SAINT Keyword 2000 to RS-232 Gateway 01/20/04 Page 5 of 20 3 RS-232 Setup The gateway uses the following RS-232 parameters: - 8 Data Bits - 1 Stop Bit - No Parity The gateway supported baud rate: 57600. Baud Rate 57600 The supported baud rate is sufficient for communicating with the Class2, Keyword, ACP, BEAN, and slower CAN bus’s. However, USB connection is recommended for high speed CAN communications. 3.1 Buffering and Flow Control Whenever th
