PC Interface Connection

The following steps configure the hardware for interface to the PC:

1) Connect the DM2013H based smart battery to the EV2200 using wire

leads as in Table 7–1.

2) Connect the PC serial cable to the EV2200 and the PC COM port.

Table 7–1. DM2013H-to-EV2200 Connection

DM2013H Based Battery
