13.5 Reading Back CV Values Programmed
Your DCS100 and DT400 together can read back the configuration variable
values programmed into your decoders. Since you must use the programming
track for this, infrared and radio throttles must be plugged in to LocoNet to
read back CV & their values. Systems with a DB150 command station are not
able to read back CV Values programmed into decoders.
To read back CV values:
1. Place the decoder equipped locomotive you want to program on the
programming track. You can also do an ops mode read back with
Digitrax transponding decoders if you have a LocoNet device that
allows ops mode read back plugged in to LocoNet.
2. Enter Program Mode by pressing the PROG Key
to enter pro-
gramming mode. The display will show the last CV and CV Value
you programmed.
3. Select the programming mode you wish to use by pressing the PROG
Key
until the method you want appears in the Mode Indicator.
You can read back in P

modes with the following restric-

Physical Register Mode can only read CV01-CV08.
You should not rely on values in the display for CVs
above 08 when reading back in physical register mode.

Operations Mode readback can only be used with Digitrax decoders
that are capable of ops mode read back when there is a device
attached to LocoNet that supports ops mode read back. Digitrax
transponding decoders and DCS100 would allow ops mode read-
back.

To read back the CV value programmed for the two digit address
(CV01), use the L Throttle knob to dial up Ad02 on the left side of
the text area and then.press the DISP Key
. The text area will
show Ad2 =rd followed by a flashing box. When the read back is
finished, the CV value (the 2 digit address) will be displayed on the
right side of the text area.
5.
To read back the four digit address that is programmed into the
decoder
use the L Throttle knob to dial up Ad02 on the left side of
the text area, then press the R throttle knob to change to Ad4. The
