magnetically loaded surroundings (e. g. in industrial applications) be induced in the interface cables
and thus destroy connected electrical circuits. By means of jumpers the data lines RxD0 (PortE.0),
TxD0 (PortE.1) and RxD1 (PortD.2), TxD1 (PortD.3) can through the Controller be connected to the
level converter. During quiescent condition (no active data transmission) a negative voltage of several
volts can be measured on Pin TxD against GND. RxD is of high impedance. The 9 pole SUB-D
socket of the application board carries RxD0 on Pin 3 and TxD0 on Pin 2. Pin 5 is the GND
connection. No handshake signals are being used for serial data transmission. The second serial
interface is lead to a 3 pole pin strip. Here RxD1 occupies Pin 2, TxD1 occupies Pin 1 while Pin 3 is
GND.
The cable with connection to the NRZ Pins TxD, RxD and RTS may have a length of up to 10
meters. It is recommended to use shielded standard cables. When using longer lines or non-
shielded cables interferences may detract correct data transmission. Only use cables of which the
pin assignments are known.
Never connect the serial transmission outputs of two devices directly together! Transmission
outputs can usually be identified by their negative output voltage in quiescent condition.
Testing Interfaces
The 4 pole pin strip X16 is to be used for testing purposes only and will not necessarily be armed
with components of any kind on every application board. For the user this pin strip is of no
importance.
One further testing interface is the 6 pole pin strip (two rows at 3 pins each) at the lower right next
to
JP4
. This pin strip too is only meant for internal use and may likely no longer be fitted with
components in future board series.
