The D1000 and D2000 Series digital

transmitters are a complete family

of easy to use interface modules

for personal computers and other

processor based equipment with

standard serial I/O ports. The modules

convert analog input signals to

engineering units and transmit, in

ASCII format, to any host computer

with a standard RS-232C or RS-485

port. This modular design enables

anyone familiar with a personal

computer to construct a flexible and

cost effective data acquisition system.

These modules can measure

temperature, pressure, flow, voltages,

currents and various types of digital

signals. The D1000 series provide

direct interface to a wide variety

of sensors and perform all signal

conditioning, scaling, linearization

and conversion to engineering units.

Each module also provides digital

I/O lines for controlling devices

through solid state relays or TTL

signals. These digital I/O lines along

with integral limit setting capability

provide alarm and control outputs.

With the exception of the D1400

RTD and D1500 bridge modules,

every D1000 module contains an

on-board event counter. The event

counter will count up to ten million

transitions on the digital input line.

All user selectable options (address,

baud rate, alarms, etc.) are done

through the communications port

and stored in nonvolatile memory

thereby eliminating switches or

external adjustments of any kind.

The flexibility of this system allows

users to mix and match the modules

to fit their exact requirements.

As many as 124 modules can be

connected on one 4 wire cable.

They can be placed remote from the

host computer and from each other.

The D2000 series of user-

programmable data acquisition

and control modules allow direct

interface of non-linear analog

sensors to computers with serial

I/O ports.
