Console Port Connector Pinouts for a CTP151 Device
The console port (labeled CON) is an RS-232 serial interface that uses an RJ-45 connector to connect to
a console management device. The default baud rate for the console port is 9600 baud.
Table 12 on page 29 provides the pinout information for the RJ-45 console connector. An RJ-45 cable
and RJ-45 to DB-9 adapter (p/n 720-014126) are supplied with the CTP151 device.
NOTE: If your laptop or PC does not have a DB-9 male connector pin, you must use the Mini-USB
console port on the front panel of the CTP151 to connect your laptop or PC directly to the
CTP151 device. If your PC or laptop has a DB-9 male connector pin, you can use a combination
of the RJ-45 cable and RJ-45 to DB-9 adapter supplied with the device to connect your PC to
the CTP151 device.
