7.8 Parallel Interface LPT1
The parallel interface LPT1 is a 25 pin DSUB socket. It supports EPP and ECP operating modes
(Plug & Play compatible) as well as the standard SPP mode.
To change these settings, see the "BIOS settings" section in Chapter 6 "Software".
Note: Provit IPC parallel interfaces are equipped with a protective circuit in order to conform with
requirements for operating in industrial environments. This can possibly lead to limitations in
regard to the maximum transfer rate.
