Bluetooth debugging is so hot, why are the big guys still insisting on using the console line?

Good evening! My friends.

There's one in my networker's backpack. Essential Tools ——Console The line.

Even though it looks like an ordinary wire, It's with you every day.  

Today we're going to meet. Let's really talk about the various types and uses of this wire.

01 Console Line Arena: The Rich vs. the Poor  

1. The cable party:

wired Console, looks ordinary but reliable.

Modular : Flexible for old equipment

one head USB to DB9, a DB9 to RJ45, combined to kill the oldmodel of equipment.

The most realistic scene I've ever seen: one in a lab. In 2005, the Console port was actually DB9 direct connection, thanks to the package with a split line, or on the spot.

shortcoming : The interface nut often does not match . It needs to be adjusted repeatedly when inserting and removing .

All-in-one : Simple and direct mainstream choice

A line goes all over the world, The RJ45 interface adapts to most modern devices.

I recommend buying it. The length of more than 3 meters, triedto use 1 meter short line squatting in front of the cabinet debugging, the waist is fast acid into C Done. Long lines can be used by you sitting in a chair, The posture is very comfortable.  

Special Interface Special Lines
I've met you. Miniusb, Micro-USB or even a console port with direct serial connection?

Once I commissioned a niche brand device and looked around for half a while before I knew I needed to use it USB to TTL line . From now on , get into the habit of checking the interfaceexplanation of the device before seeing the customer .

2. The Wireless Party:

Bluetooth Console : Good helper for flexible debugging

The palm-sized adapter can connect the device with a short wire.

Try connecting equipment through the glass at the door of the machine room, avoiding the dust and noise of the site, and knocking on orders while drinking coffee, and passing colleagues think I'm working easily.

remind : Do not use in environments where wireless signals arecomplex, which may be stalled, and must still switch back to wired mode to stabilize at critical moments.

Wi-Fi Console : Alternative for Remote Scenes

Transmission of data over a network can theoretically be managed across network segments, but the latency is obvious When you hit a command, you wait half a second for feedback, like inSlowly type a chat Oh, hurry. Use your sex sparingly.

02 How to debug the device

1. Pre-Preparation: Finding the Right Tools and Interfaces

Tool list : computer , Console线、 SecureCRT （ If you don't, call me. I'll send you a message. ）  

Wiring operation: Plug the USB end into the computer , and plug the RJ45 end into the device 's Console port （ usually marked " CONSOLE " or " AUX " ） . View Port : Right click " Device Manager " on your computer → "Port", note the COM port number （e.g。COM4） ，This is the "channel number" of the connected device.

2. Connectivity and Basic Configuration: Step by Step

open SecureCRT , select the " Serial " protocol , fill in the portjust found COM4 , baud rate select 9600 （ default parameters of the device ） , click connect .

03 Details determine efficiency.

Prepare two lines to prevent accidents

Wired and Wireless One console cable each, like a double backup. When I tried to cut at three o'clock in the morning, the Console line suddenly had bad contact, thanks to the backup line to save the scene, otherwise I would have to write a fault reportat dawn.

Check your equipment before you leave

The Bluetooth model is fully charged. The wired plug-in computer confirms port identification. Don't go to the site to find the wire There's a problem. —— What's more troublesome than forgetting to bring a tool is that the tool can't be used.

Choosing a long line is more practical

Priority Selection About 5 meters of wired wire. When the cabinet is in a corner or the equipment installation is deep, the longwire can allow you to operate in the appropriate position. Don't have to crowd around the device to suffer.
