Appendix A. Driver Notes
Appendix A.1. Continuous Map Descriptors
RS View has been known to crash if it tries to read a Server mapping that is discontinuous.
e.g. Server map 1: N21: 0-31
Server map 2: N21: 32-100
This will panic the FieldServer and crash RS view as the DF1 will attempt to map N21: 0-100
If set up as:
Server Map 1: N21: 0-100 No problems are experienced
Appendix A.2. Checksum
You can now specify a checksum parameter for the serial connection.
The heading keyword is "Checksum" and the possible values are
1) BCC or 2) CRC-16
If nothing is specified it defaults to BCC.
Example:
Connections
Port, Baud, Protocol, Checksum
P1, 9600, DF1_FD, CRC-16
The Checksum is valid for both DF1_FD and DF1_HD.
