Video Data Rate
Options: Full, 32 kbps, 64 kbps, 128 kbps, 256 kbps, 384 kbps, 512 kbps, 1 Mbps,
2 Mbps
Factory Default: Full
The Video Data Rate option provides the ability to control the amount of bandwidth that is used
when transmitting video data to ADPRO VideoCentral. Bandwidth is a limited resource and is
shared between all users on a network.
The Video Data Rate acts like a ‘throttle’ and is useful if the network administrator needs to limit
the amount of bandwidth used by certain devices. Refer to your Network / System Administrator
for further advice regarding any bandwidth restriction or limitation.
Note: This data rate applies per user: if two users are connected at 32 kbps, the total
bandwidth used would be 64 kbps.
Serial Communication Properties
There are two Serial Communication Ports for analog telephone line or digital line connection for
communications with ADPRO VideoCentral. Modems are used for analog line (PSTN)
connections and terminal adaptors (TA) for digital lines (ISDN). The COMMS 1 port is fitted with
a 25-pin D male connector. The COMMS 2 port is a 9-pin D male (refer to Comm Port 2
Connection on page 30).
Note: The COMMS 2 port can be used for direct connections to a PC for local setup and
for software upgrades. A Null Modem driver is provided in the ADPRO VideoCentral
installation CD.
Refer to Tech-Tip 11460_00–Windows XP SP2 Issues (available on the website:
www.xtralis.com/adpro) for more information on the use of the Null Modem Cable.
The Serial Communications Port 1 Settings and Serial Communications Port 2 Settings
menus allow the operating parameters of the two serial ports to be configured to match the
model of modem or terminal adaptor used.
