5. Communication buffer and reset circuit
In the communication buffer circuit, the transmission signal (F-TXD)
and communication permit signal (F-DTR) from the copier is received
by the transistor array TD62504 (IC14), while the reception signal
(F-RXD) and communication request signal (F-DSR) transmitted from
the finisher to the copier is output from the IC14.
and communication permit signal (F-DTR) from the copier is received
by the transistor array TD62504 (IC14), while the reception signal
(F-RXD) and communication request signal (F-DSR) transmitted from
the finisher to the copier is output from the IC14.
The reset signal from the copier is also received by the IC14 and
input to the CPU’s reset terminal (active at L). In addition, the rever-
sion signal is input to the expansion I/O reset terminal (active at H).
For each signal, a protective diode is inserted between
input to the CPU’s reset terminal (active at L). In addition, the rever-
sion signal is input to the expansion I/O reset terminal (active at H).
For each signal, a protective diode is inserted between
+
5V and
GND.
