Serial Communication The DVS 204 can be remotely controlled via a host computer or other device (such as a control system) attached to the rear panel Remote connector. The control device (host) can use either Extron’s Simple Instruction Set (SIS) commands or the graphical control program for Windows. The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.
Using the command/response tables The command/response tables on the next page list valid command ASCII codes, the scaler’s responses to the host, and a description of the command’s function or the results of executing the command. Upper and lower case characters may be used interchangeably in the command field. The ASCII to HEX conversion table at left is for use with the command/response tables.
