Pin # Signal Name

232DCD (RS-232 Data Carrier Detect)

2 232RXD (RS-232 Receive )

3 232TXD (RS-232 Transmit)

4 232DTR (RS-232 Data Terminal Ready)

Ground (Current Limited Ground)

6 232DSR (RS-232 Data Set Ready)

7 232RTS (RS-232 Request To Send)

8 232CTS (RS-232 Clear To Send)

9 NC (No Connect)

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

Figure 11:

Configuration Menu (part 2)

and 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.

8 Power And Sense Connector

(Skip if NE843C/NE843E/NE843G/NE843P pre-wired in factory)

Basic power and sense to connector J9 must be made in order for the controllers to function. The

pin assignments for J9 are listed below.
