Local RS232 Serial Port Connector
A DB-9 connector (J3) with a male housing and female pins supporting a local RS-232 port with a
subset of handshake signals is provided for local terminal access. This connector provides an isolated
RS-232 communication port for notebook computers and PCs.
The local port pin assignments should take the assignment as a Data Circuit-terminating Equipment
(DCE). This assignment is shown in the following table.

* These signals are not necessary for supporting a local port connection.
LAN Connection (Ethernet)
A standard integrated RJ-45 receptacle (P6) is provided on the QS841A for connecting to an
appropriate 10/100 Base-T LAN. P6 is shielded with the shield being tied to chassis. This connector is
accessible when the controller is inserted in the shelf. The signals and pin assignments for this
interface follow industry standard and are shown in the following table:
