Section 3 is a little different then the other sections because in steps 1 and 2 a CV value is
programmed instead of an address. Check the appropriate section in the manual to deter-
mine the CV value and use a switch address for that value.
In step 3 of section 3 the input and corresponding output are programmed with 16 sequen-
tial addresses. Input 1 and output 1 are
programmed with the issued switch
address. The rest of the input/outputs are
automatically programed with sequential
addresses. Switch type or sensor type
messages can be chosen.
4 Configuration Variables (CVs)
The SRC16 supports
Paged Mode Programming in Service Mode and Operations (Ops)
Mode
programming. To program in paged mode, connect the Track Power terminals to the
programming track. See diagram on the front page. When power is applied, LED 1 will
come on and LED 2 will flash when programming is successful. Some systems only apply
power during actual programming, so LED1 will only be on during that time. The SRC16
does not have built in feedback like a mobile decoder. Therefore, some systems may show a
“no decoder on track” error or “can not read CV”. However it still is programmed. To enter
normal operation, disconnect from the program track and connect as defined is section 5.
Ops mode or “programming on the main” is very convenient because you can try out the
CV changes almost immediately. In order to use this type of programming the ops mode
loco address must be set in CV1 (default is 1) and option 3 must be set in CV9.
This is a
loco address, so be careful when using this feature
. You can immediately start program-
ming in “Power On” ops mode without programming CV9 by holding down the Smart but-
ton just before power is turned on. When LED2 turns on release the button then wait until
LED1 turns off. This temporarily sets option 3 until power is turned off.
When using ops
mode to change CV values, the SRC16 does not recognize the new values of CV 1 - 13
until power is turned off and then back on.
Programming CV7 with a value of 1 will restart the SRC16 so power need not be cycled
when programming in “Power On” ops mode. This is the same as turning power off and
then back on. For programming with DecoderPro and other programming tips see Team
Digital’s web site.
Reset the SRC16 to factory defaults.
To “reset” the SRC16 to factory defaults, turn power on and wait until LED 1 turns off.
Then press the “Smart” button and continue to hold the button down (at least 16 seconds)
until both LED 1 & 2 are alternately flashing. Alternately, programming CV7 with 170 will
“reset” all CV’s to the factory default value. In page mode this may not work with some
systems as they do not keep power applied to the programming track long enough for all the
CVs to be programmed.
4.1 Output Address
These CVs determine the address of the outputs and how the output responds. Each output
has two CVs, an address and a type which includes the address adder, that makes up the
address. See section 7 for CV numbers. The type CV also contains the message type the
output responds to. That is, the output will turn on when a command is received when this
criteria is met. The following table shows the CV value to set the criteria.
To calculate the type CV value add up the selected values.

6.2 Routes
The SRC16 is well suited to handle routes in a yard. The following shows an example of
five routes using four switches. The route CV values were determined using the information
in sections 4.6 and 4.7. One very nice tool that makes custom programming much easier is
JMRI DecoderPro.
A route can be executed with an actual turnout (switch) address or a pseudo address of a
switch (not a physical switch). Program the top address of the route with the address you
want to execute the route.
