You can connect the IN to your other OUT midi device and the OUT to your other IN midi device.

What is your programmer ?
Do you have his pinout ?

Yes, but the connector is a 6 pin.
pin 3 to pin 6 are used for data.
pin 2 is used for the power.
pin 1 is reset/Vpp and is not used in LVP mode.
Serial connector do not provide the power.
You must connect the USB when you program the chip to provide the power.
