Au J1939 to J1939 Gateway

There are two types of Au SAE J1939 to J1939 gateway available. The first product (part # GW2-1939-1939-001) is able to convert SAE J1939 engine data from source address 1 to source address 0. The second product (part # GW2-1939-1939-002) is able to convert SAE J1939 CAN baud rate. Both products share same hardware but different firmware.

When connecting the GW2-1939-1939-002 to the CAN network, make sure pin-5 and pin-6 are wired for the source network, which is designated as CAN1. You can use use the command AT CAN1BRS=xx to configure the GW2 CAN1 baud rate to match the source CAN network baud rate.
Pin-1 and pin-2 are designated for the target network, CAN2. You can use AT CAN2BRS=xx to set the GW2 CAN2 baud rate to match the target CAN network.

For example:

Use AT CAN1BRS=00 to set GW2 CAN1 baud rate to 250K BPS.
use AT CAN2BRS=03 to set GW2 CAN2 baud rate to 500K BPS.

With this setup, the GW2 will convert CAN baud rate from 250K to 500K BPS.
