SRC-32 Installation and Operation Manual
INSTALLATION
DIP 8 = (ON)
Invert sense of LCD display of inputs. A closed contact will display
as a “1” and an open as a “0”.
(OFF)
A closed contact will display as a “0” and an
open as a “1”.
NOTE: After changing DIP settings, be sure to press the reset button or recy-
cle the power.
SRC-32 ASCII 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. Dipswitch 5 must be off for
the ASCII commands to be received. Each burst mode command starts with an
asterisk (*). Next is a single decimal digit that corresponds to the unit (ID) address
0-3. Following are one or more ASCII characters specifying the command. A car-
riage-return 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 com-
mands 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 sub-
stituted:
SRC-32 ASCII Commands:
*uC4x-
Set RS-232/RS-422/485 mode timings: x = 1, Turn ON
RS-232/RS-422/485 mode NO delays on sending data. x = 0, Turn OFF
RS-232/RS-422/485 mode (delay for the RS-232 charge pump startup
before sending response).
*uCCx-
Set Serial Speed. x = 0: 2400 1: 9600 2: 19200 3: 38400
*uCEx -
Enable Error and Good Responses- Where x = Y to enable and x = N to
disable. In this mode, when a command is sent that is in error, the unit
will reply (possibly before receiving the entire command) with “EEE.” If
the command is sent correctly, the unit will reply with “RRR.”
*uCAxxx…x - Load AT command string for modem init. (future feature)
*uCTxxx…x - Load Telephone number for modem to dial if set to master in modem
mode. (Future feature
)
