A.4 Use of Rabbit 2000 Parallel Ports
Figure A-6 shows the use of the Rabbit 2000 parallel ports. The Jackrabbit has 27 general-
purpose digital inputs/outputs available on headers J4 and J5—15 are bidirectional (one of
which is used by the RS-485 chip on BL1800 and BL1810 models), seven are inputs only
(one of which is used by the RS-485 chip on BL1800 and BL1810 models), and five are
outputs only (one of which is used by the RS-485 chip on BL1800 and BL1810 models),
as shown in Figure A-6.
