The Windows®-based Kramer control software
16.2 Kramer Protocol 3000
operates with Protocol 2000. If the
VP-8x8TP
is set to Protocol 3000, it is automatically switched to Protocol 2000.
This RS-232/RS-485 communication protocol lets you control the machine from
any standard terminal software (for example, Windows
®
HyperTerminal) with
default settings of 115200 baud data rate, no parity, 8 data bits, and 1 stop bit.
