Section 6: Using the Printer Interface
Using an IBM AT Personal Computer (RS-232C)
If you are using an IBM AT or compatible computer, use a 9-pin to 25-pin EIA
RS-232C cable.
We recommend one of the following for a 9-pin to 25-pin cable:
• IBM P/N 6450242 (254 mm or 10 in.)
• IBM P/N 6450217 (3 m or 10 ft.)
The following illustration shows the pin assignments for the 9-pin to 25-pin
RS-232C serial cable.
Serial Communication Parameters (RS-232C)
The acceptable values for serial communications parameters follow.
Voltage Level Range
The maximum voltage level range for control lines or data lines is from
± 25 positive V dc to ± 25 negative V dc.
