17.1Switching Protocols

You can switch protocols either via the front panel buttons (see Section 17.1.1) or the protocol commands (see Section 17.1.2).

17.1.1Switching Protocols via the Front Panel Buttons

To switch from protocol 3000 to protocol 2000 via the:

Front panel buttons, press the IN 1 and IN 2 button simultaneously

Infrared remote control transmitter, press the TAKE button and then 13

To switch from protocol 2000 to protocol 3000 via the:

Front panel buttons, press the IN 1 and IN 3 button simultaneously

Infrared remote control transmitter, press the TAKE button and then 16

17.1.2Switching Protocols via Protocol Commands

To switch from protocol 3000 to protocol 2000, send the following command:

#P2000<CR>

To switch from protocol 2000 to protocol 3000, send the following command:

0x38, 0x80, 0x83, 0x81

The Windows®-based Kramer control software1 operates with Protocol 2000.

If the VP-81KSiis set to Protocol 3000, it is automatically switched to

Protocol 2000.

17.2Kramer Protocol 3000

This RS-232/RS-485 communication protocol lets you control the machine from any standard terminal software (for example, Windows® HyperTerminal Application).
