CONNECTOR DESCRIPTIONS

The CLCI2000 Series Indexer will come with either one or two 37 Pin D-Sub Connectors. For a CLCI2001 and CLCI2002, there is only one connector. For a CLCI2003 and CLCI2004 there is a second connector that connects to the board via a 37 pin ribbon cable. This second connector will need a port location to screw down to. NOTE: This does not require an extra expansion slot to plug into, but only a space to screw down the connector. The connectors are Female D-Sub types. The pinouts for the first connector (axis A and B) is slightly different than the pinouts for the second connector (Axis C and D).

DB37 PINOUT FOR AXES A & B

+5VDC

This is the +5VDC supplied by the computers power supply. See your Computer Manual for the specifications regarding this pin.

CLOCK SIGNALS

This is the signal that will be connected to the Step Motor Driver. The driver will take one step for every clock pulse sent to it. For instance, if a pulse train of 1000 pulses is sent at 50 Hz (50 clock pulses per second) to the driver the step motor will go 1000 steps, and will take 20 seconds. The output clock is TTL/CMOS compatible. The source current rating (Voh = 2.7 V) is 12mA. The sink current rating (Vol = 0.5 V) is 9mA. The clock signals are negative going.
