Switch Configuration
A set of configuration jumpers has been provided for panel switches SW1 and SW2. These configuration
jumpers enable switches SW1 or SW2 to be set as a button on the keypad matrix or one of the
programmable inputs IN1 or IN2.
SW1
Configuration jumpers labeled R1-R4 and C1-C5 (on P14 and P29) enable switch SW1 to be set as a
single button of the keypad matrix. For example: to configure switch SW1 as keypad button 5, install the
jumpers on row R2 and column C2. Two configuration jumpers labeled C_GND and IN1 (on P18 and
P23) enable switch SW1 to be set as programmable input IN1. To set switch SW1 as input IN1, install
the jumpers on C_GND and IN1.
N OTE : The function of input IN1 must be programmed in the central cabinet. Refer to the “Inputs”
section of the central cabinet instruction manual for instructions on how to program this input. Also, the
footswitch input shares the programmable input IN1 with SW1. Either the footswitch can use
programmable input IN1 or SW1, but not both.
SW2
Configuration jumpers labeled R1-R4 and C1-C5 (on P13 and P1) enable switch SW2 to be set as a single
button of the keypad matrix. For example: to configure switch SW2 as keypad button 9, install the
jumpers on row R3 and column C3. Two configuration jumpers labeled C_GND and IN2 (on P7 and
P12) enable switch SW2 to be set as programmable input IN2. To set switch SW2 as input IN2, install
the jumpers on C_GND and IN2.
N OTE : The function of input IN2 must be programmed in the central cabinet. Refer to the “Inputs”
section of the central cabinet instructional manual for instructions on how to program this input.
