SECTION 1: INTRODUCTION
1.1 PURPOSE OF THIS GUIDE
The purpose of this guide is to provide installation and commissioning procedures and basic
operating and servicing instructions for the ONICON D-100 Dual Network Flow Display
Network Interface.
1.2 TYPICAL D-100 NETWORK INTERFACE MODULE
The D-100 is a totalizing display module that provides a local indication of liquid, gas or
steam ow rate and total data. It can also be congured with an optional network interface
to communicate data to the building control network. It is housed in a steel wall mounted
enclosure with a built-in user interface/display.

1.4 PROTOCOL SELECTION
The D-100 Dual Network Flow Display is provided with an IP connection and a single RS485
connection. Both MODBUS TCP/IP and BACnet UDP/IP are always available from the IP
connection via a single IPv4 IP address. The RS485 connection can be congured for BACnet
MS/TP or MODBUS RTU. The protocol options are selected via dip switch settings. The table
below identies the dip switch settings for each protocol. The switch settings also control
which network is allowed to remotely reset totals on the network.

1.5 NETWORK SIGNAL CONNECTIONS
1.5.1 RS485
Use 18 – 22 twisted shielded cable for RS485, 2-wire (half-duplex) serial
communications. The cable is connected to terminal T1A. Do not exceed 4.4 in-lb (0.5
Nm) of torque when tightening the terminals.
CAUTION
Only qualied service personnel should make connections between the D-100 Flow Display
and the user’s external equipment. ONICON assumes no responsibility for damage caused to the
external equipment as a result of an improper installation.
!
Terminal
T1A
G terminal only used
for 3-wire installations.
Do not connect shields
to this terminal.
CAUTION
Incoming and outgoing RS485 cable shield wires should be connected together, but must not be
connected to the Btu meter.

1.5.2 BACnet/IP and/or MODBUS TCP/IP
BACnet and/or MODBUS, 10Base T output connections are made through a single Rj45
connector as shown.
!
CAUTION
Only qualied service personnel should make connections between the D-100 Flow Display and
the user’s external equipment. ONICON assumes no responsibility for damage caused to the
external equipment as a result of an improper installation.

1.5.3 Optional Network Interface With Isolated Digital Pulse Input (Di3)
The D-100 Flow Display can be provided with an auxiliary pulse input for totalizing
pulse outputs from external devices such as water or gas meters. Pulses are accumulated
in an internal register. The totalized value is shown on the display and is available on
the network. This register can be zeroed via the network. The maximum register total is
9,999,999. The register will rollover to zero when this value is exceeded.
If the auxiliary pulse input option was ordered at the same time the Display was ordered,
it will arrive fully congured and ready to use. If it was ordered after the Display was
delivered and is being installed as a eld upgrade, it may be necessary to congure the
pulse input. The information required to congure the input is provided below and on the
following pages:
The input pulse must meet the following criteria:
1. Frequency input range, 50 Hz maximum
2. 10 millisecond minimum pulse duration
Input Pulse Denition:
In order to congure the communications card auxiliary pulse input, you must rst
determine which type of pulse your meter produces. The allowable types of input pulses
are described on the following pages. Based on the type of pulse, set the selector switch
(S1) on the communications circuit board (Fig. 1) to the correct setting.

Powered Pulse:
This type of output refers to a pulse which has an associated voltage with it (see Fig. 2).
Set the selector switch, S1 to Pwrd Pulse. The allowable voltage range is 5-24 VDC. The
input impedance is set at the factory to be 11 KOHM via the impedance selector jumper
(J1, see Fig. 1). A lower impedance, 3 KOHM can be selected if required by the instrument
providing the pulse output. Consult the instrument manufacturer or ONICON if you are
uncertain as to the proper jumper selection.
Fig. 2
Open Collector (Sourcing):
This type of output refers to an open Collector Switch congured for a sourcing function
(see Fig. 3). Set the selector switch, S1 to SRC. The switch must be rated for at least 20 mA
at 20 VDC.
