1.2.3 V74 FOUR PORT EIA-232 SERIAL
I/O MODULE
Ports on the V74 I/O module have RJ-45 connectors.
Most computers, printers, plotters, and modems do not
have modular connectors. Therefore, adapters are
required to convert DB-25 or DE-9 connectors to modular
connectors. Please refer to Section 14 for the required
adapter(s).
1.2.4 V77 ADM-1 ANALOG-TO-DIGITAL
CONVERTER MODULE
The V77 ADM-1 has a DB-25 female connector and
allows for 16 single-ended inputs or 8 differential
inputs. Figure 4 and Figure 5 show the single-ended
and differential input connections respectively.
