2.0 DS74 Quick Start - Slow-motion motors:

Figure 2 shows the DS74 wired for four 2-wire slow-motion motors. Using

these Figure 2 connections, follow steps 2 to 5 of prior Solenoid section 1.0.

Press and hold the OPS button for about 3 seconds until the green ID and

RTS LEDs blink alternately. Release the OPS button. The DS74 is now setup

to configure Option Switch (OPSW) 1 to 40 by sending the required SW# as

Closed or Thrown to setup an option.

Issue a SW#1 Closed command. This sets OPSW1 to Closed (C) From

factory defaults this will configure for Slow Motion switch outputs.

Note: If the DS74 is not at factory defaults, also set Switch#2 =T,

Switch#3=T and Switch#4=T. See Options section 4.0.

Press and hold OPS button for about 3 seconds to now exit OPSW setup.

2.1 DS74 Quick Start - Lamps:

R/G leads as the negative connection and P+/P2+ for positive. From defaults, set

OPSW1=C and OPSW3=C to enable Lamp mode. The DS74 now responds to 8

SW#'s; with C = lamp ON and T = lamp OFF for 8 R/G output lines. LED lamps

require current setting resistors and correct polarity connection.

3.0 Setup DS74 Ez-Routes:

The DS74 has 8 internal Routes with up to 8 switch# and T/C direction Entries

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

mands from a LocoNet throttle or connected PC.

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.

Select a switch address on your throttle between 1 and 8 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.

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 DS74

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.

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

entry.

If this DS74 does not have a LocoNet connection but operates from DCC

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

do not fall within the DS74's Base address and next 3 SW addresses.

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#.

Ez-Routes do not have the ability to read back , review and edit DS74 routes

already set up. For more powerful color graphics for comprehensive DS74

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