Symptom - "Connection Lost" Message in GEVPlayer Application
During operation, the iPORT SB-Pro IP engine can lose connection to the GEVPlayer application,
Heartbeat Timeout Too Restrictive
In the GEVPlayer application, the "Connection Lost" message can indicate restrictive settings for the
heartbeat synchronization between the network PC and the iPORT SB-Pro IP engine. In the GEVPlayer
application, check the heartbeat settings in the
HeartbeatInterval parameter under the Communication
Control option (button) for the PC heartbeat interval. Then, verify the GevHeartbeatTimeout
parameter under the GEV Device Control option (button) for the IP engine’s heartbeat interval.
The HeartbeatInterval parameter setting for the network PC must be at least double (2x) the Gev-
HeartbeatTimeout parameter setting for the iPORT SB-Pro IP engine to avoid a timeout.
Symptom - Dropped Packets
During operation, GEVPlayer, NetCommand, or another application created using the eBUS SDK may
drop packets from the iPORT SB-Pro IP engine
Insufficient PC performance
The PC being used to receive images from the IP engine may not perform well enough to handle the
data rate of the image stream. The eBUS Universal Pro driver reduces the amount of PC resources
required to receive images, and is recommended for those applications which require high throughput.
Should the application continue to drop packets even after the installation of the eBUS Universal Pro
driver, a PC with better performance may be required.
Insufficient NIC performance
The Network Interface Card (NIC) being used to receive images from the IP engine may not perform
well enough to handle the data rate of the image stream. For example, the bus connecting the NIC to the
CPU may not be fast enough, or certain default settings on the NIC may not be appropriate for reception
of a high-throughput image stream. Examples of NIC settings which may need to be reconfigured
include the number of Rx Descriptors, and the maximum size of Ethernet packets (Jumbo Packets).
Additionally, your NIC may be known not to work well in high-throughput applications. Refer to the
Network Adapters Knowledge Base Technical Note , available on the Pleora Support Center.
