Data Connections
Table 3.2 lists the electrical connections for the two serial ports on the Model 1133A. The section
below also describes the Ethernet connector.
3.6.1
Serial Interface Connections
The 1133A has three standard communication ports: two RJ-11 serial and one RJ-45 Ethernet. The
two RJ-11 serial interface connectors may be optionally configured for RS-232C, RS-485, or V.34bis
Modem. Choose the serial port option at the time of order. Standard serial cable connectors are
(normally) a DB-9F at the computer and RJ-11M at the 1133A. A standard phone cord and RJ-11
to DB-9F adapter work well connecting the 1133A to a computer. Modem connections may be a
standard phone cable. Pin connections are shown below.

Ethernet Interface Connections
One IEEE 10base-T interface connector (see Figure 3.12) allows connection of the 1133A directly
to a network (Conforms to the IEEE 802.3i) using one RJ-45 connector. To configure the IEEE
10base-T Interface, see Configure Ports
