RJ45 Ports
The IR1101 supports one ISOLATED RS232 port which conforms to EIA-561 standard.
The RJ45 pinouts are shown in Figure 12 .
Figure 13: S0 Characteristics
The RS232 port is a DTE and its pin out is shown in Table 10: S0 Details, on page 18.

Ethernet and Optical SFP Modules
The IR1101 Ethernet and Optical SFP modules provide connections to other devices. These field-replaceable
transceiver modules provide the uplink interfaces. The Ethernet and Optical modules can be either copper or
optical. Details are in the two tables listed below.
The Local connectors (LCs) provide the fiber-optic connection. RJ-45 connectors allow copper connections.
You can use any combination of the supported SFP modules listed in the table that follows.
Note: The IR1101 is designed to operate in the Industrial temperature range (-40C to +85C internal component
temperature range) and therefore cannot support commercial rated SFPs.
