SECTION 1: INTRODUCTION
1.1 PURPOSE OF THIS GUIDE
The purpose of this guide is to provide installation and commissioning procedures and basic
installation and operating instructions for the ONICON D-100-N2 Display Module 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 Metasys®N2 serial interface to
communicate data to the building control network.

1.4.1 RS485
N2 RS485, 2-wire (half-duplex) serial output connections are connected to
terminal as shown. Do not exceed 4.4 in-lb (0.5 Nm) of torque when tightening.
CAUTION
Only qualied service personnel should make connections between the D-100-N2 Display and
the user’s external equipment. ONICON assumes no responsibility for damage caused to the ex-
ternal equipment as a result of an improper installation.
!
CAUTION
Incoming and outgoing RS485 cable shield wires should be connected together, but must not be
connected to the D-100.

1.4.2 Optional Network Interface With Isolated Digital Pulse Input (Di3)
The D-100-N2 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 value 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 is required to congure the input 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 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 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.

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 20 mA at 20 VDC.

1.5 RS485 BIASING AND TERMINATION
1.5.1 Biasing and Termination
The ONICON D-100-N2 does not provide biasing voltage or termination to the RS485
network. A 120Wtermination resistor should be used when the meter is installed at the
end of the line.
1.6 NETWORK ADDRESSING
Before the D-100 can communicate on the N2 network, the appropriate device address must
be programmed into the display. The N2 network address for ONICON D-100 displays may be
set to any address from 001 to 255. This address is set at the display. Section 1.6.1 details the
procedure for changing this address.
1.6.1 Changing the Device Address
Every ONICON D-100 is individually programmed at the factory with application specic
data provided by the customer during the ordering process, and this may include
network addressing information. If the device address information was provided, the
display will be programmed with that number. If no address is provided, ONICON
displays are programmed with a default address of 017. The address may be changed at
the D-100 using the procedure outlined in the table below.
STEP ACTION REACTION COMMENT
0Obtain a device address from the
network administrator.
The device address is a
three digit number between
001 - 255, excluding zero.

IMPORTANT NOTE
Auxiliary pulse input (Di3) totalizes pulses. The engineering units and multipliers associated
with the total are not dened by the D-100; they are dened by the pulse output of the meter
connected to the auxiliary pulse input.
E.g. a domestic water meter with a pulse output is connected to the auxiliary pulse input. The
water meter output is scaled to 100 gallons per pulse. ADF5 could be congured as: CSAD

SECTION 3.0: NETWORK TROUBLESHOOTING TIPS
3.1 TROUBLESHOOTING
Reported Problem Possible Solutions
Device will not communicate
with the network controller.
• A unique address is required for each device on the
network. Duplicate addresses will cause some or all of the
devices on the network to quit working. (See section 1.6.1
of this manual for details.)
• The RS485 network cable connections are polarity
sensitive and must be connected the same way on every
device. (i.e. + to + and - to -). (See section 1.4.1 of this
manual for details.)
• Shield drain connections should be daisy chained in the
same manner as the signal cables for RS485. The shield
drain wire should be left unterminated at the end of the
cable and connected to earth only at the supervisory
controller. Shield wires must not be connected to the
RS485 connector on the D-100.
• The maximum number of devices allowed on a RS485
network segment without a repeater is 32. Adding more
than 32 devices to a single segment may reduce the
transceiver output voltage to a level that is too low to be
distinguished from background noise on the cable.
• RS485 cable impedance should be matched to a
termination resistor at the end of the cable. ONICON
boards do not have a resistor for termination. A resistor
should only be used if the display is the last device on
the network cable. (See section 1.5.1 of this manual for
details.)
Network communications are
disrupted when the device is
connected.
• The RS485 network cable connections are polarity
sensitive and must be connected the same way on every
device. (i.e. + to + and - to -). (See section 1.4.1 of this
manual for details.)
• A unique address is required for each device on the
network. Duplicate addresses will cause some or all of the
devices on the network to quit working. (See section 1.6.1
of this manual for details.)
• Shield drain connections should be daisy chained in the
same manner as the signal cables for RS485. The shield
drain wire should be left unterminated at the end of the
cable and connected to earth only at the network master
controller. Shield wires must not be connected to the
RS485 connector on the D-100.
