3.3.3.5
RS422/V11, SS97 Option RS422
The interface signals generated in the microprocessor and in the application’s
specified IC are connected to the driver IC1. This IC converts the TTL signals on the
microprocessor side to the RS422 / V.11 levels on the I/O side and vice versa. On the
I/O side the signals are connected to the I/O plug X2 via coils.
SS97
The interface signals generated in the microprocessor and in the application’s
specified IC are connected to the driver IC1.
This IC converts the TTL signals on the microprocessor side to the SS97 levels on
the I/O side and vice versa.
On the I/O side the signals are connected to the I/O plug X3 via coils.
