MX301 Management Cable Specifications and Pinouts

MX301 Cable Specifications for Console and Management Connections

Table 1 provides the specifications of the cables that connect the router to a management device.

Table 1: Specifications of the Cables for Console and Management Connections
Port on the Router	Cable Specification	Maximum Length	Device Receptacle
Console (CON) port	RS-232 (EIA-232) serial cable	2.13 meters	RJ-45
Management (MGMT) port	Category 5 cable or equivalent suitable for 1000 BASE-T operation	100 meters	RJ-45

Note:

We no longer include the RJ-45 console cable with the DB-9 adapter as part of the device package. If the console cable and adapter are not included in your device package, or if you need a different type of adapter, you can order the following separately:

RJ-45 to DB-9 adapter (JNP-CBL-RJ45-DB9)
RJ-45 to USB-A adapter (JNP-CBL-RJ45-USBA)
RJ-45 to USB-C adapter (JNP-CBL-RJ45-USBC)

If you want to use RJ-45 to USB-A or RJ-45 to USB-C adapter you must have X64 (64-Bit) Virtual COM port (VCP) driver installed on your PC. See, https://ftdichip.com/drivers/vcp-drivers/ to download the driver.

5	TRP3–	Transmit/receive data pair 3
6	TRP2–	Transmit/receive data pair 2
7	TRP4+	Transmit/receive data pair 4
8	TRP4–	Transmit/receive data pair 4

MX301 Console Port Connector Pinouts

The console port (labeled CON) is an RS-232 serial interface. You must use an RJ-45 connector to connect to a console management device. The default baud rate for the console port is 9600 baud.

Table 3 provides the pinout information for the RJ-45 console port connector.

Note:

If your laptop or PC does not have a DB-9 plug connector pin and you want to connect your laptop or PC directly to the router, use a combination of the RJ-45 cable and RJ-45 to DB-9 adapter and a USB to DB-9 plug adapter. You must provide the USB to DB-9 plug adapter.
