ALARM OUTPUT METHOD SETTING
There are two alarm output methods: NO and NC. NO means
normal state is open circuit, the circuit will be closed when an
alarm comes in. NC means normal close circuit.
When choosing pins 1&2 in JP6 and JP7,the alarm output
state is NC. When choosing pins 2&3 in JP6 and JP7, the
alarm output state is NO. Factory default is NO. (Refer to the
following picture):
RESISTOR JUMPER SETTING
RS485 bus needs two 120 Ohm resistors at both ends. Set on
the 120 Ohm resistors of the two devices (keyboard or dome)
in the farthest distance on RS485 bus. Default setting is OFF.
When connecting pins 1&2 in JP1, the 120 Ohms termination
resistor is connected. When connecting pins 2&3 in JP1, the
termination resistor is unconnected.
