6.0 Advanced DT602 based DS78V configuration
To perform these advanced features, the DT602 will need to be user updated to
SubVersion 0.5 or higher, or a July 2021 or later IPL - see www.digitrax.com.
6.1 Detecting all DS78V's and setting Base addresses:
On
an updated DT602 plugged into LocoNet, press the; Menu>3>4 keys to enter the
Route Editor menu. If any DS78V is plugged into LocoNet, the DT602 will beep
after about one second and show "DS7x" routes at the D soft key position.
1. Press the D soft key to now enter the "Selecting DS7X device:" screen as
shown below. This example DT602 screen shows four DS78V devices detect-
ed on LocoNet, with their; Base SW address, active SW address count# and
unique device serial numbers (SN or SerNo).
2. The lowest DS78V Base address detected and sorted is SW0001, with 8
outputs and SN 9122. This is displayed in GREEN to indicate that it does
NOT conflict with the 2nd DS78V SN 3122 at Base address 9. This is true
because the next free address is SW1+8 or SW0009, that 2nd DS78V SN
3122 is set at or above. You can use the LH encoder knob to scroll up and
down through the detected DS78V devices, with an underline showing the
selected DS78V.
3. The 3rd DS78V shown at Base SW17 uses
16# SW outputs, since it is configured by
OPSW's to operate 8 semaphore SW pairs
instead of 8 T/C SW turnout controls.
4. The 4th DS78V at Base Sw25 overlaps the
3rd DS78V, and so the 3rd SW base is dis-
played in RED text, since SW17+16 would
require the 4th DS78V SN9945 to have
a base address of at least Sw33 to avoid
SW# overlaps. It shows just SW25.
5. Rotate the DT602 LH encoder knob to
underline the 4th DS78V line entry after
the RED collision marked 3rd DS78V.
6. Press the numbers 3 then 3 then press the
soft key "Chng Adr" , A. The 4th DS78V
will change to Base SW33. The 3rd DS78V
info now shows all GREEN because there
are now no SW overlaps of DS7x devices
after it. This "Chng Adr" to 33 for the 4th DS78V Base SW# just cleared the
3rd DS78V's active SW range (minimum is: 17+16 =33), fixing the problem.
7. To identify the actual underlined fourth physical DS78V on the layout; press
the F soft key "Ident" and just this DS78V will blink its ID/OPS/RTS leds for
3 seconds. Press "X" to exit any DT602 advanced mode.
8. This advanced DT602 capability allows you to setup all DS7x family devices,
like the DS78V and DS74, in position on a LocoNet layout, quickly and con-
veniently, even if all devices are initially at factory-default Base SW1.
9. If you are using other types of non-DS7x family Switch control decoders, you
will have to note their active SW addresses and manually ensure the DS78V's
are configured to not overlap these.
