2.8.
Setting Access Code (for units with no external code plug only)
The access code is set at the factory and should not be changed unless absolutely necessary. If a
spare transmitter unit is used, the receiver unit access code should be changed to match the access
code of the spare transmitter unit. For Part 15 systems the access codes are printed on a white
label on the outside of any transmitter and may be matched to “A” and “B” on the receiver CPU
Board without having to open the transmitter housing.
Switch SW2 (B) in the transmitter must match switch S4 (B) on the receiver CPU Board and
switch SW1 (A) in the transmitter must match switch S5 (A) on the CPU Board.
For Part 90 systems the 12 bit access code is assigned starting with position A1 through A8 then
B1 through B4. For 8 bit access codes, switch B is not used. See system documentation for the
Part 90 access code.
If the codes do not match, you will get an error light DS9 on the CPU Board while transmitting.
2.9. Programming Switches
The programming switches in SW3 (C) controls the following features:
(These only apply to units
originally programmed to utilize these features).
External Code Plug Enable – Switch SW3 (C) – position 1 turn “ON” to enable external code
plug.
Processor to send Software ID to PC Enable – Switch SW3 (C) – position 6 turn “ON” to allow
special software to be enabled to read the software ID. (Only Magnetek authorized personnel has
the ability to view.)
Tilt Switch Enable – Switch SW3 (C) – position 7 turn “ON” to enable the Tilt Switch.
Time-Out-Timer Disable – Switch SW3 (C) – position 8 turn “ON” to disable the transmitter
time-out timer.
2.10. To Check Data.
1). For data input use the Data pin on the RF Module.
2). Use the RF SW pin on the RF Module for an External Trigger input.
3). Use test point TP2, for Ground.
2.11. Battery Monitor
Set to 5.8 Volts by R6 and R8 (not adjustable.)
2.12. Analog Voltage Reference
V+ (TP3) factory is adjusted with RPOT2. V- (TP1) factory is adjusted with RPOT2.
2.13. Transmit LED
This red LED flashes rapidly during transmit, slowly when unit is ON, and turns out when battery
is low.
