B.4 SI-10BT

The SI-10BT is a physical twisted pair (10BaseT) interface to the 68EN360 Controller

chip. It connects one of the range of PEP CPU boards to an unshielded 100ohm

twisted-pair cable via an RJ45 telephone jack.

The SI-10BT has two LEDs fitted: a red LED indicates collision detection and a yellow

LED for data.
