DIP Switch Functions
Groups 6 & 7
The DIP switch functions on the TC8116 apply individually to their respective
"A" or "B" board. To activate the function, slide the appropriate switch to the
On (Down or Right) position.
RMTLB: Remote Loopback.
This switch (SW1) initiates the Remote
Loopback function. The composite optic signal is received from optic "RxA" (or
"RxB) and decoded, then looped back to optic "TxA" (or "TxB) for diagnostic
testing.
LOCLB: Local Loopback.
This switch (SW2) initiates the Local Loopback
function. The electrical signal is received and decoded, then looped back to the
transmit pins for diagnostic testing.
SIG GEN: Signal Generator.
This switch (SW3) initiates the built-in signal
generator function. The unit will generate a pulse signal to emulate an electrical
transmission signal. By verifying the "Rx" channel LEDs on the remote unit, the
user may confirm that the local unit's signal is being received.
DIS ALM: Disable Alarm.
This switch (SW4) disables the alarm relay and
buzzer during alarm conditions.
