Asynchronous Output Pause Command
This command allows the user to temporarily pause the asynchronous outputs on the given serial port.
When paused, both the ASCII and the 3 binary asynchronous output messages will temporarily stop
outputting from the device on the serial port for which this command is received. The state of the
asynchronous output register and the binary output configuration registers will not be changed when the
asynchronous outputs are paused. This command is useful when you want to send configuration
commands to the VN-100, but do not want to deal with the additional overhead of having to parse a
constant stream of asynchronous output messages while waiting for the response to your configuration
commands. It is also useful when you want to type commands to the device from a serial command
prompt. The below example commands demonstrate how to pause and resume asynchronous outputs.
Example Asynchronous Pause/Resume Commands
Example Command
Message
Pause Async Outputs
$VNASY,0*XX
Resume Async Outputs
$VNASY,1*XX

Binary Output Poll Command
This command allows you to poll the sensor measurements available in the binary output protocol.
Example Command Prompt Command
Example Command
Message
UART Command
$VNBOM,N*XX
Where N is 1-3 to selecte the appropriate binary
output register.
UART Response
Responds with requested binary packet.
To use the Binary Output Poll command you will first need to configure the desired output packet using
the Binary Output Register 1-3. If you wish only to poll this output, set the rate in the Binary Output
Register to 0. When you wish to poll the measurement send the command $VNBOM,N*XX where the
N is the number of the appropriate binary output register.
