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

SAINT Keyword 2000 to RS-232 Gateway 01/20/04 Page 6 of 20 4 Message Format To minimize latency with the RS-232 link, all data is sent in binary form. The same data format is used to send and receive messages. The gateway supports bi-directional asynchronous communications. 4.1 Data Stream The host data stream is broken into messages. A message consists of a Message ID and one or more data bytes. The character FFh is used as an ESCAPE character to indicate the

Most likely causes of reset are power on reset, host commanded reset, or gateway micro watchdog error. The gateway does a cold start on all resets (all information is lost). The gateway will also report error conditions with the Report Error message below. See section 4.3.2.1 for error code definitions. The gateway will also ech
