30 DSC2P Hardware Manual
ETEL Doc. - Hardware Manual # DSC2P / Ver H / 6/1/11
Remark: This diagram shows the use of DOUT1, but it is the same with DOUT2, DOUT3 and DOUT4.
Remark: The converter used for the analog input is a 12 bits converter.
The commutation times of the above-mentioned inputs and outputs are as follows:
Remark: The above-mentioned times takes only the hardware into account. To have the entire time, a delay
(max. 1 STI) must be added to these times, to take the treatment of the command by the software
into account.
