16Ch/12Bit Analog Multi-Function I/O Board for ISA

AD12-16(PC)EH is PC/AT and a highly efficient analog input board for the compatible machines. It has the analog input function to change an analog signal into a digital signal, the analog output function to change a digital signal into an analog signal, the digital input-and-output function of a TTL level, and also counter ability.

	Single end 16 channels and differential 8 channels (analog input function): Selection of a single input or a differential input is possible with the jumper on a board. The turn of the channel to change can be beforehand set as an exclusive register arbitrarily. Moreover, by using optional accessories, a maximum of 32 numbers of input channels can be extended, or a simultaneous sampling function, an isolated input function, etc. can be realized.
	Loading of a mass buffer memory (analog input function): The buffer memory for 256K data which can be used in FIFO or ring form is carried on a board. The sampling as background processing independent of the throughput of a personal computer is possible.
	A various sampling control function (analog input function): A start/stop of a sampling can detect and control the external signal of the size of not only the command of software but an analog signal, or a TTL level. Moreover, selection of the exclusive clock on a board or an external clock signal is possible for the sampling clock which determines sampling speed.
	Analog output function: Carry the analog output function of one channel. With this one board, construction of a data acquisition system is possible in accordance with an analog input function.
	Digital input-and-output function: It has four digital inputs of a TTL level, and four digital outputs. This one board can also perform the monitor of external apparatus, and control easily.
	Counter ability: It has the independent counter equivalent to i8254. Of course in accordance with a digital input-and-output function, the counter control from the outside is also possible for operation with a software command.
