S2GW hardware preparation

The S2 gateway (P/N S2GW) with its power supply is shown below. The power supply delivers 5.1V/2.5A and is equipped with micro-USB plug.

The S2GW label is shown below. It contains the unit MAC address which may be used as an identifier in B3. It also contains HW:B for devices based on Banana Pi SBC. The units using Raspberry Pi has no HW parameter.

1. It is necessary to open the gateway enclosure to connect power supply. Pull the upper cover of the enclosure to open it.

2. There is SBC inside with a S2GW HAT PCB installed on GPIO connector. The S2GW HAT PCB has a micro-USB connector used for 5.1V power supply and an S2 PC node serial cable used for communication with an S2 PC node or S3 node.

1. Connect the power supply to the micro-USB connector on the S2GW HAT PCB.

2. Put the top of the enclosure back in place. The power supply cable and S2 serial cables shall be led in parallel through a slot between the bottom and upper part of the enclosure as shown on the picture below.

3. Put the S2GW and its S2 PC node or S3 node into a DBU002/2 holder as shown below.

4. Connect S2 PC node serial cable into S2 PC node or S3 node serial socket.

5. Connect Ethernet cable into S2GW Ethernet socket.

6. Connect 9V power supply into S2 PC node or S3 node power input.
