7.3.3 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.
