VIDEO OUT
Video output for transmitting analog video signal to an analog video display, analog
video matrix, or analog video recording device. You can connect an analog monitor to
this port for viewing ioimage Unit video.
5.
RS232/485
Serial port that can be split-out for up to two connections (RS232 and RS485 support).
Primarily used for connecting PTZ control. Note Channels 1 & 2 are on the first Block
IP configurations and Channels 3 & 4 are on the second Block IP configurations.
For more information on the RJ45 pin-out for the back panel connections, see the
section (page 64).
Note
: An adapter cable RJ45 to 2 x RS232 DB9 + 1 RS485 lead wires can be purchased as
a separated accessory
Warning
: The RS232 standard specifies a maximum open-circuit voltage of +/-25 volts.
Exceeding this voltage can cause permanent damage to the unit.
Warning
: The RS485 standard specifies a maximum voltage of +12 V and -7 volts.
Exceeding this voltage can cause permanent damage to the unit.
6.
POWER
The power plug for connecting the IEC cord (C13/C14).
7.
Alarm Inputs and Relay Outputs
Alarm Inputs
(1-8) Terminal-block-connector port for plugging in terminal block connectors. Supports
up to four input connections (a set of two wires for each) for external relay devices. The
right terminal of the two is a grounded common. For example, fire sensors, PIR, fence
sensors, etc. For more information and channel assignment, see the
External Device Interfaces – ioibox Channel Assignments
(page 22).
Relay Outputs
Terminal-block-connector port for plugging in terminal block connectors. Supports
output of optoisolated signal for up to two connected external relay devices. For
example, an electrical door lock relay.
NO1, NO2 are leads for “NORMALLY OPEN” relay configurations
NC1, NC2 are leads for “NORMALLY CLOSED” relay configurations
C1, C2 are leads for COMMON wire relay configurations for either NC or NO relay. For
more information and channel assignment, see the
section
(page 34) and
External Device Interfaces – ioibox Channel Assignments
(page 22).
8.
Protective Earth Terminal
ioibox must have the external protective earth terminal permanently connected to
protective earth according to local regulations and codes. For more information, see
Connecting the External Protective Earth Terminal
(page 46).
