9 Kramer Protocol 2000

The 900xl is compatible with Kramer’s Protocol 2000, version 0.50. This

RS-232/RS-485 communication protocol uses four bytes of information as

defined below. For RS-232, a null-modem connection between the machine

and controller is used. The default data rate is 9600 baud, with no parity, 8

data bits, and 1 stop bit.

Note: Compatibility with Kramer’s Protocol 2000 does not mean that a

machine uses all of the commands below. Each machine uses a sub-set of

Protocol 2000, according to its needs.
