the strain relief cable fitting for approximately four inches.
Strip the insulation from the two wires back ¼” and secure
the wires in the terminal strip position marked SE.
2-4A. A Knockout (K.O.) switch may be wired to the Tx
terminal strip marked KO-1 and KO-2. Either normally
open or normally closed switches may be used.
2-5. Place the two AA Lithium batteries in their holders in
the proper direction, paying attention to the (+) and (-) ends.
2-6. Tuck the wires connected to the SE terminal block neatly
between the batteries and pull the excess wire back
through the strain relief.
6-A. Re-seat the PCB and securely tighten the cable fitting.
2-7. Set the Termination Type switch to either 10K resistive
or 9.1v Diode. (see Appendix) This selection must match
the Termination type in the Monitored Device.
2-8. Address Switches
Set the Group(red) and Address (blue) switches to
the desired position. (Note the settings for reference when
setting up the Receiver)
If the Group switch is set to 0, the address switch may be
