For control of multichannel detector head and data acquisition
C7557 is specifically designed for basic control in multichannel photometry. When connected to a Hamamatsu multichannel detector head and a
personal computer, C7557 allows easy control of the detector head and data acquisition by using dedicated software that comes with the unit.
C7557 supports all models of Hamamatsu multichannel detector heads designed to use a CCD image sensor or InGaAs image sensor. C7557
provides various useful functions (see page 2) that efficiently collect sample data during basic operation.
C7557 controller includes a driver/amplifier circuit for operating a multichannel detector head, a power supply circuit, a temperature stabilizer
circuit, an A/D conversion circuit that converts analog signals from the detector head into digital signals, and a data interface.
The software supplied with C7557 allows easy control of the multichannel detector head and data acquisition through the SCSI interface. This
software runs on Windows 95/98/Me, by simple operation from the menu neatly displayed on the screen. This software is available with different
kinds of DLL*
*1: DLL is one of useful functions the Windows 95/98/Me. It is a library that can freely start up from application software or execute function
procedure. Software development can be made easier with DLL. To use DLL, see the operation manual that comes with the unit.

■ Operation method
1. Make connections as indicated in ➀ to ➄.
➀ LINEConnect to the power cable.
➁ SCSI
➂ TE CONTROL I/OConnect to the "TE CONTROL I/O" terminal on the detector head.
➃ SIGNAL I/OConnect to the "I/O SIGNAL" terminal on the detector head.
➄ GNDWhen a 2-pin AC plug is used with the power cable, use this GND connector to ground the unit.
2. When all the connections are complete, turn on the power to C7557.
3. Install the dedicated softeware. (For details on the dedicated software, refer to the operation manual supplied in the package.)
*4: A terminator must be plugged into the last unit in the SCSI chain.

■ Software functions
The figure below shows the main screen (CCD image sensor: line binning) while running on Windows 95/98/Me.
From the main screen menu, you can easily set operating conditions for the multichannel detector head and data acquisition
parameters. The measurement screen displayed with this software shows the image sensor channel along the horizontal axis
and the output count along the vertical axis. The main screen menu also allows you to select the desired operation mode: line
binning or area scanning (for CCD image sensors), or line scanning (for InGaAs image sensors).
The parameters that can be set on the main screen are as follows:
•Exposure time
•Amplifier gain
•Cooling control
•Number of integrations
•Dark correction
•Type of measurement data
•Start or end of measurement
•Detector head status
•Trigger mode
•Trigger polarity
•Shutter timing pulse width
•Shutter timing pulse delay
•Shutter timing pulse polarity
