6. Repeat steps 3 through 5 to set the other
date/time fields, as needed.
7. Do one of the following:
−
To save the new date/time settings and then
exit, return the keyboard to Operate mode.
−
To exit without saving the new settings, press
Clear , and return the keyboard to Operate
mode. The monitor displays the original
date/time settings.
Setting Port Configurations
Each MegaPower CPU provides the following port
types:
•
Keyboard
•
Recorder
•
Satellite
•
Alarms (1–1024)
•
Alarms (1025–2048)
•
Alarms (2049–3072)
•
Alarms (3073–4096)
•
Terminal
•
Auxiliary
•
Video Loss Detection (1–1024)
•
Video Loss Detection (1025–2048)
•
Video Loss Detection (2049–3072)
•
Video Loss Detection (3073–3200)
The Port Configuration setup allows you to identify
the device type (keyboard, port expansion module,
and others), baud rate, and other communications
parameters of each device connected to a port on
the CPU.
Important: The MegaPower CPU can support up to
128 keyboards using port expansion modules. Port
expansion modules convert a single port into four
ports. When a port expansion module is connected to
a port, port numbering adds an alpha character (a, b,
c, d) to each port number; for example, port one
becomes ports 1a, 1b, 1c, 1d; port two becomes
ports 2a, 2b, 2c, 2d, and so on.
Click on the System – Port Configurations link in the
Explore menu to begin. The following screen
appears.

To configure ports, complete the following fields:
•
Port No. – Identifies the number of the port on the
CPU to which the device is connected. Each
available port number expands by four when a
port expansion module is connected (see
Important explanation above).
•
Type – Identifies the device connected to the
port. A predefined dropdown list offers the
following options: Keyboard, Recorder, Satellite,
Alarms, Terminal, Auxiliary, and Video Loss
Detection.
•
Baud Rate – Identifies the data transmission rate
(in bps) of the connected device. Choose from the
following: 300, 1200, 2400, 4800, 9600, 19200,
and 38400.
•
Parity – Detects transmission errors. Choose
from the following list: None, Odd, or Even.
•
Data Bits – Identifies the number of bits in each
packet of data being transferred. Choose either 7
or 8.
•
Stop Bits – Signals the end of each character
being transmitted. Choose either 1 or 2.
•
Location – Identifies the physical location of the
device. You can type up to 16 characters.
However, this field is for informational purposes
only, and any device location entered in this field
is not transferred to the MegaPower CPU.
Configuring the Dome/PTZ
Device Direct Connection
The Dome/PTZ (Pan/Tilt/Zoom) Device Direct
Connect Configuration screen allows you to
configure the MegaPower CPU to specify the
physical connections and protocol that enable
commands to be sent to domes connected to the
system video inputs.
Click on the System – Direct Dome/PTZ Connections
link in the Explore menu to begin. The following
screen appears (Figure 62).
