108 s Serial Interface Board 2 OP7100
Introduction
The SIB is an interface adapter used to program the OP7100. The SIB is
contained in an ABS plastic enclosure, making it rugged and reliable. The
SIB enables the OP7100 to communicate with Dynamic C via the Z180’s
clocked serial I/O (CSI/O) port, freeing the OP7100’s serial ports for use
by the application during programming and debugging.
The SIB’s 8-pin cable plugs into the target OP7100’s processor through an
aperture in the backplate, and a 6-conductor RJ-12 phone cable connects
the SIB to the host PC. The SIB automatically selects its baud rate to
match the communication rates established by the host PC (9600, 19,200,
or 57,600 bps). However, the SIB determines the host’s communication
baud rate only on the first communication after reset. To change baud
rates, change the COM baud rate, reset the target OP7100 (which also
resets the SIB), then select
Reset Target
from Dynamic C.
Chapter 2 provides detailed information on connecting the SIB
to the OP7100.
The SIB receives power and resets from the target OP7100 via the 8-pin
connector J1. Therefore, do not unplug the SIB from the target OP7100
while power is applied. To do so could damage both the OP7100 and the
SIB; additionally, the target may reset.
The SIB consumes approximately 60 mA from the +5 V supply. The target-
system current consumption therefore increases by this amount while the
SIB is connected to the OP7100.
When the OP7100 is powered up or reset with the SIB attached, it is
automatically in the program mode. To operate the OP7100 in the run
mode, remove power, disconnect the SIB, and re-apply power to the
OP7100.
Never connect or disconnect the SIB with power applied to
the OP7100.
