Connecting the Interface

The Interface has a Centronics input and an RS232 output.

Centronics interface

The Centronics input of the Interface corresponds in its wiring

and signal characteristics to the input of a parallel printer. This

means that any normal printer cable permitting connection of

the data source with a Centronics printer can be used to

connect the Interface input to the data sender.

RS232 interface

Since peripherals also as a rule have RS232 ports configured as

DTE, the connection between the Interface and the peripheral

can usually be made using a serial printer cable configured as

follows:

Supply voltage

The Interface is powered using the supplied AC adapter. The

adapter provides a regulated voltage of 5 V ±5%. Commercially

available, unregulated AC adapters are not suitable for powering

the Interface.
