UNIT

F1 - LCD DISPLAY - This displays the selected

DAD860 unit number, the selected parameter, and

its value.

F2 - UP Button - When in program mode, this

button scrolls upward through the available param-

eter values. When not in the program mode, this

button will have no effect.

F3 - LEFT Button - This button scrolls counterclock-

wise through the available parameters for the

selected unit.

F4 - UNIT Button - This button scrolls in numeric

order through the available DAD860 units. When a

unit is selected, its amber LINK LED will flash

continuously. While the LINK light is flashing, the

LCD will display the selected unit number and the

signal to noise ratio of the received signal or "NO

LOCK" if no signal is being received. After a unit is

selected, the controller backlight and the selected

unit's amber LINK light will extinguish after approxi-

mately 40 seconds if there are no other control

inputs.

F5 - ENTER Button- Pressing this button for two

seconds will enter the program mode for the se-

lected DAD860. This is indicated by the LCD

flashing on and off at an interval of approximately

one second. Once in the program mode, pressing

this button will save the selected parameter value and

will then scroll clockwise to the next parameter, while

remaining in the program mode. When not in program

mode, it will scroll clockwise through available

parameters without saving any data. When in program

mode, it is also used to access secondary menus,

progress through secondary menu trees and to store

the value selections in these menus.

R1 - COMM Connector - This connector provides a

means of connecting the controller to each of the

DAD860 units. A supplied cable is attached to this

connector the other end of which is terminated in

ten numbered three conductor connectors. The

connector number corresponds to the unit number

of the DAD860 to which it is connected.

R2 - POWER Connector - This three conductor

connector connects to one of the twelve cables from

the PSM121 power supply to supply power for the

programmer.

POWER SUPPLY

The DAD860 requires multiple power supply voltages

that are all obtained from the Drake model PSM121

power supply module. The PSM121 mounts in the

RMM12 rack tray along with one to twelve DAD860

decoders (or other similar Drake models such as

VMM600 series modulators). The PSM121 provides

+5V, +12V and GND connections to each unit.

The PSM121 operates over a wide range of AC input

voltages from 90 VAC to 240 VAC, 50/60 Hz, and has

an 3 wire line cord receptacle. Power consumption

from the AC line will be around 60 W with twelve

DAD860 decoders installed. In many cases, the

power will be below this level.
