I want to restore the RGS Receiver properties to factory defaults. Uninstall and reinstall the RGS Receiver.
Troubleshooting network timeouts
RGS uses TCP/IP over a standard computer network to transmit data. Although TCP/IP is a reliable transport
mechanism, it does not guarantee network packet delivery. The TCP/IP network stack performs well on a
relatively stable network. However, network issues beyond RGS can affect the probability and timing of
network packet delivery. Possible network issues include:
Network over-subscription, resulting in congestion and packet loss
CPU utilization by other processes and tasks, starving the TCP/IP network stack
Incorrectly configured or malfunctioning network switches, routers, and network interfaces
A disconnected network cable
To deal with such network issues, the RGS Receiver and Sender both support network timeout mechanisms to
provide notification to the user of network issues.
RGS Receiver network timeout
RGS provides two user-settable RGS Receiver timeout properties to allow you to optimize RGS for your
particular network conditions (such as low-bandwidth or high-latency conditions). These properties allow
