CHAPTER 2 VIRTUAL TUNNEL
The CIU 888 allows service tools (TCP/IP clients), i.e. Engauge, to
communicate with gauges via the CIU 888 using the GPU protocol on
TCP/IP or FlexConn protocol on TCP/IP. The CIU 888 acts as a virtual
tunnel for transmitting the GPU/FlexConn messages between the
service tool connected to the Service port of the CIU 888 and the
gauges connected to the CIU 888.
NOTE: 1. FlexConn is a Honeywellproprietary protocol and will not be described
further in this manual.
NOTE: 2. Servicing of Honeywell BPM gauges and Honeywell TRL/2 gauges follows
the below path:
