Introduction to SIS

The MLA VC10 Plus accepts SIS commands from a control device connected to the RS-232

3-pin captive screw connector on the rear panel or to the female mini B USB port on the

front panel.

NOTES: • The wiring in the RS-232 cables crosses over so that the Tx of one device

connects to the Rx of the other and vice versa.

• Neither port takes precedence over the other. Commands are always

processed in the order that they are received.

The RS-232 protocol is 9600 baud, 8 data bit, 1 stop bit, and no parity.

SIS commands consist of a string (one or more characters per command eld). Unless

otherwise stated, upper and lower case characters may be used interchangeably.

When a command is valid, the MLA executes that command and sends a response to

the host device. Commands do not require any special characters to begin or end the

command string. Each response from the MLA VC10 Plus ends with a carriage return and

a line feed (CR/LF =

]), which signals the end of the response character string.

When the MLA VC10 Plus is rst switched on, it sends the message:

where 60-1090-01 is the catalog part number and V x.xx is the ﬁrmware version number.
