Troubleshooting - Polycom EFIR10 Instruction Manual

ROUBLESHOOTING
• Make sure the receiver is plugged in. There should be a red LED that is lit
constantly on the top right of the receiver.
• Check the Device ID of the EF Device. An incorrect ID will prevent the
receiver from sending commands to the device.
• Check the flow control and baud rate of the EF Device. The receiver
transmits at 9600 baud with no flow control. Any deviation from those
settings inside the EF Device will prevent the receiver from sending
commands to the device.
• If you have multiple EF Devices linked together (via EF Bus or ASPI Bus),
leave the PC connected to one EF Device and open the Console Window
of Conference Composer. Connect the EFIR10 to another EF Device and
push buttons on the transmitter. You should see activity in the Console
Window (assuming the Device ID and flow control / baud rate settings are
correct).
• If you are using a RS-232 cable (greater than 50 feet), double check the
wiring.
• The cable should be wired straight through, i.e. pin 2-2, pin 3-3, and pin
5-5.
• If you are using an infrared repeater, make sure it can pass a 38 kHz
signal. Try pointing the transmitter at the receiver and see if the receiver
sends the command.
