sunlink Options


Clock source 

Select either the on-board clock or an external clock for use when using sunlink. To use the external clock option, the transmit, receive, and clock data lines must be physically loopbacked.

Internal Loopback 

Enables or disables internal loopback tests. Internal Loopback is only needed when the Loopback setting is not port-to-port, and the clock source is on-board. 


Specifies the loopback type: simple single external port loopback, multiple external port loopback, and port-to-port external loopback.
