(6ES7962-1BA00-0AC0)
Characteristics
The IF 962-VGA interface submodule is used to connect a keyboard and a VGA
screen. The interfaces to the keyboard and the screen are AT-compatible.
As an alternative to a “normal” AT keyboard, a keyboard with an integrated
trackball can be connected (for example, the PG 740 keyboard).
The IF 962-VGA interface submodule is designed for the local area and the
distance to the I/O devices should not exceed approximately 2.5 m.
