch 1 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A1”.
Dip Switch 2 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A2”.
Dip Switch 3 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A3”.
Dip Switch 4 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A4”.
Dip Switch 5 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A5”.
Dip Switch 6 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A6”.
Dip Switch 7 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A7”.
Dip Switch 8 is “ON”- Unit will communicate with the GRAFIK Eye Control Unit addressed “A8”.

Note: The GBO-RS232 allows communication with up to 8 Grafik Eye Control Units.

Example:

In this example, DIP switches 1, 3, 4 and 7 are in the [ON] position. DIP switches 2, 5, 6 and 8 are in the [OFF] position. The
GBO-RS232 will communicate with GRAFIK Eye Control Units addressed A1, A3, A4, and A7.

RS232 Operation

The unit will communicate between an Avant Television and a GRAFIK Eye GBO Series Control Unit in a full duplex manner at
9600 baud.
It will understand the following RS232 commands:

:ON<LF> = Command will select scene 13 on the Control Unit addresses that correspond to the DIP switches

that are in the [ON] position.

Note: <LF> = $0A

:OFF<LF> = Command will select scene 14 on the Control Unit addresses that correspond to the

DIP switches that are in the [ON] position.

These comands are then acknowledged on the RS232 link as either ~on<LF> or ~off<LF>.

It also listens to scene selects on the GRX link that come from both control and wallstation units. If it hears a scene select of a
Home Theater scene (scene 13 or 14) that is going to a Control Unit whose address matches an [ON] DIP switch, it will issue a
command out of the RS232 port.

SCENE 13 produces: ON<LF>
SCENE 14 produces: OFF<LF>

The Avant Television has two seconds to send back the appropriate acknowledgement, or the message will be repeated two more
times, each having a two-second acknowledgement period. If there is no acknowledgement after three messages, the unit will give
up. A different message can be sent to the RS232 device before an acknowledgement is received. In this case, the first
message will not require an acknowledgement and will NOT repeat.
