Set Device ID
Description: This command is used to configure the Device ID of the DVM. The Device ID is
typically used to individually address DVM’s that share the same control line.
Command Bytes: nID
Parameters: n is a numeric value between 0 and 126 that represents the Device ID
Message Response: R
Examples: Set the Device ID to 4: 4ID
Software Reset
Description: This command will reset the DVM, just as if the power were cycled.
Command Bytes: XX
Parameters: None
Message Response: None (System will immediately reset without responding)
Send Serial String
Description: This command causes the DVM to send a user-defined serial string out of its RS-232
control port. This can be handy for using the DVM to activate other RS-232 controlled
devices (ie. Turning on Displays, Projectors, etc.)
Command Bytes: <serial string code>SS
Parameters: <serial string code> is a string of coded ASCII characters that tell the DVM how to
assemble the actual serial message.
Comments: The serial string code gives you the capability to assemble any kind of serial
message, even those containing non-displayable ASCII characters (ie. Carriage
Return, Line Feed, etc.). To include alpha-numeric ASCII characters in your serial
string, you simply wrap them in quotation marks. To send hexadecimal bytes, you
simply precede the Hexadecimal value with the letter ‘h’. To understand exactly how
this is done, see the examples below.
Message Response: R
Examples: Send the ASCII string “Start”: “Start”SS
Send the ASCII string “Start” terminated by a CR: “Start”h0dSS
Send the hexadecimal characters 0x01 0x02 0x03: h01h02h03SS
