1.1 Recorder Description
The Solid State Data Recorder is a Paperless Recording instrument. Data is stored on either an internal floppy
disk, a removable PCMCIA memory card or a Zip Drive.
All data is stored in MSDOS format and may be archived or analyzed on any IBM compatible PC running Microsoft
Windows 3.1 or Windows 95/98 using the available Companion Software. The instrument retains all the features of
a traditional Paper Chart Recorder by virtue of its large STN monochrome or TFT color Liquid Crystal Display (LCD)
which presents the data in the traditional chart mode as well as in bar graph or digital numeric form.
The unit has many features and functions which are unique and cannot be performed on traditional paper recorders,
such as data compression and historic data browsing. The recorder is programmed via a touch screen keypad on
the display .
The recorder will measure and process up to six direct inputs, calculated, conditional, or external points for logging,

1.2 Recording Options
The Recorder can be ordered with one of three storage mediums: a standard PC compatible floppy disk drive,
an industry-standard PCMCIA memory card drive, or a Zip drive. The optional Companion Software supports al l
three media types.
1.2.1 Floppy Disk Drive
The Floppy disk drive uses PC compatible 3½ inch (89mm) floppy disks. These disks store 1.44 Megabytes
of data which translates to approximately 700,000 data samples (each sample is 16 bits). The disks are
magnetic media and the drives are mechanical. This limits their use in harsh environments where vibration or
temperature is a problem, but they are convenient as they are very inexpensive and can simply be plugged into
any IBM compatible PC.
1.2.2 PCMCIA Memory Card
The PCMCIA card (Personal Computer Memory Card Interface Association) is a small solid state card
containing Flash memory . The PCMCIA drive supports memory cards up to 200 Megabytes in size which is
approximately 100,000,000 data samples. The cards do require a special drive in your PC which is readily
available, inexpensive and already standard on many laptops and desktop machines. Contact your dealer
for details.
NOTE: It is recommended that a Sandisk 4-200 Meg Flash card be used.
1.2.3 Zip Drive
The Zip Drive stores 100 Megabytes of information which is approximately 50,000,000 samples for a 100
Megabyte Disk. This Recorder does not support 250 Megabyte Zip drives.
1.3 Recorder Options
Additional functions and capabilities can be added to the Recorder and are described in the following paragraphs.
1.3.1 Digital Input and Output

2.3.1 Power Requirements
The Recorder operates on any voltage from 100 to 240 Vac +10%, 50/60 Hz enabling it to be used in most
countries. The maximum apparent power required by the unit is 35 VA.
2.3.2 Power Connections
NOTE: The recorder is designed to be panel mounted and as such should be considered as
permanently connected. Disconnection from the supply must be possible via a customer supplied switch
or circuit breaker. This disconnection device must be included in the panel installation and should be
clearly marked, in close proximity to the Recorder and easily accessible to the operator.
All connections to the Recorder are made to the Rear Terminal Panel. Any wiring carrying hazardous voltages
must conform to all applicable local and national safety codes. AC Mains connection is via an internationally
accepted IEC 320 AC mains connector or screw terminal (Figure 2-4 and Figure 2-5).
WARNING
Ensure all mains power is turned off before proceeding with installation. This unit
is provided with a mating connector for the ac power socket or with a compatible
three wire grounded cable which may be terminated with a plug. Always ensure
the ground wire (green or green and yellow) or ground pin of the plug, is connected
to a low impedance safety ground (earth) within the ac power distribution system
you are using. Always use the recommended mating connector and an approved
three wire cable to connect this unit to the ac mains. Always provide a low
impedance safety ground wire to the ground lug on the rear panel marked .

generator stator winding).
Figure 2-6 DC2000 Rear Panel Connections
Page 2-6
Chapter 2 Installation and Wiring
The Recorder accepts up to six direct inputs. Input connection is via plug in screw terminal connectors on the
rear panel. Inputs can be mixed in any combination of thermocouple, RTD, milliamps, millivolts, volts or contact
inputs. There is a common ground lug marked with a
Read the following procedures prior to connecting inputs to the terminals.
WARNING: Ensure the power is off before connecting signal inputs to the unit.
The plug in screw terminal connectors are of the clamping screw variety, putting even pressure on the signal
wire. It is therefore not necessary to terminate the wires with lugs, however you may do so if you wish. The
maximum gauge wire that can be accommodated is 14 AWG or 2.5 mm². You will need a small screwdriver and
a pair of wire cutters and strippers. The use of shielded twisted lead wire is recommended to minimize electromagnetically induced noise.
WARNING: All unused inputs must have all contacts commoned togther.
CAUTION: Never run signal and power or control wiring together in the same conduit. This is to
prevent possible recording error due to induced signals between lines. Route signal
wires away from power wires at the rear panel.
NOTE: Ground cable shields at one end only to eliminate the possibility of interference due to
ground loop currents. When grounded transducers are used, the shield should be grounded
at the sensor end only.

2.3.4 Relay Output, Contact Input
WARNING
To prevent the possibiltiy of electrical shock, use extreme caution when wiring
contact output connections. Hazardous potentials may exist on contact output
terminals which are floating with respect to instrument ground. These hazardous
potentials may be exposed on the rear terminal panel of your instrument. Any
voltage potentials at the contact circuit will exist on the instrument’s respective
contact output terminals (i.e. line-powered circuits).
2.3.4.1 Mechanical Relay Option
The Recorder may be equipped with an optional Digital Input Output Board which has three or six potential
free Form C relay contacts and three opto-isolated digital inputs. A terminal block as shown in Figure 2-8
below, is provided for the three alarm output Potential Free Form C connections: Normally Open (NO),
Common (C), and Normally Closed (NC), and the three digital inputs which share a common. The relay
contacts are capable of switching 125 Vac ~ at 0.5 Amp or 30 Vdc at 2 Amps. The potential free relay
contacts are protected internally with 300 volt Metal Oxide Varistors (MOVs) to prevent contact arcing.
Figure 2-8 Mechanical Relay Connections (3 Channel Shown)
2.3.4.2 Solid State Relay Option
The Recorder may be equipped with an optional Digital Input Output Board which has three or six solid
state open collector outputs and three opto-isolated digital inputs. A terminal block as shown in Figure
2-9 below, is provided for the alarm output connections. The output connections are polarized and are
intended for DC operation only. Reverse polarity protection is provided and each output is fused at 1 Amp.
The fuse is solid state and will reverse once the load is removed. The outputs are rated at 30 VDC at 0.5
Amp and are optically isolated from the recorder.
Figure 2-9 Solid State Relay Connections (3 Channel Shown)
2.3.4.3 Opto-isolated Inputs/Outputs
The opto-isolated inputs require an external potential of 5 to 12 volts DC @ 10 milliAmps. The three inputs
are isolated from the unit, but not from each other as they share a common. The positive voltage connects
to the terminals marked 1, 2 or 3 and the common connects to the terminal marked C. It is possible to use
potential free contacts to operate the digital inputs. This requires opening the unit and setting jumpers on
the relay board. Refer to Appendix A for details.

2.4 Serial Interface Option
Data can be accessed to download Configuration files or Data files using the RS232C option and a modem. The
RS485 option allows the Recorder to be installed into an existing Modbus network or it can be used to connect up
to thirty-one recorders in series. A standard DB9 Female connector is required for the RS232 to connect to an IBM
PC compatible computer using a null modem cable and the RS232 can support cable runs up to 50 feet [16 m]. The
RS485 connection is via two wire (twisted pair) cable (a DB9 Female connector is required) and can support cable
runs up to 4000 feet [1300 m].
The Serial Interface contains an isolated switching unit for RS232 and RS485 access with a standard DB9 Female
connector. When switch 2 is in the ON position, RS485 is enabled. When switch 2 is in the OFF position, RS232
is enabled.
When more than one recorder are connected in a series, it is necessary to apply a termination resistor on the last
recorder. Switch 1 in the ON position applies this necessary termination resistor and should be switched to the ON
position only on the last recorder in series.

The RJ45 Connection for the Ethernet are as follows:
Receive Differential Pair
3 RX6 RX+
Transmit Differential Pair
7 TX8 TX+
Two LEDs on the rear panel show Ethernet activity. The Link LED indicates a good connection and the RxTx LED
indicates communication activity.
2.6 Cleaning
The unit may be cleaned by wiping with a soft cloth. The front panel and display / keypad may be wiped with a
slightly damp soft cloth containing soapy solution or a mild detergent. Do not use any lemon based (citric acid)
product to clean the display / keypad.
2.7 Contrast Adjust (Monochrome Only)
The contrast or viewing angle of the monochrome LCD display can be adjusted from the side panel. If not
adjusted correctly, the display may look dim, dirty, completely black, washed out or blank. Insert a small star or
Phillip type screwdriver into the hole in the side panel as shown in Figure 2-12 and turn to adjust the display
contrast. The adjustment potentiometer has a 270° rotation. Do not apply excess pressure or attempt to
turn it beyond the end stops.
