With the software-settable device “ID” feature enabled, the serial port output (transmit line) of the
actuator is disabled (high impedance). Thus, as many as ten actuators can be controlled from a single
host serial port for a temporary multidrop application. For permanent multidrop applications, the
RS-485 option is the factory-recomended solution. The table above describes and explains all the
commands available.
Using the Device ID Feature
Actuators are shipped from the factory with this feature disabled. When it’s enabled, the actuator
responds only to commands which begin with the correct ID prefix, allowing up to 10 actuators to be
controlled from one serial port. A single command can be broadcast to all actuators by using an
asterisk (*) as the command prefix.
Note: Any broadcast command which elicits a response from the
serial port (such as *VR or *ID1) will receive a combined and unintelligible response.
Serial Commands
CP Displays the current actuator position
CW Sends the actuator to Position A
CC Sends the actuator to Position B
GOn Sends the actuator to Position n, where n is A or B
TO Toggles the actuator to the opposite position
TT Toggles the actuator to the opposite position, waits a preset
delay time, then rotates back to the original position.
ID Displays the current device ID setting
IDn Sets the device ID to value n, from 0 to 9
NOTE: When the ID feature is enabled, all commands
to the device must be prefaced by the ID number.
Entering ID* disables this feature (discussed below.)
ID* Clears the ID variable
SB Displays the current baud rate
SBnnnn Sets the baud rate to 1200, 2400, 4800, 9600 (default), 14400,
19200, 28800, or 38400. The parity setting, number of data
bits, and number of stop bits cannot be changed. (See
section entitled Setting a New Baud Rate on the next page)
SOnnnn Turns off the position outputs after a delay, set in milliseconds
to the closest 5 ms interval, from 0 to 30,000 ms. The outputs
are always on (SO=0) by default.
SM Displays the current digital input mode (See section entitled
Digital Control of the Actuator, subhead Input Modes)
SMn Sets the digital input mode to Mode n, where n is 1 or 2
DT Displays the current delay time in milliseconds
DTn Sets the delay time from 0 to 65,000 milliseconds
NOTE: The total delay time equals n = 2 milliseconds
VR Displays the part number and date of the firmware
/? Displays list of valid commands
IN Starts a re-inialization sequence
