SRC-16 Installation and Operation Manual
INSTALLATION
Serial Burst Mode 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 03. Following are one or more ASCII characters specifying the
command. A carriagereturn is required to terminate each command. If the
command requested a response, the response will consist of an upper case S,
followed by the unit address, and then the specific 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 exactly as it should be sent, except that lower case characters represent
values that should be substituted:
Glossary of Command Notation
Character String Meaning Allowable Values
u Unit ID 03
ii Input Number 0116
oo Relay Number 0116
Setup Commands
*uCCx Set Serial Speed. x = 0: 2400 1: 9600 2: 4800 3: 38400
*uCEx Enable Error and Good Responses Where x = Y to enable and N = disable.
In this mode, when a command is sent, the unit will reply (possibly before receiving
the entire command) with “EEE.” If the command is sent correctly, the unit will
reply with “RRR.”
Relay Control Commands
*uORrrL Latch Relay rr, relay number
*uORrrF Unlatch Relay rr, relay number
*uORrrPtt Pulse Relay rr, relay number 01à16.
Pulse Length tt: 0099 corresponds to 00 9.9 Seconds.
Information Retrieval Commands
*POLL Respond with unit (ID) address in appropriate time slot. If there are multi-
ple units on the line, each will respond with a different delay after receipt of
this command.
*uSPii Send status of input ii. Response is SuP,ii,x where x is 1 if the corresponding
input is high, 0 otherwise.
*uSPA Send status of all inputs. Response is SuP,A,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x
<CR><LF > where input 1 is first and input 16 is last. x is 1 if the corre-
sponding input is high, 0 otherwise.
*uSR Send status of all OUTPUTS. Response is:
SuA,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x <CR><LF>
*uU – Send Unit Information :<name(SRC-16)><version n.nn><cr><lf>
