Interfaces
A4.3 Control and data interfaces
A4.3.1 CTRL/DATA/TTL/RELAY interface
This interface is multiple occupied and allows several functions:
– 2 x RS232/RS485 (switchable) for transparent data transmission
– Alternatively, the RS232 can be used for controlling the system
– 6 x TTL input/output, programmable
– 2 x relay output, programmable
The RS232 interface is used to configure and operate the MAGIC DC7/AC1
XIP System with a PC. For a connection to the PC you need a connection ca-
ble, where Pin 2 and Pin 3 are not crossed. Additionally, a Pin 5 GND has to
be connected.
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.
