2.4Connecting the BDI2000 to Host 2.4.1 Serial line communication

Serial line communication is only used for the initial conﬁguration of the bdiGDB system.

The host is connected to the BDI through the serial interface (COM1...COM4). The communication cable (included) between BDI and Host is a serial cable. There is the same connector pinout for the BDI and for the Host side (Refer to Figure below).
