What clock pins do I need to connect when testing my synchronous serial card with a loop back?

For Sealevel synchronous serial products, after connecting the Transmit (TX) and Receive (RX) pins, you will need to connect the Clock Output pin (TSET) to the Clock Input pin (RXC). In most cases, the Clock Output pin (TSET) should be used as the board’s output clock. Transmit Clock (TXC) is an input and should not be used.
