Remote Operation
Configuring the IEEE-488 Port
1. Press the MENU key.
2. Select the SYSTEM MENU (F5) function key
3. Select the REMOTE INTERFACE (F2) function key
4. Select the USB (F2) function key
5. Use the Left/Right arrow keys to change PORT ENABLE to ON (enable).
Before plugging the USB communication cable from the Super-Thermometer into a computer, make sure
the computer is connected to the internet to allow the USB driver to download and install in the computer
automatically.
If an internet connection is not available, the computer will detect the Super-Thermometer as an unknown
USB device and will prompt for a driver. Insert the DVD provided with the Super-Thermometer into the
computer and browse into the USB driver folder. When the driver is selected, the PC will automatically load it.
The user may be prompted a second time to browse to the USB driver folder and repeat the process.
When the Super-Thermometer is recognized by the computer, it is ready for communication. Search in the
computer’s operating system to find the com port address assigned to the USB port connected to the Super-
Thermometer. Once the com port address is identified, remote operation commands can be sent using the com
port.
8.5 Configuring the RS-232 Serial Port
The RS-232 serial port implements the RS-232 communication standard. This port is always enabled. The RS-
232 parameters are 8 data bits, one stop bit, and no parity. The baud rate is user-selected. The physical port is a
9-pin D connector.
To configure the port, use the following to open the RS-232 configuration screen:
1. Press the MENU key.
2. Select the SYSTEM MENU (F5) function key
3. Select the REMOTE INTERFACE (F2) function key
4. Select the SERIAL (F1) function key
The RS-233 configuration settings are BAUD RATE and LINEFEED. Configure these settings as needed.
8.6 Configuring the IEEE-488 Port
The IEEE-488 port implements a common standard parallel instrument interface bus. The port is disabled by
default and must be enabled to be used. The user may specify the bus address. It provides the following IEEE-
488 defined capabilities: SH1, AH1, T6, TE0, L4, LE0, SR1, RL0, PP0, DC1, DT0, C0, E2.
The IEEE-488 configuration settings are PORT ENABLE, ADDRESS, and TERMINATION. To make
changes to these settings, use the following steps to go to the IEEE-488 configuration screen:
1. Press the MENU key.
2. Select the SYSTEM MENU (F5) function key
3. Select the REMOTE INTERFACE (F2) function key
4. Select the IEEE-488 (F4) function key
To use the port, ensure PORT ENABLE is set to ON (Enable) and set ADDRESS to an address that is not be-
ing used by another device on the IEEE-488 bus. The address may be set to a number between 1 and 30. The
default address is 22. Always press the ENTER key after changing the address.
TERMINATION determines if a carriage return character (ASCII code 13) or linefeed character (ASCII code
10) terminates a response. The default option is LINEFEED. An IEEE-488 EOI message also accompanies the
final character of every transmission.
The IEEE-488 port accepts either or any combination of, a linefeed, carriage return, or EOI as a terminator.
The CLEAR INTERFACE (F1) function key is used to clear the input and output buffers and reset the IEEE-
488 interface, just as if the IFC or SDC control message was received.
