134 | NAVISET ADMINISTRATOR 2 USER’S GUIDE
Question: How much network bandwidth does NaViSet Administrator use?
Answer: Communications to each device uses a minimal amount of network bandwidth - typically several kilobytes for
most operations.
Question: How long would it take to perform an operation on a large number of devices?
Answer: NaViSet Administrator can communicate to multiple different devices in parallel, which speeds up operation
by allowing simultaneous connections, and allows more operations to be performed while waiting for other devices to
respond to commands. Up to 30 connections can be used by selecting Maximum simultaneous network connections
in the application Preferences (see page 110).
Assuming that all 30 connections are used with the maximum possible efciency, then operations on all devices will
complete at 30 times the speed of performing the operation on all devices in serial using one connection. Depending
on the device, connection type, and operation being performed, operation times are typically between 5 seconds to 1
minute.
Example: Approximately how long would it take to power off 1000 displays?
Assuming a power off operation takes 15 seconds to perform on a device, if performed serially using one connection
the total time would be about 15 seconds x 1000 = 15000 seconds (over 4 hours). If 30 connections are used, then the
time is 15 x 1000 ÷ 30 = 500 seconds (just over 8 minutes). It is assumed that no other operations are being performed
at the same time.
Question: Is it possible to connect to a display that is connected via RS232 to the local computer?
Answer: Yes. Install and congure the LAN to RS232 Bridge application on the local computer. Add the display to the
device tree in the same way as any other device, but use either the computer’s actual IP address, network name, or
the IP address 127.0.0.1.
