5 Reset
The Main Board provides a power-on reset signal which is driven by an MB3771 integrated circuit.
This circuit asserts the power-on reset signal when the Main Board is inserted into a PCMCIA slot, or
when the PC it is attached to is powered on. A second reset signal is provided by the Zilog
Z1601720ASC PCMCIA interface; this signal will reset the TMC2074 when asserted; it is also provided
to the CN2 connector.
6 Monitoring the CMI Decode Signal
When the Hub Function is disable, the CMI decoded signal (an RZ-coded signal) can be monitored on
the TP4 test point connection on the RS485 Board. Note that TP4 is not mounted.
