    Reference Manual Appendix D: Redundancy 00809-0200-4420, Rev HC July 2015 D.4.3 Simplex RS-485 A simplex RS-485 host connection supports Modbus RTU protocol. When using this architecture, connect the secondary Ethernet port on Gateway A directly to the secondary Ethernet port on Gateway B. Then wire the RS-485 ports for both Gateways in parallel to a single serial card at the host system.

    Reference Manual Appendix D: Redundancy 00809-0200-4420, Rev HC July 2015 Gateway replacement When replacing or reintroducing a Gateway in a redundant system, always connect both the primary and secondary Ethernet connections before powering the standby Gateway. If the Gateway is being reintroduced (i.e. it was a part of the original redundant system), it will automatically rejoin the redundant system.
