13.5 IF 962-LPT Interface Submodule for M7-300/400;
(6ES7962-4AA00-0AC0)
Characteristics
The IF 962-LPT interface submodule contains an AT-compatible parallel (LPT) port
for connecting a printer with Centronics interface. The IF962-LPT submodule can
also be used as a bi-directional data interface. There is a 25-pin sub D socket
connector on the frontside of the submodule for plugging in the connecting cable.
Up to four LPT ports can be accessed on AT I/O addresses in one programmable
module using standard PC drivers. This also includes LPT ports located on the
programmable module itself and those located on expansions. The IF 962-LPT
interface submodules can be operated in the AT-compatible address area and, if
special drivers are used, also in the M7-300/400-reserved address area.
The cable length on the IF 962-LPT interface submodule should not exceed
approximately 3 m.
