4.4 Commands
The device supports the IEEE488.2 Message Exchange Control (MEC) protocol. It
does not send data until it is asked for (this does not apply to the emulation codes).
White-space characters (ASCII codes 0 – 9, 0B
hex
– 20
hex
) are ignored on reception.
To terminate a program message (Controller ► Device) the ‘<LF>’ character (Line
Feed, 0A
hex
) is used. It is possible to put more than one command into a program
message using the ‘;’ character (semicolon, 3B
hex
) as a separator. The character
sequence ‘<CR><LF>’ (Carriage Return, 0D
hex
Line Feed, 0A
hex
) is used as the
response message (Device ► Controller) terminator.
