Baud rate and Latency Table
The following table lists the optimized MTU and IFG and resulting latency for the SEL 2505 device, one of
the faster devices available so serves as an ideal starting point when introducing new devices. It is
recommended that initial testing is carried out with one step size higher (8) on MTU.
