Note The information below lists manufacturer information for the terminal block
connector that is compatible with the parts we use:
Manufacturer: Phoenix Contact
Description: Mini-COMBICON 3-position plug, 3.5 mm pitch
Type Number: MC 1.5/3-ST-3.5 or MC 1,5/3-ST-3,5
Part Number: 1840379
Input/Output Remote Control Port
Logic Input
: Pins 1-24 are inputs 1-24,
respectively. Pin 25 is ground.
Logic Output: Pins 1-20 are outputs 1-20,
respectively. 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 resistance.
Power Supply Input
The power supply input accepts a 5-pin DIN
male connector. Only use the power supply pro-
vided 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 Out-
puts
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.
