HBS57H driver board

High everybody,I’ve got a problem with HBS57H driver board , made by maybe ECON Technology in China.I would like to communicate with it so I’ve hooked up with PC with a DB9 – RJ11 cable.I have already tried with Longs Motor ProTune program, and I’ve monitored the COM1 port withSerial Port Monitor by ELTIMA.  I was seeing the communication on he COM1 port, but at the endthe status of the driver board was not connected and the port was closed.I’have tried out with ECON Chinese program, but than I’ve not seeing anything on COM1 port, and I was not able to communicate with the driver modul.I would like to know the pinout of the DB9-RJ11 cable, because I’m not sure of it.And maybe something information and solution for HBS57H driver modul.I've not hooked up the motor for the driver board, because at the moment I just want to communicate the driver board and read out from it the settings.Thank you
