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.
