Note: an RS-232 to USB adapter (dongle) may be used to connect the RS-232 port to the USB port
of a PC. Adapters may require a specific manually set baud rate to operate properly. See
Table 32 Communication Ports Configuration
Note: before connecting the USB or RS-232 port to your PC, be sure that the power system and
its output are properly grounded. Discharge Ground (DG) bus must be bonded (connected) to
earth ground.
CAUTION: damage to the controller may occur if the USB or RS-232 port is connected to a PC
when Discharge Ground (DG) bus is not bonded (connected) to earth ground.
NE843C/NE843E And NE843G Controllers Only
The connections described in Steps 8 and 9 are automatically performed internally through the
backplane connection for NE843A/CP843A/EP843D Slot-Controllers. Although the Infinity NE-M,
NE-D, NE-S and P2 systems have the NE843C, NE843E, and NE843P pre-wired in the factory, the
connections are valid.
