Commands chain separator char:
When a message string contains more than one command, a pipe ( '|' ) character separates each command.
Spaces between parameters or command terms are ignored.
Entering 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.
Command forms:
Some commands have short name syntax beside the full name to allow faster typing, response is always in long syntax.
Command 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.
Commands in the string do not execute until the closing character is entered.
A separate response is sent for every command in the chain.
maximum string length:
64 characters.
