pect "color", "flashing color" and then head DARK. DARK provides a choice

for "approach lighting".

Press the number keys to choose another head# to change. In DCC Aspect

control mode the SE74 base Head1# is set as the same number

as the Board base address used by the turnouts. Factory default

Head1 = 253, through to Head16 = 268.

Press the C soft key (Switch) to return the DT602 to system Switch control

for turnouts instead of Signal DCC Aspect control mode.

The nine default DCC Aspect commands define RED/YEL/GREEN or LU-

NAR and their Flashing versions, as well as overall head DARK. The 'white'

LUNAR lamp is an alternate to the 3 lamp colors on the same head number.

If you want a Lunar lamp on the Head to display at the Head address at the

same time as one of the 3 color lamps, then configure the SE74 with OPSW41

=C to set the Lunar lamp setting Persistent, independent of the color lamps.

10. Head 2048 sets an Aspect mode Broadcast to all heads of SE74's using DCC

Aspect control.

3.0 Setup SE74 Ez-Routes:

The SE74 has 8 internal Routes with up to 8 SW# and T/C direction Entries

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

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

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 SE74

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 when

route is full/completed.

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

entry for that Route Number.

If this SE74 does not have a LocoNet connection but operates from DCC

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

Entries that do not fall within the SE74's Base address and next 4 outputs.

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 or edit SE74 routes

already set up. For more powerful color graphics for comprehensive SE74

Route review and editing using a DT602 see section 6.2

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