The SL300 PC Programmer

This free tool is upgraded with each release of a SL series module. When used with the SL332/SL335 it can set functions that are not available using the top mounted switches. The SL300 Programmer can read and program all parameters for the entire range of Smart Line signal conditioners.


Main Screen Display

The top BAR displays input settings and input measurement of the connected module.

The right hand bar displays the output settings, output and various parameters of the connected module.

The client area allows data entry and retrieval of program data. Multiple programs can be viewed in the client area by selecting the appropriate tab located directly above the client area.

New tabs are opened by pressing SL Settings or Open File on the top bar.

Entry Parameters - vary with module number

Input Select Measurement type / Range or sensor
Range Minimum to maximum of measurement unit.
Measurement Unit Unit of measure that the range is calibrated.
Sensor Input device external to the isolator measuring the parameter.
Shape Linear = Direct relationship between measurement and reading. Table = A correction table is applied to correct errors in the input sensor.
Auxiliary A power supply available to the input terminals used to power the sensor.
Loading Resistance added across measurement terminals to reduce noise or bias inputs.
Response Time taken for input measurement to be reflected in the output. The Fast / Slow response function is input filtering to reduce jitter in the measurement.
Engineering Unit In many cases it is the same as the measurement unit however the measurement unit can be rescaled into a user unit that more closely represents the process being measured.
Engineering Min Minimum process value that corresponds to the minimum measured unit value.
Engineering Max Maximum process value that corresponds to the maximum measured unit value.
Input Type Standard = Input is measured between the input and return terminals. Differential = Input is the difference between two measured values.
Action Direct = The output rises from minimum to maximum as the input rises from minimum to maximum. Reverse = The output falls from maximum to minimum to as the input rises from minimum to maximum.
Signal Limits When available HIGH and LOW limits can be set over the entire output signal range.

Linearisation Tables (Shape)

Standard signal isolators produce a linear output in response to a linear input. This means that when plotting output against input on a line chart the result would be a straight line.

SL300 plots input on the vertical axis and output on the horizontal axis. Many measurement applications require the input output response to be tailored to correct errors in the linearity of the measured signal.

Edit Linearisation Table

The SL series uses look up tables to linearise errors in the industry standard probes and provides this facility on the generic measurement ranges for you to correct errors in unusual probes or errors in your process parameter. When creating a user specified range;

  1. The horizontal axis is broken up into 101 equally spaced points that represents the output in engineering units.
  2. The vertical axis represents the input in measurement unit.
  3. The output point values cannot be changed, the input measurement to produce the output value is the parameter that is changed.
  4. Each progressive input value MUST be greater than the last.

Editing of each input point is accomplished by clicking on the chart or selecting the points from the drop down lists. Two drop down lists enable the selection of two points at once which then can then be joined either as a straight line or using the simple bezier function to curve above or below average using the bezier gain slider.

SL300/USC700 Programmer Setup

SL300 Programmer is free software used to configure and customise APCS SL series signal conditioning modules.

  • System Requirements: Microsoft Windows XP and above
  • Interface Isolation module: Computer Adaptor COA703-02

All of the following are supplied from the one DOWNLOAD package SetupSL300_USC700-YYMMC.exe.

  • SL300 PC Programmer
  • USC700 Programmer
  • USB driver (32/64 bit detected)

New versions of the install may be run without un-installing the old version.

Warning Hazardous Voltages

We are 99.9% sure that if you connect an SL series module directly to a USB port on your PC or mobile phone no damage either device will occur. Communication will not occur without the COA703 connected.

The SL devices are isolators. The SL300 interface connector is in most cases at the negative input measurement potential. This means that connecting to the unit must be via the COA703. The COA703 provides 2KV isolation, enabling safe operation while the unit is connected to an operating system.

The SL series is used in industrial environments, its +/- input terminals or +/- output terminals may be at elevated voltages to enable your application to work. Servicing on site should only be conducted by qualified personnel that are familiar with the installation. Application Package and Driver
