IMPORTANT SAFETY INSTRUCTIONS For your safety, it is important to read and follow these instructions before operating a FOR-22 dual 4-wire interface: (1) WARNING: To reduce the risk of fire or electric shock, do not expose a FOR-22 dual 4-wire inteface to rain or moisture. Do not operate a FOR-22 dual 4-wire interface near water, or place objects containing liquid on it. Do not expose a FOR-22 dual 4-wire interface to splashing or dripping water.
CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol alerts you to the presence of uninsulated dangerous voltage within the product's enclosure that might be of sufficient magnitude to constitute a risk of electric shock. Do not open the product's case. This symbol informs you that important operating and maintenance instructions are included in the literature accompanying this product.
1 OPERATING THE FOR-22 INTERFACE This chapter describes how to use the FOR-22 dual 4-wire interface. System operators can use this manual once the Eclipse System is correctly installed and configured with the Eclipse Configuration System (ECS) software, and after the FOR-22's internal jumpers are set. For information on configuring the FOR-22 interface, see the separate manual for the Eclipse Configuration System.
The installation chapter of this manual gives more information on interface frames and on wiring the FOR-22 unit to the matrix and to external devices. OPERATION In normal use, the FOR-22 interface does not require operator interaction. Each channel features the same set of front panel controls: • A "send" level control • A "receive" level control • A "send level" LED • A "relay active" LED "SEND" CONTROLS The "send" controls affect the level of the signals from the matrix to the external devices.
2 INSTALLING THE FOR-22 INTERFACE This chapter includes the following topics about installing the FOR-22 interface: • Overview of interface frames and power supplies. • Installing the interface in an interface frame. • Wiring the interface to the matrix and to external devices. • Adjusting the interface’s front-panel controls after installation.
For more information on the IMF-3 frame, refer to its manual in the Eclipse manual set. POWER SUPPLY #1 CH. A Matrix CH. A Matrix CH. A Matrix CH. A Matrix CH. A Matrix CH. A Matrix CH. A Matrix CH.

INSTALLING THE FOR-22 IN AN INTERFACE FRAME IMF-3 INTERFACE FRAME This section describes how to install an FOR-22 unit in an IMF-3 frame.
• Microphone level ----------------- -55.0 dBu at 20 ohms To set channel 1 for the desired level: 1. Find jumper block JP100 on the circuit board. 2. Move the jumper so that it connects the pair of jumper pins labeled with the desired level (Line, IFB, or Mic). To set channel 2, repeat the above procedure using JP200. Each FOR-22 channel can also be adjusted using its "Send" front panel control. See Figure 3-1 in Chapter 3 for a diagram of the FOR-22 main PCB showing the location of the jumpers.
WIRING The FOR-22 interface connects to an Eclipse matrix through the two RJ-45 connectors on the IMF-3 or IMF-102 rear-panel assembly to which the FOR-22 unit is connected. One RJ-45 connector is for the first channel of the interface. The second RJ-45 connector is for the second channel. Figure 2-3 shows pin assignments of the RJ-45 connectors used to connect the interface to an Eclipse matrix.

Both audio input and output are transformer isolated. Refer to Figure 2-4 for pinouts.
ADJUSTMENTS After installation the front-panel controls should be set to accommodate the normal range of input and output levels encountered. The following is a discussion of the controls and indicators on the front of the interface. "Send Level" Control The "send level" control allows adjustment of the output level of the channel from the matrix to the external device/system.
