2.0 Setup DS78V Servo angle Adjustment mode:

The DS78V can be configured to conveniently drive all 8 servo outputs to the; T/

CW, Center or C/CCW servo angle positions for testing and installation.

1.  To go to Thrown/CW position: double click the RTS button with two quick 

presses and releases in less than 1 second. All servo arms will go to the T/CW 

position, and just the Green RTS led will blink rapidly.  To exit from adjust-

ing back to normal operation, double click the RTS button again.

2.  To go to servo Center position: double click the OPS button with two quick 

presses and releases in less than 1 second.  All servos will go to the center 

position, and just the Red OPS led will blink rapidly.  To exit from adjusting, 

double click the OPS button again.

3.  To go to Closed/CCW position: double click the ID button with two quick 

presses and releases in less than 1 second. All servos will go to the C/CCW 

position, and just the Green ID led will blink rapidly.  To exit from adjusting, 

double click the ID button again.

4.  You can enter Adjustment mode with just the 12V power hooked up, and do 

not need a command station, active LocoNet or a throttle to do these servo 

position adjustments.

3.0 Setup DS78V Ez-Routes:

The DS78V has 16 internal Routes with up to 8 SW# and T/C direction Entries 

each.  These can be set up by Ez-Routes method using the RTS button and switch 

commands sent from a LocoNet throttle, connected PC or DCC track.

1.  Press and hold the RTS button for about 3 seconds and the ID and OPSW 

LEDs will blink alternately to show one Route can be set up.  Release the 

RTS button. 

2.  Select a switch address on your throttle between 1 and 16 and issue the 

command direction for Closed.  This will now be the Route Number you are 

going to setup. Any previous Entries in this Route will now be replaced in 

following steps.

3.  Select the desired TOP Switch address between 1 and 2000 and issue a C or 

T direction command.  This SW# and direction  is that which will trigger this 

Route to be executed when seen by this DS78V

4.  Now enter up to 7 more SW# and direction T or C  for the other route Entries 

required.  The route entry ID/OPS LED will stop blinking indicating route is 

full/completed. 

5.  If you issue a SW# and direction twice consecutively that will also end route 

entry.

6.  If this DS78V does not have a LocoNet connection but operates from DCC 

Track power on the TKA/B terminals, then it will ignore Route Entries  that 

do not fall within the  DS78V's Base address and next 7 servos.

7.  Best practice is to set TOP SW#'s in each route in a unique "phantom" switch 

range e.g. 500 and above that do not control a physical switch. This will iden-

tify the issued switch is specifically a TOP or Route-start SW#.

8.  Ez-Routes do not have the ability to; read back , review or edit DS78V routes 

already set up.  For more powerful color graphics for comprehensive DS78V 

Route review and editing consider using a DT602 as noted in section 6.0

9.  The green RTS LED will be steady ON if there are any routes programmed.
