DR4024 DIGISERVO (v1.31)

Quick start
By following these steps you can immediately start using the decoder as a 4-channel servo decoder with 4 extra
switching outputs.
Giving the module an address
The DR4024 module requires an address in order to be able to communicate with your control unit.
By default, the module is delivered with the address ‘1’ and is set up as a
servo decoder
in
DCC format
.
Step 1:
Connect both the POWER + SIGNAL to the rails or rails (track) output on your control unit at
the same time.
Step 2:
Set your control unit to the starting address that you want to give the module.
Step 3:
Press and hold the programming switch on the module until the red LED remains lit.
Step 4:
Now switch to the address you entered on your control unit.
Step 5:
If the module is connected correctly, the LED will turn off after you switch to the desired
address
Step 6:
The first servo output (OUT1) has now been given the address you chose. All subsequent servo
outputs are given address one number higher.
Example:
You programmed the module to address 56, meaning
S1
has been given address 56,
S2
no. 57,
S3
no. 58,
S4
no. 59,
OUT1
no. 60,
OUT2
no. 61,
OUT3
no. 62 and
OUT4
no. 63.
Because the decoder is multi-protocol and supports DCC and Marklin Motorola, choosing an address also se-
lects the protocol. When receiving a switching command, as in the above steps, the decoder identifies which
protocol is used, and stores this in its memory.
IMPORTANT!
In
DCC
mode, you can choose any start address you like and the module will automatically assign successive
outputs a higher address in increments of 1. The
Motorola
protocol works with groups of 8 numbers. You can-
not choose a mid-range address as the start address. EXAMPLE: Address 1-8 or 9-16 or 17-24 etc.
Returning the module to factory settings using POM programming
Follow the steps below to set the module back to factory settings using POM programming.
Step 1 :
Connect the
signal
input on the decoder to the rails output of your control unit.
Step
2 :
Ensure the module is supplied with voltage via the power input on the module.
(You can also connect the
power
and
signal
inputs to each other)
Step
3 :
Set your control unit to POM programming mode
(more information about POM can be found in your control unit’s manual)
Step
5 :
Choose
loc address
9999
on your control unit
Step
6 :
Press the switch on the module once so that the red LED comes on
Step
7 :
Program decimal value 8 at CV8
Step
8 :
Press the switch on the module once so that the LED goes out
Step
9 :
It is important during a RESET that the module is not supplied with a voltage for a short time.
To do this, disconnect both the power and signal inputs on the decoder and wait 3 to 5 seconds.
Step
10:
The power can now be reconnected and the module will be back to its factory settings.
CAREFUL! The decoder now has address 1 again.
