 The GP1 Counter is designed to count and maintain switch closure
pulse outputs from dry contact devices such as relays and
magnetic reed switches. A battery backed 32-bit counter which
can be read but cannot be reset accumulates the pulse count. The GP1 Counter provides
the necessary switch excitation voltage so that no external power source is required.
CAT–5 cable, provides electrical connection to the 1-Wire network. The output of
this sensor is digital, all data conversions are done internally. Therefore, distance
to the sensor is unimportant for data integrity and it may be placed up to 2000+
feet from the host using CAT-5 twisted pair cable. In addition all I/O and data
communications with the sensor are CRC16 error checked for accuracy.
The GP1 Counter has a built-in multidrop controller (DS2406) and a Battery backed
counter (DS2423) which provides two unique 64 bit registration numbers (8-bit family
code + 48 bit serial number + 8 bit CRC) assuring error-free selection and absolute
identity; no two parts are alike. Unique addressing allows I/O function to be identified
absolutely, no more dip switch address confusion. All unique counter identification
and calibration data is stored in on-board ROM memory for easy installation and
setup.
Because the OneSix DDE Server directly supports all EDS 1-Wire products and handles
all the communications with the counter module, you do not have to be a programmer
to use this product. Any Windows application that can use DDE can obtain the data
from the GP1 Counter counter module. Examples of such applications include Microsoft
Office products like Word, Excel, and LookOut; as well as Invensys' Wonderware Intouch,
National Instruments' LabView, and Capital Equipment Corporation's TestPoint.
If you are a programmer, it also includes development applications like Microsoft's
Visual Basic and Borland Delphi.
GP1 Counter requires an RS232 to 1-Wire host adapter such as the EDS HA3, HA4,
or T8DH.
