5.2. CON1 (LAN Connector)
CON1 is a 10BASE-T/100BASE-TX LAN interface. It can be connected to an Ethernet cable of category 5
or higher. Normally, it is connected to the hub via a straight cable. Using a cross-cable, you can connect
it directly to your PC.
It also supports Power over Ethernet (IEEE802.3af) thus allowing the supply of power over Ethernet cable
using a PoE power feeder that is capable of supplying power using LAN connector’s (4),(5) pin pair and
(7),(8) pin pair.
Note 1: When using Power over Ethernet, use a cable with all wires installed.
Note 2: When a LAN connector is reconnected while Power over Ethernet is used, supply of power may be
delayed for a few seconds at the HUB side due to the operational confirmation of a power
receiving device. This is not an operational problem.

5.3. CON2/CON3 (Serial Interface 1)
CON2 and CON3 is an asynchronous serial interface. It is connected to UART1, CPU (EP9307). CON2
and CON3 differ in shape and pin assignment, but they have common serial signals.
