Instant Call Left Column Function
Jumper JP1, on the instant call panel driver board (702-9023-001 attached to the front panel),
is used to extend the addressing capability of the 29-key instant call panel. While JP1 is in
the A or C position, the panel functions normally with panel address p = 0 allowing access to
each of the 29 instant call buttons. While JP1 is in the B position, the top four keys of the
left-hand column are used to select one of four different panel addresses for the remaining 25
instant call keys. In this way, the small 29-key panel may access 100 different call stacks.
Possible uses include time of day personnel shift changes or selection between main and
standby transmitters (via the control relay programming).
Key 0x00 (top, left-hand instant call key) selects panel address p = 0 (this is the setting after
power-on); key 0x10 (next key down) selects panel address p = 1; key 0x20, selects panel
address p = 2; and key 0x30, selects panel address p = 3. One of the LEDs on these four keys
will illuminate to show the current panel address. In this special mode of operation, the
instant call key numbering varies and is similar to the numbering of the left half of the full-
sized auxiliary instant call panel. Note that if any instant call key is pending transmission
(LED is fully illuminated), the panel address cannot be changed. In addition, when a panel
address is changed, the LEDs that were previously blinking are fully extinguished. This
special feature is only available on the half-sized instant call panel on the encoder with
keypad (901-9019).
If jumper JP1 is changed while power is on, the encoder power must be cycled in order for
the encoder to recognize the changed setting.
JUMPER AND SWITCH SETTINGS
If the internal options of the Model 25 need to be changed in order to meet the needs of the
system, the encoder should be opened and the changes made prior to the encoder being
installed in the console. Table 7 lists the jumpers and the functions of their various positions.
The factory default settings are listed in parentheses in the “Functions” column.
