SS 4.2 Installation and Operation Manual
INSTALLATION
Serial Burst Mode Commands:
Burst mode allows a computer or ASCII terminal to control and interrogate the unit.
This section defines all burst mode commands. Each burst mode commands starts
with an asterisk (“*”). Next is a single decimal digit that corresponds to the unit (ID)
address 0-3. Following that are one or more ASCII characters specifying the com-
mand. No carriage-return or line-feed is required to terminate the command except
for those few commands of variable length, if the maximum length is not sent. 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 acknowledgements
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 repre-
sent values that should be substituted:
Glossary Of Command Notation:
Character Allowable
String Meaning Values
u Unit ID 0-3
ii Input Number 01-04
o Output Number 1-2
r Output Relay 1-4
o Open Collector 1-4
Set-up Commands:
*uMM - Open up Menu
*uC4x - Set RS-232 mode timings: x = 1, Turn ON RS-232 mode NO
delays on sending data. x = 0, Turn OFF RS-232 mode (delay for
RS-232 charge pump startup before sending response, unless ID = 0).
*uCCx - Set Serial Speed. See dipswitch SW13-3 & 4.
*uCEx - Enable Error and Good Responses - Where x = Y to enable and N
= 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.”
*uCDEF - Set factory defaults
*uCIIttt - Set “PIP” Programmable Pulse Stretcher Input Duration = ttt: 000
–> 255 hundredths of seconds (255 = 2.55 Seconds)
*uCIOiittt - Ignore, send OK
*uCLx - Lock Front Panel if x is “L”. Unlock Front Panel if x is “U”
*uCPR - Power up audio state: Restore audio from power up state
*uCPS - Power up audio state: Save power up state
*uCRtt - Set Relay Momentary Pulse Length – tt: 00-99 for 00 –> 9.9
Seconds
