COM3 DB9 Connector

The COM3 Port uses a standard DB9 female connector. The suggested connections to the computer
are shown in Figure 4 to Figure 6.
When connecting data terminal equipment (DTE) together (such as a COM1 port to PC serial port), a
null-modem cable must be used. One possible configuration for a null-modem cable is shown in
Figure 4.
Figure 4: Null Modem Cable Configuration
When connecting data terminal equipment to data communication equipment (DCE) (such as the
D6600/D6100IPv6/D6100i COM port to a modem), a modem cable should be used (such as a straight-
through cable shown in Figure 5).

Each pin of the modem cable is defined in Figure 6.
