To connect an output To disconnect an output
Extract the plugable lead
corresponding to the output
that you wish to connect from
the connector on the rear
panel of the device.
Disconnect the plugable lead from
the connector located on the rear
panel of the device.
Introduce the stripped cable
from the device into the lead,
screwing this in firmly. Select
the connector identified as
“NO” if the connection type is
normally opened or “NC”, if
the selected connector is
normally closed.
Unscrew the lead cable and
subsequently remove it.
Plug the lead into the
connector on the rear panel of
the device.
Plug in the lead to the connector
located on the rear panel of the
device.
I - 2.2.4. Input / Output expansions
VisorNet 4c permits you to expand the number of inputs/outputs that are handled
through the VisorIO expansion modules. Each module includes six inputs and six
outputs with similar characteristics to the internal inputs/outputs of the device itself.
You can link various expansion modules together through an RS-485 bus. The first
module in the link is connected to a VisorNet 4c through an RJ45 connector from the
RS-485 port. The cable connecting the first module in the link with the VisorNet 4c
is an RJ11-RJ11 crossed cable. Only the center two wires of the six wires available
are used.
To connect the first module in the link to VisorNet 4c you connect one end of the
cable to the VisorIO module CON1 connector. The other end is connected to the
RJ45 connector labeled as RS-485.
You can find further information on how to connect and configure the Visor10
modules link in the Dm251-I “VisorNet system reference guide”.
I - 2.3. Connecting the RS-232 and RS-485 peripherals
The RS-232 and RS-485 connectors permit you to connect security equipment such as
mobile cameras and matrixes from other manufacturers to the VisorNet 4c.
The RS-232 bus conector is a DB-9 with the following signal distribution:
DB9 MALE RS -232
5, RACK GND
2 RXD
3 TXD
