2.4.3.6 Extended Gateway configuration data
ext. Configuration byte Bit Function
Bit7 ..Bit2 Reserved
Bit1 Double baud rate
Bit0 RS232(0)<->RS422(1)
Table 7: ext. configuration byte Octet 17
BIT0: RS232<->RS422 – Serial interface physics
With this parameter the interface physics can be set to RS232(0) or RS485(1).
This parameter is only applicable for XPS-E. The desktop model (XPS) does
only have an RS232 physics.
BIT1: double Baudrate
Setting this bit doubles the baudrate for the serial interface
Exp: A selected baudrate of 19200 Baud can be increased to 38400 Baud by
setting this bit.
BIT7 – Bit2: reserved
