10.1.4  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. 

10.1.5  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.  

10.1.6  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.
