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 MODBUS RTU serial 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 provided with an optional MODBUS RTU RS485 or
MODBUS RTU TCP/IP serial interface to communicate data to the building control network.

CAUTION
Only qualied 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.

1.4.3 Optional Network Interface With Isolated Digital Pulse Input (Di3)
The D-100-MODBUS Display can be provided with an auxiliary input pulse for totalizing
pulse outputs from external devices such as water or gas meters. Pulses are accumulated
in an internal register, and the totalized value is available on the network. This register
can be zeroed via the network. The maximum register total is 9,999,999. This 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 congured 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 congure the
pulse input. The information required to congure 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 Denition:
In order to congure the communications card for an auxiliary input pulse, 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 congured for a sourcing function
(see Fig. 3). Set the selector switch, S1 to SRC. The switch must be rated for at least 20mA
at 20VDC.

Open Collector Sinking or Dry Contact:
This type of output refers to an open collector switch congured in a current sinking
arrangement or a dry contact switch (see Fig. 4 and 5). Set the selector switch, S1 to Sink.
In either case, the switch must be rated for at least 20mA at 20 VDC.
