Try out whith your multimeters conductivety test if all the contacts have a good conection and that they are conected right.

Resistor leads fit in the Female conectors prety well and those small crocodile clips are good for males.

Test it pin by pin!

Some devices require "null-modem" cables, where RXD and TXD pins are swaped (just like crossed ethernet cable), try that.
