The selectable communication baud rates are 9600, 12000, and 38400. The communication protocol is one start bit, one stop bit, 8 data
bits, and even parity.
When RS-485 communication is used, each controller module may be assigned a controller ID. Select letter A through O for individual
identification of up to 15 Controllers on a RS-485 "party line."
Configuring the Serial Transmission Format
Serial Transmission activates the serial port, specifies the data format, and provides data suppression options.
If No Serial Communication is selected (default), the serial port does not transmit sensing data.
ASCII Transmission specifies the scan data uses the ASCII format. ASCII Transmission has one suppression option, Suppress Clear Data,
which sends data once when the array is completely clear (i.e., when no beams are blocked) and no further data is sent until one or
more beams are blocked.
Binary Transmission specifies the scan data uses the binary format. The binary format has three suppression options:
•
Suppress Clear Data: Sends data once when the array is completely clear (i.e., when no beams are blocked) and no further data
is sent until one or more beams are blocked.
•
Suppress Header: Reduces the size of the controller serial message by three bytes. Header bytes consist of the two byte start
string plus the termination byte.
•
Compress Data: Reduces the number of data bytes sent for each analysis mode from two to one byte.
5.4.7 PSF Assignment and Storage
The screens shown are for MAC-1, MACP-1, MACN-1, MACV-1, and MACI-1 Controllers. The screen layouts for MAC16N-1 and
MAC16P-1 are functionally the same. PSF commands are located in the lower right corner of the PSF Configuration screen.
Sending a PSF to the Controller
After a PSF is configured, select Send PSF to send the PSF to the MINI-ARRAY controller. This command loads the PSF into the
controller's non-volatile memory and automatically overwrites any existing PSF. The program confirms that the PSF was accepted or it
will prompt for changes that are still required.
Retrieving a PSF from the Controller
To check the PSF loaded into the controller, select Upload PSF. The current PSF will be displayed on the PSF Configuration screen.
Downloading a PSF to Your Hard Drive
To download the PSF from the controller and save it to your hard drive, follow these steps.
1. Select File Save PSF.
2. When prompted to save the PSF to a file, select Yes.
The FileSave pop-up window appears.
3. Overtype *.psf in the File Name entry box by entering the name of the file to be stored (up to 8 characters), plus the .psf
extension.
For example, type the name Inspect1.psf.
4. Select OK or press the Enter key.
The PSF is stored on the selected drive (default is C:), and the program automatically returns to the PSF Configuration screen.
Uploading a PSF to the Controller
To upload a PSF from your hard drive to the controller, follow these steps.
1. Select File Retrieve PSF.
The FileBox pop-up dialogue box appears.
2. Select the desired PSF from the File Name list.
3. and select OK or press the Enter key.
The selected PSF loads on the PSF Configuration screen.
4. Click Send PSF to upload the file to the controller.
Analyzing the PSF Output Data
Follow these steps to view and analyze the output data generated by the PSF loaded into the controller.
1. Click Execute.
The Measurement Output pop-up window appears.
2. Click Run.
The table displays the status for the selected measurement mode(s), including the Present value, and the High and Low values
for the Run period.
