Chapter 5 Configuring the Client Adapter
Setting System Parameters
Power Save Mode
Sets your client adapter to its optimum power consumption setting.
Options: CAM, Max PSP, or Fast PSP
Default: CAM (Constantly Awake Mode)
Power Save Mode
Description
CAM (Constantly Awake
Mode)
Keeps the client adapter powered up
continuously so there is little lag in
message response time.
Consumes the most power but offers the
highest throughput. Is recommended for
desktop computers and devices that use
AC power.
Max PSP (Max Power
Savings)
Causes the access point to buffer incoming
messages for the client adapter, which
wakes up periodically and polls the access
point to see if any buffered messages are
waiting for it. The adapter can request
each message and then go back to sleep.
Conserves the most power but offers the
lowest throughput. Is recommended for
devices for which power consumption is
the ultimate concern (such as small
battery-powered devices).
Note
When you set Max PSP mode and
close ACU, the following message
appears the next time you open
ACU: “Maximum Power Save
Mode will be temporarily disabled
while you are running this
application.” While ACU is open,
Fast PSP mode is active. When
you close ACU, the card returns to
Max PSP mode.
Fast PSP (Power Save
Mode)
Switches between PSP mode and CAM
mode, depending on network traffic. This
mode switches to CAM when retrieving a
large number of packets and switches back
to PSP after the packets have been
retrieved.
Is recommended when power consumption
is a concern but you need greater
throughput than that allowed by Max PSP.
