CABLING (Continued): Typical Connection Examples
V3.00 Iss 05-06 18 - 22
IRISEXP0204 Serial Data Expander - Front View
Connect 12~24VDC Power. to DC socket.
Data lines from up to 2 control devices connect to the 2 data input
ports.
Port 1 is colour coded Red=RS485 A(+) / Black=RS485 B(-)
Port 2 is colour coded Orange=RS485 A(+) / Black=RS485 B (-)
IRISEXP0204 Serial Data Expander - Rear View
Connect up to 4 cameras (or matrix switchers) to the rear panel.
Polarity for each channel is printed on the unit.
DC Power 12~24VDC
Centre Pin = Positive
Outer = Ground
Example 2: Multiple Camera / Controller
When connecting multiple cameras and/or controllers a serial data distributor
should be used. Iris offer the following models:
IRIS-EXP0204: 2 Controllers, 4 Slave devices (cameras / matrices etc)
IRIS-EXP0208: 2 Controllers, 8 Slave devices (cameras / matrices etc)
IRIS-EXP0216: 2 Controllers, 16 Slave devices (cameras / matrices etc)
If additional control devices are required, it is possible to daisy chain expanders
to acheive the desired amount of inputs. Contact Iris for further details.
Note: If you want to control cameras / matrices using a DVR or Web Server,
these must be connected as inputs.
Connect your input devices (IRIS595 or DVR for
example) to the front face as shown below.
Example:
IRIS595 Controller Data RS485 A(+) = Green -
Connect this to + terminal on the EXP0204, RS485
B(-) connect this to the - terminal.
Connect cameras (or matrices) to the rear face as
shown below. Again, ensure correct polarity is
observed (from the balun, the White wire is RS485
A(+) and the Braid is RS485 B(-).
