Connecting the OP7100 to a Host PC
1. Unplug any power supply connected to the OP7100 and remove the
back cover from the OP7100 assembly. The back cover is attached
with the two screws shown in Figure 2-3.

2. Establish a serial communication link. A PC “communicates” with the
OP7100 via Serial Port 0 or the Clocked Serial Input/Output port on
the OP7100’s Z180 microprocessor. There are two options for the
serial communication link.
Option 1 (via optional SIB)—Connect an RJ-12 cable between the PC
and the SIB. An RJ-12 to DB9 adapter is included for DB9 PC COM
ports. Remove any jumpers that may be installed on the OP7100’s
header J4 and plug the SIB’s 8-pin connector onto header J4 as shown
in Figure 2-4. Make sure that pin 1 on the ribbon cable connector (on
the striped side) matches up with pin 1 on J4 (indicated by a small
white circle next to the header).
Option 2 (directly)—Place a jumper across pins 1–2 of header J4 on the
OP7100 as shown in Figure 2-5. Connect the PC COM port to the DB9
jack on the OP7100, header J7, using the DB9 to DB9 serial cable
supplied with the Tool Kit.
3. The OP7100 is now ready for programming. The power supply may be
plugged in and turned on.
