Troubleshooting
Out of the Box
Check the items mentioned in this section before starting development.
Verify that the OP7100 runs in standalone mode before connecting any
devices.
Verify that the entire host system has good, low-impedance, separate
grounds for analog and digital signals. The OP7100 might be connected
between the host PC and another device. Any differences in ground
potential from unit to unit can cause serious problems that are hard to
diagnose.
Do not connect analog ground to digital ground anywhere.
Double-check the connecting ribbon cables to ensure that all wires go
to the correct screw terminals on the OP7100.
Verify that the host PC’s COM port works by connecting a good serial
device to the COM port. Remember that COM1/COM3 and COM2/
COM4 share interrupts on a PC. User shells and mouse drivers, in
particular, often interfere with proper COM port operation. For
example, a mouse running on COM1 can preclude running Dynamic C
on COM3.
Use the supplied Rabbit Semiconductor power supply. If another power
supply must be used, verify that it has enough capacity and filtering to
support the OP7100.
Use the supplied Rabbit Semiconductor cables. The most common fault
of user-made cables is failure to properly assert CTS. Without CTS
being asserted, theOP7100’s RS-232 port will not transmit. Assert CTS
by either connecting the RTS signal of the PC’s COM port or looping
back the OP7100’s RTS.
Experiment with each peripheral device connected to the OP7100 to
determine how it appears to the OP7100 when powered up, powered
down, and/or when its connecting wiring is open or shorted.
The frame ground and 0 V are connected internally via a jumper on
header JP5. Remove the jumper if this connection causes problems or
is otherwise not required.
