1.0 DS78V Quick Start - Eight servos, Thrown/Closed

The DS78V is simple to install and begin using on your LocoNet based layout.
1. Figure 1 shows the recommended connections to operate the DS78V on
a LocoNet layout and to control up to eight mounted servos, like Digitrax
DSXSV9's.
2. Connect a PS14 or similar DC 12V power supply to the DS78V via the DC
power jack. When powered the green ID LED should light and will briefly
wink OFF every 2 secs as a product 'heartbeat' showing the DS78V is opera-
tional. Alternatively, power from DCC feeder wires to the TKA/B terminals.
3. Plug in an active LocoNet to a DS78V RJ12 connector. The red OPS LED
will light up showing connection. Any good LocoNet message seen will cause
the DS78V OPS LED to blink OFF briefly. With no LocoNet the unit will
respond to switch commands from a DCC track connection.
4. Press and hold down the ID button for about 3 seconds until the RTS and
OPS LEDs blink alternately, then release the ID button.
5. From your system send a SW command to set the Base Board address at this
SW#. The OPS and RTS LEDs will stop blinking showing the DS78V has set
the unit's Base SW# to the SW# you just sent, which is for Servo1 control.
6. Plug in the servo 3pin connector(s) to the outputs you wish to control. The
connector brown wire will be closest to the DS78V beige case top.
7. Operate turnouts with a SW# and direction Thrown (T)/Clockwise(CW) or
Closed(C)/Counter-Clockwise(CCW) settings at the; Base SW#, or the next
consecutive 7 SW#'s now in use by this DS78V.
That's all that's required for installation of your DS78V on LocoNet!
