6.4 The OneWireless Communication Option (HCI-1WL)
6.4.1 Introduction
The Host Communication Instrument OneWireless (HCI-1WL) board is
a communication module for the instrument (gauge).

FIGURE 6-4 The HCI-1WL duplex board with flatcable interconnection
This module consists of 2 boards (see FIGURE 6-4): a standard
FlexConn board with a memory-card interface, and an interface board
with a standard Honeywell OneWireless Radio board attached. If this
wireless communication option is installed, the Instrument (gauge) can
communicate with a host system using the OneWireless network via 3
different ways :
 Directly via the OneWireless Network (using the HCI-1WL board).
 By using a protocol tunnel through the OneWireless network:
• Via the Enraf FlexConn Protocol.
• Via the Enraf GPU protocol.
OneWireless is an all digital, two-way communication mesh network
that interconnects industrial field sensors to a central system.
OneWireless has defined standards to which field devices and operator
stations communicate with one another. The communications protocol
