COM0 / COM1 Serial Interfaces
The System is equipped with two serial interfaces
without
handshake lines which can be set
up individually. Data exchange can take place via RS232c (V.24) or RS422 (V.11) signal
levels. The signals can be used, for example, to transmit time telegrams to other computers.
Using the COM0 interface as Remote-Interface (RC Systems) and COM1
interface as synchronisation interface (Sub-Master Systems) the interfaces
are not available for any other functions.
The parameter settings have no effect on the serial interface COM1 in case
of synchronisation of System via serial interface by the
hopf
Master/Slave
string. At this, the parameters are firmly adjusted to 9600baud, 8 data bit, no
parity and one stop bit.
Various data strings are available. Customer-specific data strings are available on request.
The following settings can be made separately for each serial interface.
Alternatively, System pulses can also be transmitted via the serial interface
hardware (see
Chapter 6.1.2.8 Mode Byte 2 / Bit7: Output Mode DATA

Configuration of the Serial Interfaces / Pulse Output
The parameterization and functionality of the serial interfaces respectively the selection of
pulses is described below.
6.1.1 Serial Transmission Parameters
The interfaces are parameterized via the keypad. The baud rate, data bit, stop bit and parity
settings are made by pressing the
ENT
key and selecting the
SET
menu.
