CNT-3204MT-LPE
Connecting the control signal input/output
Connection of a control input
The control input signals consist of one pin per channel that can be selected as the channel's counter
start/stop or preset, and one pin per board that can be used as the start, stop, and clock for sampling. The
signals are LVTTL-level (3.3V) inputs.
As pull-up resistors (10K
Ω
) are provided on the board, connect the pull-up voltage to the pull-up pins if
connecting to an open collector output circuit/TTL level output circuit. (Please match the pull-up
voltage to the driving voltage on output side IC. If using 3.3V, connect to the VCC pin on the board.)
Not connecting the pull-up voltage may affect the control input pin left unconnected.
Remarks
The pull-up pins are PUP1 (pin 32 *1) for the counter input signal and PUP2 (pin 66 *1) for the
control input signal.
PUP1 (pin 32) : Pull-up for A, B, and Z phase input signal
(A0, B0, Z0, A1, B1, Z1, A2, B2, Z2, A3, B3, Z3).
PUP2 (pin 66) : Pull-up for the control input signals and for the sampling input signals
(DI0, DI1, DI2, DI3, CLKIN, STARTIN, STOPIN)
*1: Connector pin number on the board.
Control input circuit and its sample connection
*1 : The pull-up pins are PUP1 for the counter input signal and PUP2 for the control input signal.
