9.1 Upgrading AEC2.1 to Support Additional Four 4-Reader Boards
and Four 8-IO Boards
Using a LAN Converter, AEC2.1 system can be extended to support additional four 4-Reader
boards and four 8-IO boards. The converter UDS1100 can be linked to AEC2.1’s CPU LAN port
through an Ethernet network port to provide an additional multidrop communication channel.
This UDS 1100 can be mounted over the reader board (Refer to quick start guide for UDS
1100).
After mounting the device over the reader board, it needs to be connected to the CPU LAN
port of AEC2.1 through LAN (Ethernet) cable. There is a serial port RS485 from the device
which is connected to the main power and the reader board.
Figure below shows the wiring picture for the connections.

Alternatively UDS1100 can also be placed next to the reader board and connected (refer to
quick start guide for UDS 1100). The UDS 1100 is pre-configured with default IP address and
Subnet Mask. The user can connect it to the CPU, and access the extension panel by keying in
the default IP address in the web browser. (Refer to quick start guide for UDS 1100 for
details).
