APPENDIX B
PLANNING AND CONNECTION OF PI’S
GENERAL
This appendix provides the general rules with planning and connecting PI’s and tag readers/printers
to the LAN 8 port CommVerter.
Regarding PI type RS-485 interfaces, only the same brand pumps can be connected to either
channel. In case that any channel is left unused, Tag reader/printer can be connected to that port.
The Number of CPU heads connected to each PI has been optimized (see table in
paragraph 2.3).
All PI’s have protection against lightening/ESD
CONNECTORS
All the PI’s will be provided with relevant 8 pin connectors, each 4 pin shall represent a distinctive
channel.
