Spaces between parameters or command terms are ignored.

10.11Entering Commands

You can directly enter all commands using a terminal with ASCII communications software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial, Ethernet, or USB port on the Kramer device. To enter CR , press the Enter key.

( LF is also sent but is ignored by command parser).

For commands sent from some non-Kramer controllers like Crestron, some characters require special coding (such as, /X##). Refer to the controller manual.

10.12Command Forms

Some commands have short name syntax in addition to long name syntax to allow faster typing. The response is always in long syntax.

10.13Command Chaining

Multiple commands can be chained in the same string. Each command is delimited by a pipe character ( '' ). When chaining commands, enter the message starting character and the message closing character only once, at the beginning of the string and at the end.
