BM-7A Colorimeter Connection

The BM-7A colorimeter connection requires the use of a specific serial cable and certain configuration switches to be set in a particular manner. To establish the connection, a straight-through 9-pin female-to-female serial cable is needed. It is important to note that the cable used for the BM-7A colorimeter connection is different from the one used for the SR-3AR spectroradiometer. The configuration switches on the BM-7A colorimeter should be set as follows: Switches 1, 2, and 5 are down, while switches 3, 4, 6, 7, and 8 are up. The connection is made by connecting the BM-7A colorimeter to a serial port on the Calman computer or to a Serial to USB adapter using the straight-through serial cable. On the Calman Meter Settings tab, the user should click on Find Meter and select the appropriate Com Port.

SR-3AR Spectroradiometer Connection

To establish a connection with the SR-3AR spectroradiometer, a null modem 9-pin female-to-female serial cable is required, which is different from the cable used for the BM-7A colorimeter connection. The SR-3AR spectroradiometer should be set to a baud rate of 38,400, with a length of 7, parity set to even, stop bits set to 1, and delimiter set to CR+LF. It should be connected to a serial port on the Calman computer or to a Serial to USB adapter using the null modem serial cable. On the Calman Meter Settings tab, the Find Meter button should be clicked, and in the Find Meters popup dialog, the Com Port should be set to auto or the assigned com port for the meter or Serial to USB adapter. This setup ensures a proper connection between the SR-3AR spectroradiometer and Calman for accurate and stable measurements.

BM-7A Colorimeter Connection Procedure

The connection procedure for the BM-7A colorimeter involves setting the configuration switches on the device, adjusting the baud rate, length, parity, stop bits, and delimiter settings, and connecting it to a serial port on the Calman computer or a Serial to USB adapter using a specific type of serial cable. To ensure a successful connection, follow these steps:

  1. Set the configuration switches on the BM-7A colorimeter as follows: Switches 1, 2, and 5 are down. Switches 3, 4, 6, 7, and 8 are up.
  2. Configure the baud rate, length, parity, stop bits, and delimiter settings on the colorimeter. Set the values as follows: Baud rate = 38,400; Length = 7; Parity = Even; Stop Bits = 1; Delimiter = CR+LF.
  3. Connect the BM-7A colorimeter to a serial port on the Calman computer or to a Serial to USB adapter using a straight-through serial cable.

By following these steps, you will be able to establish a reliable connection between the BM-7A colorimeter and the Calman software, allowing for accurate and precise measurements in your color calibration process.

SR-3AR Spectroradiometer Connection Procedure

For successful integration of the SR-3AR spectroradiometer into your calibration process, a specific connection procedure needs to be followed. To begin, set the SR-3AR spectroradiometer menu options as follows: Baud rate = 38,400; Length = 7; Parity = Even; Stop Bits = 1; CS-900 On/Off = Normal Type; Delimiter = CR+LF. Next, connect the SR-3AR spectroradiometer to a serial port on the Calman computer or to a Serial to USB adapter using a null modem serial cable. Then, on the Calman Meter Settings tab, click Find Meter. In the Find Meters popup dialog, leave the Com Port set to auto or select the assigned com port for the meter or Serial to USB adapter. Following these steps will ensure a successful connection of the SR-3AR spectroradiometer for your calibration needs.

Meter Mode for BM-7A Colorimeter

The Meter Mode for the BM-7A Colorimeter is an essential setting that determines the correction factor used for measuring the display.
