3.2. I/O Extender

The I/O Extender serves to provide additional Interfaces to the Nano Module for the customer to interact
with. These include Wiegand, RS485/422, CAN and Relais. An LCD Screen is also available to assist with
application bring-up.
The I/O Extender can be connected to the TWN4 MultiTech Nano Module via the Expansion slot on the
Development Board. Please see the I/O Extender Technical Handbook for more information.
Instructions to Enable
"COM2-LED & Speaker" DIP Switch bit 2:
There is a bank of 4 LEDs available next to the "LED Connect" DIP
Switch. Use the DIP Switch to enable individual LEDs. These LEDs
are driven by Nano Module GPIO ports 0-3.
There are 5 LEDs next to the COM ports. These include "Nano Module
Power-ON", and RX/TX traffic indicators for both COM 1 and 2 ports. To
enable these LEDs, set "COM2-LED & Speaker" DIP Switch bit 1 to ON.
For COM2 port, see also entry directly below.
COM2 port is functional without any extra board changes. To enable
traffic LEDs on COM2 port, set "COM2-LED & Speaker" DIP Switch bits
3 and 4 to ON. See Table B.4 for details.
No additional steps needed to activate. Simply insert card.
Can be used as a general-purpose port if the main interface to Host is
USB (Micro or DF11). Set "COM1 & Power-ON" DIP Switch bits:
1=ON, 2=OFF, 3=ON, 4=OFF.
Also disable RS232 transceiver by floating Pin 8 (MGND) of DF11 port.
Can be used as a general-purpose port if the main interface to Host is
USB (Micro or DF11). Set "COM1 & Power-ON" DIP Switch bits:
1=ON, 2=ON, 3=ON, 4=ON.
The same connector can be used for both USB and RS232.
See Table B.1 for instructions.
