8.8 Parallel Interface LPT1
The parallel interface LPT1 is a 25 pin DSUB socket. It supports EPP and ECP operating modes
(Plug & Play compatible) and the standard SPP mode.
To change these settings see the section "Integrated Peripherals".
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.
Because of general PC specifications, this interface should be handled with extreme
care with regard to EMC, location of cables etc.
