6.2 Program SE74 CVs on LocoNet:
As for section 2.0, with a
DT602, press the; Menu>2>1 keys to enter Operations Mode programming.
1.
Press the "SWITCH" soft key F to enter
the "
Ops Switch"
mode programming
screen as shown adjacent. This example
screen shows CV11 selected for an SE74
with
BASE address of SW1
.
2. Use the LH and RH encoder knobs to
select the SW#/ADR of the SE74 to
modify a CV on. An SE74's CV11 to
CV16 access the 48 OPSW bit settings.
3. For example; press the "CVDATA" soft
key at CV11 to change to CV data entry,
press the number 1 then press "WRITE".
This now configures the 8 OPSW bits of
CV11 to 1, forcing this SE74 to change to
slow motion turnout control.
4.
Be careful changing the values in
CV11,12,13,14,15 and CV16 since the 8
bit data number 0-255 in these CV's ac
-
tually each control 8 individual OPSW bits. OPSW1 is ls bit of CV11, through
OPSW8, as ms bit of CV11.
5. The DT602 does not indicate to the SE74 when programming is complete.
After
finishing
CV changes, best practice is to POWER cycle the SE74 to save
changes. Alternately, you can WRITE CV7 to 00 to restart that SE74.
