4.6 Input Control
These CVs determine what action the inputs will have when activated. There are three CVs
for each input. An address, type and transition CV. See section 7 for CV numbers. If an
address greater than 255 is needed then use the address adder. The address adder value rep-
resents a number that is added to the address value to give the ‘actual’ address.
There are 16 physical input terminals. They can each be programmed to operate independ-
ently or to operate as a pair in a group (default). They are not linked or connected to the
outputs an any way except by a common address and type.
In order for an input to cause an action, a transition must be selected. Each input has a ‘pul-
lup’ resistor connected to 5 volts, so the input is normally at 5 volts. An input transition is
when the voltage on an input goes from high to low (falling edge) or from low to high (ris-
ing edge). For example, if a push button is connected to an input and ground, when it is
pressed the input is grounded. This causes a high to low transition. When the button is re-
leased this causes a low to high transition.
To set addresses for input groups see “Smart” Programming for easier programming.
Route execution feature requires version 16.
4.7
Route Execute Address
These CVs determine the top or execute address of a route. See section 7 for CV numbers.
Each top address is completely independent of an input or output address. A route is exe-
cuted when a turnout (switch) command from any source including those from the SRC16,
throttles or computers matches the top address and switch state for that route. When a route
is executed, turnout commands are sent for each cell containing an address. Optionally, a
route can be executed by a block sensor message. In this way several turnouts can auto-
matically be alined went a block becomes occupied.
4.8
Route Cell Address
These CVs determine the address in a route cell. See section 7 for CV numbers. When a
route is executed all cell addresses are sent one at a time. For all addresses in a route to be
sent there must be no empty cells between cells with addresses.
4.9
Send Address Delay
CV11 - Send address time delay, value 0 to 255.
This CV determines the time delay the SRC16 waits before sending the next address in a
route. Some switch machine drivers require a time delay between switch activation.
The delay is the CV11 value x 0.25 seconds.
4.10 Operations Mode Loco Address
CV1 - Ops mode address, a value of 1 to 127. Default is one (1).
This CV sets the operations mode program address. Program the SRC16 just like you
would a loco in ops mode. This is a loco 2 digit address and therefore must be unique
among locomotive addresses. Option 3 must be enabled to use this address for program-
ming on the main.
