Serial Communication Ports, Continued
In the Serial Port tab of Setmax, the user needs to configure the ports depending on the
site requirements. The following are the four port types that are relevant for VideoBlox.
1. VB-IO/Pretitler
2. VB-PTZ
3. VB-Alarm/COutput
4. VB-Auxiliary
VB-IO/Pretitler: The serial port that is configured should be of type VB-IO/ Pretitler, if it
is connected to input cards, output cards, titler cards or MVT (generally used for
Pretext). Refer to the VideoBloX manuals of the Input, Output cards and MVT for
configuring the same.
VB-PTZ: The serial port that is configured should be of type VB-PTZ, if PIT is connected
to it. This port type is used for the control of PTZ cameras. This is analogous to MAXPRO
Subrack. PIT has three modes. PIT should be configured for PTZ mode. Address of PIT
should be set to zero (broadcast). The serial settings should match the settings in
Setmax. Based on the PTZ camera that is controlled by the PIT, the dip-switches should
be set. All settings in PIT are done using DIP switches.
VB-Alarm/COutput: The serial port that is configured should be of type VB-Alarm/
COutput, if PIT is configured in the Alarm Concentrator mode and is connected to this
port. PIT when configured in Alarm Concentrator mode will be used to support external
alarms and control Auxiliary Control Outputs (relays). The address of the PIT shall again
be 0. I2C16IN and I2C16OUT boxes have to be connected to the I2C port of PIT. These
I2C boxes have dip-switches for setting the address. Each box can support either 16
Alarms (I2C16IN) or 16 External Alarms (I2C16OUT). For e.g., to configure that particular
box to support alarms from 1-16, the address of the box should be set to 1 and address
should be set to 2 for supporting alarms 17-34. For more configuration details, refer to
the respective manuals.
VB-Auxiliary: This serial port is used when a third party system is required to access the
functionality of the switcher (like Access Control System, EBI etc.).
Note: The devices, their details, baud rate, parity, stop bits and data bits for
communication depends on the devices that are connected to the system. Please
refer to the VideoBloX manuals.

Serial Ports
This represents the type of the device to be connected to the port.
1. Backplane or IO Cards. 2. PIT – PTZ. 3. PIT – Alarms &
Control Outputs. 4. VB-Auxiliary port
For Backplane or IO cards port, these two represent the video
loss source device type. 0 & 0 represents that the video loss
source device is Input cards. 0 & 1 represents that the video loss
source device is Concentrator. 1 & 0 represents that the video
loss source device is MVT or pretext devices. 1 & 1 represents
that there is no device as video device loss source.
