We can offer two kinds of serial cables , if needed, please choose to buy:
Male to Female direct serial cable: connect serial server and the computer directly to debugging and
Testing.
Male to Male and Cross Pin2 and Pin3 serial cable: used to connect RS232 serial port server and
general user equipment.

There are three jumpers and one Welding hole:
UPD: Update jumper, connect it and then power on the module to make module into update mode.
CFG: configuration jumper, when use RS232 for configuration, connect it to configuration mode ,and
leave it free to go work mode.
Notice: CFG is needed only When config via RS232, when config via RJ45, it is no use .
