APD module C10508-01 Variable gain, stable detection even at high gain The C10508-01 consists of an APD, current-to-voltage converter, high-voltage power supply circuit as well as a microcontroller for compensating temperature with high stability on the basis of information received from the temperature sensor. The microcontroller contains coefficients according to the temperature characteristics of the APD. This allows highly stable APD gain over a wide temperature range even at high gain. The gain can be adjusted using a switch on the circuit board or commands from a PC. Features Applications Gain temperature stability: ±5 % or less (Gain=250, Ta=0 °C to +40 °C) APD evaluation Adjustable gain The gain can be adjusted with a switch or commands sent from a PC. Optical power meters Low-light-level detection Easy handling: Requires only a ±5 V power supply.

The gain can be set to an integer value between 5 and 400. Note that the setting is cleared when the power is turned off. Communication with PC · Communication Baud rate Data bits Parity Stop bits Flow control · Commands conditions : 9600 bps : 8-bit : None : 1-bit : None Command #UG Description Queries the current gain setting. The default gain is 10. Sets the gain to use when the switch is set to 9. The setting range is 5 to 400. A value outside the range will result in error. At power-on, the gain is set to the same setting as switch position 8. Sets the gain to use when the switch is set to 8. The setting range is 5 to 400. A value outside the range will result in error. The value will be retained even after the power is turned off. #US #UW · Send command format (ASCII code: 9 characters) 9 # 8 7 AA No. 9 8-7 6-3 2-1 6 5 4 xxxx 3 2 <CR> 1 <LF> Description # Command (2 bytes: US/UG/UW) Data (4 bytes: 0000 … 9999) Terminator (2 bytes: carriage return + line feed) 5 APD module · C10508-01 Receive data format (ASCII code: 9 characters) 9 * or $ 8 7 AA No. 9 8-7 6-3 2-1 6 5 4 xxxx 3 2 <CR> 1 <LF> Description * (normal) or $ (error) Command (2 bytes: echo back) Data (4 bytes: 0000 … 9999) Terminator (2 bytes: carriage return + line feed) Sample software A sample software program is contained in the supplied CD-ROM.
