Faber M640, M1600 Network Controls via Sapera LT or GenICam Applications, Parameter Description

Parameter	Description
Network Configuration Mode	Specifies the Network Configuration Mode as either Automatic, Manual, or Optimize. In
	general use Optimize mode. Some computers, especially laptops, may require manual
	optimization of network parameters.
	The following parameters can be modified when Manual mode is selected.
Inter-Packet Delay (in sec)	Specifies the inter-packet delay, in sec. The range of permitted values is 0.000000 to
	0.065535. The inter-packet delay is the minimum time interval between two successive
	packets. This can be increased if the NIC is unable to keep up with packet arrivals (thus
	dropping packets–seen as video noise).
Packet Size (in bytes)	Specifies the maximum packet size, in bytes. The range of possible values is 576 to 1500,
	in increments of 4 bytes when the NIC does not support jumbo packet. The maximum is
	currently 9000 bytes when jumbo packets are supported (see "Increasing Adapter Buffers
	and Jumbo Frames" on page 24 to enable jumbo packets on the NIC). In most situations,
	use the largest possible packet size supported by your network elements. In order to
	support jumbo packets, all intermediate network elements must support them, otherwise
	they will simply be silently discarded and no image data will reach the PC.
Heartbeat Timeout (in Sec)	Specifies the heartbeat timeout, in seconds. The range of permitted values is 0.5 to 65, in
	increments of 0.001 seconds. This is used by the camera to ensure the PC application is
	still linked. If the heartbeat timeout expires, the camera will shutdown the connection to
	the current application.
Maximum Packet Resend	Sets the percentage of packets that can be resent for each frame. This is used to ensure
	the streaming data (including resends) does not exceed the Ethernet link capacity. As an
	example, a system capturing at 80 MB/s can allow 25% of packet resends without
	exceeding 100 MB/s (about the maximum capacity of a gigabit Ethernet link).

Network Controls via Sapera LT or GenICam Applications

Sapera

Genie Sapera parameters for Network Configuration:

NetworkConfigurationMode = {Automatic = 0, Manual = 1} InterPacketDelay = Minimum delay in µs between image packets PacketSize = Image packet size in bytes

HeartbeatTimeout = Heartbeat period (watchdog) in ms before camera disconnect MaximumPacketResend = Sets percentage of packets that can be resent per frame

In CamExpert, these parameters are available under the “GigE Vision” tab. See "Accessing Features with Sapera++ LT" on page 68.

GenICam features for Network Configuration:

PayloadSize = Size of the payload in bytes. This is the total number of bytes sent in the payload.

No packet headers.

Other networks parameters may be available through the 3rd party package used.
