As shO'lm in Table 2, Parallel Channel.,,;is I/O address x8 (usually
(8)
and Parallel Channel B is I/O address x9 (usually 09). These channels can
be used as is, without jumpering. You can interface to the 34-pin
connectors J4 and J5 at the top of the board using the Bitstreamer II
Parallel I/O cable supplied by Vector Graphic. This cable comes with no
connector at the far end, enabling customization. J4 is Parallel Channel A
and J5 is Parallel Channel
8.
J4 and J5 34-pin connectors are numbered beginning with the front
left-hand pin as number 1. The back left-hand pin is nU!11ber 2. 3 and 4 are
the next two pins to the right, and so on, with odd pin numbers in the front
and even pin nlli~bersin the back.
The connector cable is set up so that the
lines are numbered 1 to 34 from left to right. ~~e functional definition of
each line is as follows:

34-pin Connectors for Parallel Channels
Table 12
Input is not latched. Output is latched.
Remember: Parallel Channel A output is reserved for mas:<ing interrupts if
such interrupts ar,=used. Parallel Channel 3 inpul:is used to clear the 55
Hz real time clock interrupt latch. To switch this function to Parallel
Channel A, cut the trace leading to U4 pin 1, and jumper U4 pin I to U17 pin
3.
