The difference is in switch board which is inserted in slot 0

Switch board difference

Differences：

1. V2 switch board support core board.

2. There are USB and RESET buttons in V2 switch board.

3. The slot LED lights in the V2 are red and green, and gateway module are distinguished according to the different colors.

Whether switch board support the core board

Not support

Support

Note: If there is no core board in switch board, then it supports functions and modules which are supported by GW2120 V1.

GWM1202 V2 core board system is divided into two types:

1. Wireless gateway

2. Analog gateway

The core board can be installed one of the two systems before leaving factory. The core board mainly works as the master of GWM420G/W/L and GWM820S/O.

Modules supported

1. Wireless module GWM400G/W    GWM401G/W/L

2. Analog module GWM800S/O     GWM801S/O

3. E1/T1 digital module ET200X

1. Wireless module：GWM400G/W   GWM420G/W/L（need core board）    GWM401G/W/L

2. Analog module：GWM800S/O    GWM820S/O（need core board）    GWM801S/O

3. E1/T1 digital module：ET200X

ET200X

Any 11 and less than 11 of modules above can be mixed in one chassis

1. With GWM420G/W/L or GWM820S/O（The chassis need to be inserted one core board). The chassis can be inserted one of the below:

GWM401G/W/L

GWM801S/O

GWM400G/W

GWM800S/O

ET200X

Note: GWM420G/W/L and GWM820S/O can’t be inserted in one chassis in the same time. Because the core board only can be installed one system (wireless system or analog system). If GWM420G/W/L and GWM820S/O are inserted in one chassis in the same time, only the board whose core board inserted can be detected.
