1. Source 2. Cabling
The maximum number of devices (N) that can be connected to the source is determined by checking if the source
current (IS) required to drive the connected devices is less than the maximum drive current the source can
provide, and verifying that the load voltage (VL) the connected devices see is greater than the minimum required
voltage.

IEEE 1588 Support

RSG2488 supports various IEEE 1588 time synchronization capabilities and provides synchronization in 1-step
and 2-step modes. However, of the 28 ports available, ports 2/4, 4/4, 6/4 and 7/2 only support 1-step mode and
select clock types. All other ports support both modes and all clock types.
