4.3 Power On Output State
CV12 - Power on state for output groups 1 to 4, a value from 1 to 170
CV13 - Power on state for output groups 5 to 8, a value from 1 to 170
These CVs determine the state of each output group at power on. Decoder configuration
option 1 or option 2 has to be enabled for this these CVs to function. You only need to pro-
gram these CVs if option 2 is enabled. If option 1 is enabled, the SRC16 automatically pro-
grams them. These tables only apply if the SRC16 outputs are configured in groups.

Example: CV12 = 1 + 4 + 32 + 64 = 101, throw output group 1, throw output group 2, close
output group 3 and throw output group 4
Example: CV13 = 2 + 8 + 16 + 64 = 90, close output group 5, close output group 6, throw

4.4 Decoder Configuration
CV9 - Configuration.
This CV determines the configuration which consists of several options.
Option 1 - Memory. The SRC8 will remember the output state at power off and at power on
the outputs will be set to the same state.
Option 2 - Default output state. At power on each output will be set to the state as deter-
mined by CV12 and CV13. You must program CV12 and CV13 to the desired state at
power on. Option 2 disables option 1. See section 4.3.
Option 3 - Ops Mode Programming. Allows Operations mode (On the Main) programming
using a Loco address to be enabled all the time. See section 4.10.
Option 4 - DCC to bus gateway. Allows DCC switch command packets to be put the serial
bus. Any device connected to the bus will have access to these DCC commands. Requires
option 5.
Option 5 - Serial Bus communication. Allows the SRC16 to communication with devices
connected to the serial bus.
Option 6 - DCC control. Allows the SRC16 to receive instructions from DCC (track).

this feature.
Option 7 - Output lockout. Allows an input, when grounded, to keep the respective output
from changing. Intended for use when inputs and outputs are configured as groups. This is
address independent.
Option 8 - Common cathode LEDs. Allows common cathode connection of LEDs to the
outputs.
using flat ribbon cable Insulation Displacement (IDC) and connectors from Jameco. The
mating connector is #138377. 10 ft of gray flat ribbon cable is #643794. 10 ft of multicolor
flat ribbon cable is #639672. See the diagram on the front page for connector location.
Warning:
Do not connect the power supply ground (minus) to the ground (minus) pin of
the 10 pin IDC connector. Do not connect any outputs together or to other SRC16 outputs.

Voltage to
pin 6 based
on resisitor
Voltage applied to pin 6 of the two output connectors can be changed by the position of the
shorting bar. The standard position provides 5 volts when the SRC16 is driving LEDs or
other low current 5 volt devices. See section 5.3.
The other positions provide a higher voltage for use when Team Digital MotoDs are con-
nected to the outputs. A MotoD is a satellite motor driver that is controlled by the SRC16.
Up to four MotoDs can be controlled be the SRC16.
Caution: Do NOT move the shorting bar from the factory position unless MotoDs are
being used or the SRC16 may be damaged!
