Message closing character

CR

– For host messages; carriage return (ASCII 13)

CRLF

– For device messages; carriage return (ASCII 13) + line-feed (ASCII 10)

Command chain separator character

When a message string contains more than one command, a pipe ( '|' ) character

separates each command.

Spaces between parameters or command terms are ignored.

12.1.4

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

or Ethernet 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.

12.1.5

Command Forms

Some commands have short name syntax in addition to long name syntax to allow

faster typing. The response is always in long syntax.

12.1.6

Chaining Commands

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.
