APPLICATION EXAMPLE „REAL“ RS-232 INTERFACE
The eDIP fits for direct
connection to a RS-232
interface with CMOS
level (VDD).
If you have an interface
with ±12V level, an
external levelshifter is
needed.

Application note
APPLICATION EXAMPLE: RS-485 INTERFACE
With an external converter (e.g.
SN75176), the EA eDIP can be
connected to a 2-wire RS-485
bus. Large distances of up to
1200 m can thus be
implemented (remote display).
Several EA eDIP displays can
be operated on a single RS-485
bus by setting addresses.
Application note
Adressing:
- Up to eight hardware addresses (0 to 7) can be set by means of Pins ADR0..ADR2
- The eDIP with the address 7 is selected and ready to receive after power-on.
- The eDIPS with the addresses 0 to 6 are deselcted after power-on
- Up to 246 further software addresses can be set by means of the ‘#KA adr’ command in the power-on macro (set eDIP
externally to address 0)
APPLICATION EXAMPLE: USB INTERFACE
With an external converter (e.g. FT232R from FTDI) the eDIP can be connected to an USB-Bus.
Virtual-COM-Port drivers are available for different Systems on the FTDI Homepage:
