SRC-16 Plus Installation and Operation Manual
SETUP
Data Operation Mode (Mode 7)
This mode allows the SRC-16 Plus to be used with a wide variety of serial devices
by allowing the user to define custom relay control strings and custom input strings.
These strings are set in the Data Programming Mode and are used in the Data
Operation Mode.
When you have finished programming data strings, exit program mode and set DIP
6,7,8 ON. The data programmed for the various inputs will now be transmitted when
the corresponding input is closed. Relays will pulse when received data packet
matches the data programmed for that relay.
When the “?” is received it be treated as a wildcard and will match whatever is in
stored memory.
If a “#” character is received in a data packet the an “@” will be accepted as the end
of packet character instead of a carriage return.
ASCII Burst Commands
The burst mode allows a computer or ASCII terminal to control and interrogate the
unit. This section defines all burst mode commands.
Each burst mode command starts with an asterisk (*). Next is a single decimal digit
that corresponds to the unit (ID) address 0-3. Following is or more ASCII charac-
ter(s) specifying the command. A carriage return is required to terminate each com-
mand. If the command requires a response, the response will consist of an upper case
“S”, followed by the unit address number, and then the specific command response.
If acknowledgments are enabled, successful commands are responded to with
“RRR” while errors get an “EEE” response.
The syntax of each command is given below. The syntax shows the command exact-
ly as it should be sent, except that lower case characters represent values that must
be substituted by the user.

Setup Commands
*uCCx - Set Serial Baud Rate. x = 0: 2,400 1: 9,600 2: 19,200 3: 38,400 4: 4,800
Command Example: *0CC3 will set the serial baud rate to 38,400
*uCEx – Enable or disable command success/error responses, where x = Y to enable
and N = disable. In this mode, when a command is sent, the unit will reply (possi-
bly before receiving the entire command) with “EEE.” If the command is sent cor-
rectly, the unit will reply with “RRR.”
Command Example: *0CEY enables command success/error responses.
