3.3. Pre-Installation Checklist
The Passive CCTV Hub provides a centralized sixteen (16) port CCTV copper
twisted pair cabling solution.
1. The Passive CCTV Hub is used in a CCTV installation to manage the video,
power and control connections between the CCTV cameras and the head-end.
2. There are two (2) models of the Passive CCTV Hub; IC562A and IC563A.
The difference between the IC562A and IC563A is that the video portion of the
IC562A incorporates a video balun at each port and is connected to the DVR
via coaxial cable. The video portion of the IC563A is fully twisted pair on the
input and output and connected to the DVR via twisted pair cable. In order to
convert from twisted pair back to coax, a CCTV video balun is connected at
each DVR port.
3. The products feature a switch at each port to select between Pass-Thru Mode
(IC452A compatible) or Power-Thru Mode (IC560A/IC561A compatible)
depending on the cabling configuration.
4. The Passive CCTV Hub works in conjunction with Black Box’s other CCTV
products including the IC440A, IC444A, IC453A, IC452A, IC451A, IC560A,
IC561A, IC454A and IC455A). The passive CCTV Baluns are connected at
the CCTV camera.
5. The Passive CCTV Hub works with CCTV cameras that have built -in twisted
pair baluns. It may be necessary to reverse the polarity of the wires first.
Distance performance may vary.

3.4. Physical Installation
The Passive CCTV Hub is a 1U, 19” rackmount unit. The factory default switch
settings of each port is Pass-Thru Mode (IC452A).
1. Select the final destination for the product in the relay rack and install the unit
using standard rackmount screws.

Passive CCTV Hub Installation Guide
3.5. Installation Procedure – Model IC562A
The Passive CCTV Hub, Model IC562A features BNC connectors on the video
portion of the device, thereby allowing it to be connected directly to the DVR via
coaxial cable. In order to install the product in this configuration, please follow the
steps below:
1. Install the Passive CCTV Hub in its final location. Please verify that the distance
between the rack and cameras are within Black Box specifications.
2. Connect a Black Box passive CCTV Balun (Black Box p/n IC440A, IC444A,
IC452A, IC451A, IC560A or IC561A) to each CCTV camera video output.
Please refer to the appropriate CCTV balun installation guide for details.
3. Connect one Cat5 cable from each camera to one of the modular RJ45 ports on
the front of the Passive CCTV Hub (fig 5). Please ensure that EIA 568 wiring
and straight-through polarity is respected between the CCTV balun and the
rack. The use of other Cat5 connection hardware such as patch panels and 110
blocks may be used.

Passive CCTV Hub Installation Guide
Port Switch Settings:
4. For each camera port, determine whether video, power and/or control is to be
transmitted via the same Cat5 cable. If only video is to be transmitted, then the
Power/Control terminals and port switch may be disregarded.
5. In order to transmit video on one (1) twisted pair, remote power on two (2)
twisted pairs and control on one (1) twisted pair, set the port switch to PassThru Mode (IC452A) using a small flathead screwdriver, as shown in fig 6.
Ensure that there is a CCTV Pass-Thru Balun (IC452A) at the camera.
Figure 6: Port Setting – Pass-Thru Mode (IC452A)
6. In order to transmit video on one (1) twisted pair and remote power on three (3)
twisted pairs, set the port switch to Power-Thru Mode (IC560A/IC561A) using
a small flathead screwdriver (fig 7). Ensure that there is a CCTV Power-Thru
Balun (IC560A or IC561A) at the camera.

Output Connections:
Video:
7. Connect one coax cable between each video output port on the rack and the
DVR video input (fig 8).
Figure 8: Video connection, Model IC562A
Remote Power:
8. If remote power is being transmitted to the camera, verify that the distance
between the camera and the hub is within Black Box specifications. Please
consult the distance charts at the back of the installation guide. When the port
switch is set to Pass-Thru Mode (IC452A), two (2) twisted pairs are used for
remote power. When the port switch is set to Power-Thru Mode
(IC560A/IC561A), three (3) twisted pairs are used for remote power thus
supporting greater distance.
9. Connect two (2) wires between the power terminals of the hub to the remo te
low voltage power supply (fig 9). It is recommended to use a Class II
power supply with fuse protection on each output port.
Figure 9: Remote power connection, Model IC562A

PTZ Control:
10. If PTZ Control is to be transmitted to the camera, verify that the distance
between the camera and the hub is within the distance specifications for sending
PTZ control over twisted pair. Consult the PTZ equipment vendor for maximum
distances. Please ensure that the port switch is set to Pass-Thru Mode
(IC452A). When the port switch is set to Pass-Thru Mode (IC452A), one (1)
twisted pair is used for PTZ control. For optimum results, it is recommended to
use control protocols such as RS -422, RS-485 or Bi-phase. Due to crosstalk
issues, RS-232 is not recommended.
11. Connect two (2) wires between the PTZ controller and the “Control” terminals
on the hub (fig 10).

3.6. Installation Procedure – Model IC563A
The Passive CCTV Hub, Model IC563A features screw terminal connectors on the
video portion of the device, thereby allowing it to be connected via twisted pair to
the head end equipment (DVR). Video baluns, such as the IC444A, must be used
at the DVR to convert back to coaxial cable. In order to install the product in this
configuration, please follow the steps below:
1. Install the Passive CCTV Hub in its final location. Please verify that the distance
between the cameras and the head end are within Black Box specifications.
2. Connect a Black Box passive CCTV Balun (Black Box p/n IC440A, IC444A,
IC452A, IC451A, IC560A or IC561A) to each CCTV camera video output.
Please refer to the appropriate CCTV balun installation guide for details.
3. Connect one Cat5 cable from each camera to one of the modular RJ45 ports on
the front of the Passive CCTV Hub (fig 12). Please ensure that EIA 568 wiring
and straight-through polarity is respected between the CCTV balun and the
rack. The use of other Cat5 connection hardware such as patch panels and 110
blocks may be used.
