Altec PC410 (BGA Rework) to communicate with PC

[pronester]

hello guys,

I am trying to control my homemade BGA rework with RS485 (USB) using a desktop PC, but a dialog box keep pop up saying communication error - cant establish connection between the BGA machine and the PC (refer pic).

Some information:
- using windows desktop PC
- the software - PSoft Rework v 2.3.1
- the RS485 and the PC410 are properly connected i.e wired to the right pins
- trying other IR6000 software but require a password for installation

Appreciate your suggestion on how to rectify the problem.

Thanks.
