CONNECTOR PINOUTS
VORTEX EF2201 Reference Manual 32 Technical Support: 800.932.2774
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, 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.
