Logic Input: Pins 1-24 are inputs 1-24, respec- tively. Pin 25 is ground.

Logic Output: Pins 1-20 are outputs 1-20, respec- tively. Pins 21-25 are ground. Each ground pin should be used with only 4 outputs. For example, outputs 1-4 could be connected to LEDs, which are connected to ground pin 1.

LEDs can be used without series resistors (we have provided series resistors in the circuitry). For best results, LEDs with Vf=2.0 V and If=20 mA should be used. Larger values may be used, but may result in dimmer LEDs. An LED with Vf less than 1.4 V should not be used without additional series resis- tance.

Power Supply Input

The power supply input accepts a 5-pin DIN male connector. Only use the power supply provided by Polycom. Use of other power supplies will void the warranty.

1 Ground; 2 Ground; 3 +5Vdc @ 3 A; 4 -15Vdc @ 0.3 A; 5 +15Vdc @ 1.2 A

Mic/Line Inputs, Line Inputs, Line Outputs

These audio connectors accept a mini (3.5 mm) 3 conductor terminal block (provided). See Note below for manufacturer information.

From left to right the conductors are positive signal, negative signal, and shield ground.

Note The information below lists manufacturer information for the Phoenix connector that is compatible with the parts we use:

Once the parameter is flashing, use the UP and DOWN buttons to adjust the parameter value. The parameter is instantly updated while it is being adjusted - you should hear changes as the parameter is changing. RS-232 control strings are also sent via the RS-232 port so your remote control device is instanta- neously updated as well. Press ENTER to select and store the parameter value or press ESC to cancel the selected value and return to the old value. Pressing HOME has the effect of pressing ESC then HOME, so the selected value will be cancelled and the menu will return to the top of the menu tree SYSTEM MENU Figure 17.

If the reflected signal picked up by the microphone is higher than the level of the signal sent to the line output to your amplifier, that microphone channel has positive room gain. The more positive the room gain, the harder the AEC must work to determine which signal is an echo and which is a local speech signal INDEX Mic/Line Inputs, Line Inputs, Line Outputs Page Page Polycom, Inc Installed Voice Business Group 1725-80098-001-C1720 Peachtree Street NW, Suite 220 Atlanta, GA Phone 800 932-2774, 404
