OPERATION
Front IR / Back IR
As described in Section 2, the standard IR remote keypad is capable of sending data to the pro-
jector in either one of two protocols called A or B. Likewise, the front and rear IR sensors on
the projector can be set to accept IR data accordingly, responding to A, B or
both. The projector’s A or B default is adequate for most single-projector
installations. Select a specific protocol to prevent interference when you are
controlling two protectors in the same area and want to work with one projec-
tor at a time.
Note that the front and rear IR sensors cannot respond to different protocols-if you change a
protocol for either sensor to anything other than OFF, the protocol for the other sensor also
changes. For example, setting Front IR to B also changes the Back IR to B. If you want only
one sensor to respond to a particular protocol-A, B, or A or B-disable the other sensor by set-
ting its protocol to OFF.
If you want to disable both IR sensors, you cannot use the IR remote keypad to select the sec-
ond OFF setting. This safeguard prevents accidentally disabling a keypad while you are using
it. Instead, use either the built-in keypad or the wired remote to set the remaining active sensor
to OFF. The projector will no longer respond to an IR remote keypad.
IMPORTANT
Keep at “A OR B” unless you are sure of
the current IR keypad protocol.
NOTES: 1) The IR remote keypad for this projector is set at Runco to “Protocol A”. See 2.10,
Keypad Protocols and Conversion for information about changing the keypad protocol. 2) A
key press from a conflicting protocol will cause a single yellow flash on the Status LED located
in the lower right corner of the rear projector panel.
Wired Keypad
Like the IR remote keypad, the optional wired keypad is either a “Protocol A” keypad (default)
or a “Protocol B” keypad. Likewise, the projector can be set to accept wired keypad data
accordingly, responding to A or B. If desired, you can prohibit the projector from responding to
a particular wired keypad protocol, or you can ensure that the projector responds to either pro-
tocol (default). You can also prevent the projector from responding to the keypad entirely. In
the pull-down list, select the desired protocol.
NOTE: The wired keypad for this projector is set at manufacture to “Protocol A”. See 2.10,
Keypad Protocols and Conversion for information about changing the keypad protocol.
ADDING A PROTOCOL: To add a protocol, select the A or B option.
CHANGING A PROTOCOL: As a safeguard, you cannot accidentally select an option in the
“Wired Keypad” list that would disable the wired keypad during use, since such options are
automatically disabled in the list. In other words, you cannot switch to the opposite protocol or
select OFF using the wired keypad. Instead, if you want to quickly change to the other protocol,
you may find it more convenient to use one of the other keypads (the built-in keypad or the IR
remote) to execute the protocol change for the wired keypad. The projector will now recognize
only the opposing change for the wired keypad protocol. Or, if you prefer, use the wired keypad
