HANDSET DIAGRAMS

These schematic diagrams outline different handset configurations should you decide to construct

your own handset. The standard configuration of the 851HS is shown in figure 2. Variations of

this configuration are shown in figure 3. When constructing your own handset be sure to follow

standard electronics soldering practices. Always use a clean soldering iron and NEVER use acid

core solder or acid flux. Inspect your work to ensure solder joints are clean, smooth and shiny

and that connections go to where they are intended.

Part values shown are not "carved in stone". Feel free to experiment with these values. The only

caveat is that the "speed" control's value must not be below 5KOhm or above 50KOhm and it

must also be a "linear taper" potentiometer.

CONNECTIONS TO TERMINALS

1 - speed control voltage input

2 - direction control voltage input

3 -12VDC handset supply

4 - handset ground

5 - AC/DC supply terminal

6 - AC/DC supply terminal

7 - track voltage

8 - track voltage

Note - Terminals are numbered on the

bottom of the PCB assembly
