Portable Sur-	Portable Surveyor 10/100 Ethernet Analyzer Card is an adapter/analyzer
veyor 10/100	card for 10/100 Ethernet networks in a notebook PC environment. Portable
Ethernet Analyzer	Surveyor 10/100 Ethernet Analyzer Card adapters can be used to capture,
Card	transmit, or monitor. When using an Portable Surveyor 10/100 Ethernet Ana-
	lyzer Card adapter, all counters are supported. The default mode for Portable
	Surveyor 10/100 Ethernet Analyzer Card adapters is Capture + Monitor; the
	Capture+Transmit mode is not supported. All Surveyor real-time functions
	are available.
	The effective rates at which an Portable Surveyor 10/100 Ethernet Analyzer
	Card adapter can capture and monitor is limited because these functions are
	performed in software rather than hardware. Use Portable Surveyor 10/100
	Ethernet Analyzer Card adapters in Monitor only or Capture only mode to
	improve performance. Capture rates can approach full-line rate for 10 Mbps
	networks if other PC functions are limited.
NDIS	Surveyor NDIS supports up to four adapters. The first adapter found during
	system initialization is seen by Surveyor software as module #1, the second
	as module #2, and so on.
	Standard Ethernet or Token Ring adapters can be used to capture, transmit,
	or monitor, but have severe performance constraints. The effective rate at
	which an NDIS module can capture or monitor is limited because it must per-
	form these functions in software rather than hardware. An NDIS adapter is
	often used in Monitor only mode to improve performance, since NDIS adapt-
	ers cannot capture at full line rate. When using an NDIS adapter, check the
	Information tab to see information about what counters are supported. Each
	manufacturer supports a different set of counters. The default mode for NDIS
	adapters is Capture + Monitor.
Multi-port Taps	Taps are fault-tolerant wiring devices that provide connections for analyzer
	devices. A Finisar multi-port tap shows as a “resource” to the Surveyor soft-
	ware, but is only used to select a LAN segment for monitoring and LAN anal-
	ysis functions.
Switches	Switches are wiring devices that provide connections for analyzer devices.
	The switch shows as a “resource” to the Surveyor software, but is only used
	to select a LAN segment for monitoring and LAN analysis functions. 4, 6, or
	8-port Datacom Switches for 10/100 or Gigabit Ethernet are supported.

Synchronized Resources

Synchronized resources are multiple hardware devices (two THGm) that have been connected so that they use the same clock timer. Synchronized devices display in the Resource Browser as a unique resource. For example, if the two THGm modules in a full-duplex THGs are synchronized, then the Resource Browser shows three resources available within the THGs; the first THGm, the second THGm, and the synchronized configuration of both THGm modules together.
