APPENDIX I: IRR ADVANCED SETUP MENU/TROUBLESHOOTING
Eco Manual
314
The Advanced IRR Menu allows you to set unit codes for your communication aid and its
devices. If you are the only person using your communication aid with other IR devices,
everything in this menu defaults to "1" which is just fine for you. If you are in a multiple device
situation, you and the other people using communication aids must decide which one will talk to
which devices and assign the correct Unit Number to each device. For example, you might
assign Unit Number 1 to your communication aid, EZ Phone and IRR, while your neighbor gets
to use Unit Number 2 for her communication aid, EZ Phone and IRR.
When you assign a Unit Number, your communication aid and all the devices that it will be
sending signals to
must have the same Unit Number.
Protocol Options
There is an option in the Advanced IRR Menu that allows you to choose the kind of protocol
you want the IRR to use in order to receive signals from your communication aid. The protocol
choices are PACKET or PIPELINE.
PACKET PROTOCOL
Allows you to have more than one communication aid and IRR in the room, with all of them
receiving the same signals at the same time. Packet protocol allows you to assign a Unit Number
to each device. Packet protocol also checks for errors in the infrared communication and screens
out infrared information from outside sources. This provides for more accurate infrared
communication. 1200 baud must be used with this protocol.
PIPELINE PROTOCOL
Does not check for errors in the infrared information it receives. It does not allow you to assign
Unit Numbers for more than one infrared device. It does not screen out infrared information
from outside sources. This means that accurate infrared information may be difficult to achieve
in some situations. You can use either 1200 or 300 baud with this protocol. Character Pacing
must be used with this protocol.
If You are Using an IRR and You Get an Error Message on your Device
If the IRR doesn't receive the infrared signals you send from your communication aid, the
display will show the message, "Remote IR device is not responding. Please wait or activate the
Text Display area to cancel."
Make sure your device's IR window is facing the infrared window on the IRR. Check to make
sure nothing is blocking this line-of-sight between your device and the IRR. If something is in
the way, remove it and the signal should go through.
The infrared signal that your device sends is very strong. If the device and IRR windows are
closer than 18 inches to each other and are directly facing each other, the IRR may not be able to
read the communication aid's signal. Either move the communication aid farther away from the
