Selection Jumper on I/O expansion v5.0
Account cancelled 2011-10-23 05:47:02 3567 Views1 Replies Dear all,
i have bought a DFRurduino I/o expansion v5.0 shield.
I want to use it for a Modbus communication over Rs485.
I don't know how to selection jumper must be placed for select RS485 and not APC.
I have tried to see schematics but i'm not able to find a solution.
Can you help me?
Thank you!!

With the IO Expansion shield facing you and the Xbee module closest to you, on the top left side there is a set of 3 jumpers on one side it says "APC" on the other RS-485, just move all three jumper from left to right. That will enable the RS-485
If you need more help just let me know :)
Happy hacking! Hector
