Setting up
Making Sub-D connection
The connection, e.g., to the control unit is made
using an adapter cable with Sub-D connector
(for pin assignments see ”Technical Data“,
p. 5).
Plug the 25-pin connector (female) of the
adapter cable onto the OZDV 114 B and lock
it using the two locking bolts of the module.
Power supply
The supply of +5 V DC (stabilised) is provided
via the Sub-D connector.
Warning!
Only supply the system with a safety extra-
low voltage in accordance with IEC 950/
EN 60 950/VDE 0805.
Making optical fibre connections
Plug the optical fibre cable with BFOC plug
onto the OZDV 114 B. Connect the two com-
ponents using optical fibre cable such that in
each case an input is connected to an output
(cross over connection).
Fitting/Removing module
Fit the module by hanging it and snapping it
into place on a standard DIN rail.
The module is removed by pulling on the
locking catch.
Description
OZDV 114 B is an asynchronous full duplex
transmission system for symmetrical V.11
(RS 422) interfaces. It replaces all five-wire
connecting cables.
A transmission system consists of two digital
transmission modules OZDV 114 B.
Data rate 0 to 6.5 Mbit/s
The system is able to recognise a restart signal
even after long transmission interruptions.
Power supply
The module is supplied with +5 V DC (stabili-
sed) from the terminal unit connected via the
25-pin Sub-D connector.
