•
Programmable dynamic filtering. The filtering is the same as used on Version 2 but with the advantage of
being able to set the characteristics using the communications.
•
Wide Operating Voltage. The operating voltage is now 5.6 to 18V allowing the device to be powered from a
wider range of available system supplies.
•
DC Excitation. DC excitation has now been employed allowing longer cable lengths for the load cells which is
particularly useful for DSC. This is a 4 wire measurement.
•
Defaults have been changed so that the device is shipped with a baud rate of 115200 and station number of
1.
•
Scaling implementation has been changed for both "CELL" and "SYS". The gain is applied before the offset
thus following the more standard approach. This allows for an offset change to be made easily as the offset
is not a component of gain.
Version 4 Additions and Enhancements
DSC
•
Reset to default communication parameters. A pair of pads on the underside of the DSC, when shorted
together at power up will reset Station no. to 1 and baudrate to 115200
Note: This is only for issue 3 pcb and higher. Please refer to underside for issue marking.
DCell & DSC
•
For ASCII versions. Setting Station No. to 998 gives continuous output streaming as version 3, except that,
on powering on streaming starts without requiring an XON character
The Product Range
Devices are available in two physical formats.
Which Device To Use
It is important to select the correct product for your application.
• First choose DCell or DSC based on your physical installation needs
• Choose the communications protocol depending on performance/integration requirements
• the RS232 output option may be simpler if your system only uses a single DSC card
Common Features
Both physical formats offer identical control and near-identical measurement performance
Both are available in all three output protocols: MODBUS, ASCII or MANTRABUS
Micron Meters DCell & DSC User Manual
The DCell (puck) products consist of a Digital Strain
Gauge Signal Conditioner with RS485 bus output in
double sided component population format.
This is suitable for installation in very small spaces,
including load cell pockets.
External connections are made by wiring to through
hole pads. Mounting is via a 2mm mounting hole to
accept M2 screw or American equivalent #0-80.
Important Note: DO NOT USE #2 screw size.
The DSC (card) products are very similar to the DCell
but in a different physical form for mounting stand-
alone or on a board.
The DSC is also available with an RS232 output.
External connections are via header pins which can
plug into connectors, or be soldered to wires or into a
host PCB. DSC has an open collector output and volt
free digital input.
