WARNING! The Parallel/SPI Port on your PC must be set to one of the following:
output only bi-directional
Try the SPI connection at the default parallel port setting first. If necessary, the
Parallel/SPI port may be configured in the bios of your PC.
C C o n n e c t o r S P I D e s c r i p t i o n ( P i n s 7 - 1 2 )
P i n 7 - + 5 V D C ( O u t p u t )
This output is a voltage supply for the setup cable only. It is not designed to
power any external devices
P i n 8 - S P I C l o c k
The Clock is driven by the Master and regulates the flow of the data bits. The
Master may transmit data at a variety of baud rates. The Clock cycles once
for each bit that is transferred.
P i n 9 - L o g i c G r o u n d
This is the Ground for all Communication.
P i n 1 0 - M I S O ( M a s t e r I n / S l a v e O u t )
Carries output data from the MDrive17 and MDrive 23 back to the SPI
Master. Only one MDrive can transmit data during any particular transfer.
P i n 1 1 - C S ( S P I C h i p S e l e c t )
This signal is used to turn multiple MDrive17 or MDrive23 on or off.
P i n 1 2 - M O S I ( M a s t e r O u t / S l a v e I n )
Carries output data from the SPI Master to the MDrive17 or MDrive23.
