The information in this page is updated in accordance with 07.10.2 firmware version.

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/li>
• 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 → Serial Utilities → Over IP page. Write the desired name for the new instance and select RS232 for the device name, and press the ADD button. In the newly opened tab, set the following configurations:

Enabled: ON

Under the configuration settings:

Select mode as server Port: 5555 (you can use any port; however, 5555 is used here as an example)

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.
