SS 16.4 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 command 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
command. 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 acknowl-
edgements 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 char-
acters represent values that should be substituted:
Glossary Of Command Notation:
Character String Meaning Allowable Values
u Unit ID 0-3
ii Input Number 01-16
o Output Number 1,2,3,4
or Output Relay 1-8
oo Open Collectors 01-16
Set-up Commands:
*uC4x - Set RS-232/RS-485 mode timings:
x = 1, Turn ON RS-232/RS-485 mode NO delays on sending data.
x = 0, Turn OFF RS-232/RS-485 mode (delay for RS-232 charge pump
startup before sending response, unless ID = 0).
*uCCx - Ignore, set by switches
*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.”
*CDEF - Reset to factory defaults
*uCIIttt - Set “PIP” Programmable Pulse Stretcher Input Duration = ttt: 000 – 255
Off to 2.55 Seconds.
*uCIOiittt - Ignore, send OK
*uCLx - Lock Front Panel if x is “L”. Unlock Front Panel if x is “U”
*uCPC - Power up audio state is set by menu or burst command. *CPS
(default)
*uCPL - Power up audio state, last source(s) selected
*uCPR - Set audio to power up state
*uCPS - Save current audio state as power up state
*uCRtt - Set Relay Momentary Pulse Length – tt:00-99 for 00 – 9.9 Seconds
*uCSAtttt - Set silence sensor time delay to tttt seconds (0002 – 9999), 0000
= OFF
*uCSBtttt - Set silence sensor restore delay to tttt seconds (0002 – 9999), 0000
= OFF
