Baud rate and Latency Table
The following table is arranged by serial baud rate followed by Aprisa SR+ channel size and modulation. It
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.
