Use your PC initially to configure the settings (see section 7.5).
Communication Parameters 9 Communication Parameters Table 3: Communication Parameters RS-232 Protocol 2000 Baud Rate: 9600 Data Bits: 8 Stop Bits: 1 Parity: None Command Format: HEX Example (Output 1 to Input 1): 0x01, 0x81, 0x81, 0x81 Ethernet Default Settings Reset Ethernet Default Settings IP Address: 192.168.1.39 Power cycle the unit while holding in the Factory Reset button, located on the rear panel of the unit.
Kramer Protocol 2000 11 Kramer Protocol 2000 The VS-44H is compatible with Kramer’s Protocol 2000 1 (version 0.50) (below) 2. This RS-232/RS-485 communication protocol uses four bytes of information as defined below. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.
Kramer Protocol 2000 For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1. Table 6: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
Kramer Protocol 2000 NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not defined / no valid input is detected; or 1 if it is defined / valid input is detected. NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2, 5 or 7, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT.
