Introduction

This article describes how to connect to a console of another device (e.g., a Cisco router, Fortigate firewall, etc.)

Prerequisites

You will need:

  • A router/gateway with USB or RS232 Serial
  • An RS232 (male) - RJ45 cable (to connect to a Cisco AUX port):
  • Or a USB type Mini - USB type A cable (to connect to a USB type mini console port):

Configuration

There are multiple ways to connect to a console port, which are described in the sections below:

RS232 - RJ45

RS232 can be configured from the Services → RS232/RS485 → RS232 Configuration page. The following RS232 configuration should be used:

  • Enable RS232.
  • Select baud rate (9600).
  • Select Serial type (Over IP).
  • Select Protocol (TCP).
  • Leave mode as Server.
  • Type in port (15026)
  • Save configuration

USB

Using Mini USB – USB type A configuration. Configured from the WebUI, Services → USB Tools → USB to Serial page:

Firstly, we'll need to add a new USB to Serial instance:

  • Type name.
  • Press Add.


Then, we'll need to configure this instance:

  • Enable
  • Name should be already written
  • Select device ID
  • Select baud rate
  • Choose two Stop bits
  • Select Serial type (Over IP)
  • Choose TCP protocol
  • Leave mode as Server
  • Type in port (43223)
  • Save configuration

PuTTY configuration

The console can be accessed by using software such as PuTTY (can be downloaded from here.

The PuTTY configuration should look like this:

  • Type in routers/gateways IP
  • Select port you've configured in RS232/USB to Serial.
  • Select RAW connection type

Then you should successfully connect to Cisco device:


If you do encounter any issues with PuTTY, you can try connecting from Teltonika's device directly to Cisco's:

  • Connect to router's/gateway's CLI
  • Type in this command "microcom -s 9600 /dev/rs232"

This way you'd know if Teltonika's device is even able to see whats on the other side of RS232.
