NOTE: 1) The baud rate setting does not affect the switcher port, which is always
9600 baud. 2) See Serial Port Connections and Appendix D for more information
about cable connections between devices.
FRONT IR -
As described in Section 2, the standard IR remote keypad is capable of
sending data to the projector in either one of two protocols called
A
or
B
. Likewise,
the front IR sensor on the projector can be set to accept IR data accordingly,
responding to A, B or Both. The projector’s A, B or 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
projector at a time.
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 manufacture to
"Protocol A". See Keypad Protocols 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 protocol (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
Keypad Protocols 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 the IR
remote to execute the protocol change for the wired keypad. The projector will now
recognize only the opposing wired keypad protocol. Or, if you prefer, use the wired
keypad to safely change its own protocol:
1. Select the
A or B
option. This will ensure that once your keypad is manually
changed (see Step 2), it will still be recognized by the projector.
2. Unplug the keypad and change the protocol in the keypad as desired. Do this
either by hard-wiring the keypad as described in 2.10, Keypad Protocols and
Conversion.
3. Plug the keypad back into the projector. Return to the Communications menu and
select the new protocol you have just set up in the wired keypad.
TURNING OFF THE WIRED KEYPAD:
If you want to disable the wired keypad entirely,
you cannot use it to select the
OFF
option. This safeguard prevents you from
