This section contains a list of terms that appear in this user guide, with their definitions.
10/100Base-T
Ethernet that uses unshielded twisted pair (for example, UTP - Cat 5) cable, in which the
amount of data transmitted between two points in a given amount of time is equal to either
10 Mbps or 100 Mbps.
A
Address Resolution Protocol (ARP)
A protocol for assigning an IP address to a device based on the MAC (Media Access Control),
or physical machine address of the device, that maintains a table showing the correlation
between the two.
Alarm relay
A single pole, single throw relay, which can be used with a relay-controllable audible siren or
any other alarm.
Alarm status
On the PCS4 web page, reflects the state of the monitored condition. It may be inactive,
active, or silenced.
AWG (American Wire Gauge)
A standard measurement for wire conductor diameter.
C
Condition
A state for which the PCS4 is being monitored. When a monitored condition is met, the
PCS4 may sound an alarm or send an e-mail message, depending on how the system has
been configured (via the front panel or the Monitor web page). Examples of conditions that
can be monitored include Receptacle Off, Any Change, or Reference: None.
Custom web page
Any file that can be loaded into an IPL T PCS4 and served by the PCS4 internal web server.
The web page provides a way to control and monitor the PCS4 output power receptacles.
This is true with or without an accompanying event script. Any number and size of graphics
can be used, but if they are too large to fit in the PCS4 nonvolatile memory, you can create
web pages so that they can be served from another web server. If you install Microsoft
Internet Information Services (IIS) on your desktop, you can serve any page on its hard disk.
The IPL T PCS4 functions like a little computer with a web server — you can use it for
various web-based tasks.
