Interfaces
A4.7 MAGIC DC7/AC1 XIP RM
Additionally, for the RM version the CTRL/DATA/TTL/RELAY interface
(see TAB. 11) is splitted. All other interface functions are identical.

A4.7.1 DATA/CONTROL & DATA/PAD interface
The DATA/CONTROL interface can be used either as control interface to the
PC (RS232) or as transparent data interface (RS232/RS485, switchable).
To connect a PC, a 1:1 connection cable is required, where Pin 2 and Pin 3 are
not crossed. Additionally, Pin 5 has to be connected.
The DATA/PAD interface can be used as transparent RS232/RS485 data in-
terface (switchable) only.
NOTE
Please note that the function - input or output - of the Pins RXD1/2 and
TXD1/2 are determined by the interface type DCE or DTE. The labelling of
the Pin is always RXD for Pin 2 and TXD for Pin 3.
For both data interfaces RXD serves always as receive path and TDX serves
always as transmit path.
