DB-9 pin assignments

In conjunction with the pin assignments provided for the 3-pin receptacle on the rear panel of the HP e1200-320 4Gb Interface Card, following are the corresponding pin out assignments for a DB-9 serial connector used to connect the other end of the serial cable to a terminal, or a computer running terminal emulation software.

The pin assignments given in Figure 78 for the DB-9 serial connection are in reference to the serial connector at the end of the cable. Use an RS-232 null modem cable to connect the HP e1200-320 4Gb Interface Card to the host system.

NOTE: To connect the Interface interface card to a host system, use the RS-232 Serial3-Pin-to-DB-9 cable included in the shipping container for this product.
