  • Page 5 Please read and follow these manual. instructions before operating (3) Do not install the FOR-22 near a heat source such as a radiator, heat register, the FOR-22 4-wire/radio stove, or other apparatus (including amplifiers) that produces heat. Do not place naked flame sources such as candles on or near the FOR-22.
  • Page 6 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 main- tenance instructions are included in the literature accompanying this product.

    4-wire devices, allowing the matrix and the 4-wire devices to communicate with each other. The external 4-wire devices that you can connect to the matrix with the FOR-22 interface include camera intercoms, two-way radios, microwave and satellite links, IFBs, and program audio.

  • Page 8: Operation

    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"...

    To house these interface modules, Clear-Com offers various types of interface frames. The two frames which can house the FOR-22 dual 4-wire/radio interface are the IMF-3 and the IMF-102 frames, which are described below.

    3. Set any necessary Audio Output Level Jumpers. 4. Set any necessary Audio Input Level modifications. 5. Slide the FOR-22 in the slot and ensure that the card is fully seated. 6. Tighten the FOR-22's front panel mounting screws. IMF-102 INTERFACE FRAME The IMF-102 interface frame contains two slots for installing interfaces.
  • Page 12 AUDIO INPUT LEVEL GREATER THAN +10 DBV To accommodate input levels greater than +10 dBv on either channel, the FOR-22 circuit board can be modified to build bridging pads on the primary side of each channel's input transformer. To build a bridging pad: 1.

    Connector Figure 3: Matrix to Interface Frame Wiring The "user" side of the FOR-22 for each channel is on a DB-9M connector on the rear of the IMF-3 or IMF-102 frame. Figure 4 shows the pinout of either one of these connectors.
  • Page 14 Figure 4 for pinouts. RELAY CONTACTS Each FOR-22 channel features a relay that is associated with the logical "call signal" output of a port. A relay's function depends on the function assigned to the FOR-22 port in the configuration software. A relay can be assigned to operate with any label in the system: when that label is activated (either by a talk, listen, or both as set from the configuration program), the relay will be activated.

  • Page 15: Configuration

    LED is normal. CONFIGURATION You configure a central matrix port to work with the FOR-22 interface by setting parameters in the Eclipse Configuration System (ECS) programming software. Refer to the Eclipse Configuration System Instruction Manual for more information.
