Driver

For Mac OS 9.x and lower, just run the USB-ATEN file, and follow the on-screen instructions as well. Once the installation is finished, plug in the GUC232A to any available USB port. To check if the device is successfully detected by the system, set your Mac desktop to Finder mode, then.

To install this package please do the following:

It’s not cheap at $29.99 (£22.99), but it works. I’ve not had any problems with any USB serial adapter (including USB consoles of Cisco devices) since I started using it. Highly recommended! Note from December 2015: You might try the driver from Aten. Go there, select Resources, then Software & Driver. The best USB to Serial drivers for macOS Drivers for CP2102 / CH340 / CH341 / PL2303 Devices. Program your Arduino, ESP8266 within a couple of minutes, control your Cisco, or download your GPS tracker, our drivers enable it.

- Save the downloadable package on an accessible location (such as your desktop).
- Unzip the file and enter the newly-created directory.
- Locate and double-click on the available setup file.
- Allow Windows to run the file (if necessary).
- Read EULA (End User License Agreement) and agree to proceed with the installation process.
- Follow the on-screen instructions.
- Close the wizard and perform a system reboot to allow changes to take effect.

About USB Network Adapter Drivers:

When connected, the operating system usually installs a generic driver that helps the computer to recognize the newly attached device.
However, proper software must be applied if you want to make use of all features that the network adapter has available. This task also allows computers to properly recognize all device characteristics such as manufacturer, chipset, technology, and others.
Updating the adapter's drivers and utilities version might improve overall performance and stability, increase transfer speeds, fix different compatibility problems and several network-related errors, as well as bring various other changes.
To install this release, simply get the package, extract it if necessary, run the setup, and follow the instructions displayed on-screen. When done, don't forget to perform a system restart and reconnect the network adapter to make sure that all changes take effect properly.
Without further ado, if you intend to apply this version, click the download button and install the package. Moreover, check with our website as often as possible so that you don't miss a single new release.

It is highly recommended to always use the most recent driver version available.
Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.

Status: Updated May 2021 - Big Sur 11.2.3 - Tested with ATEN (Prolific PL2303) and FTDI RS232R USB Dongles

Apple loves breaking old technologies...

The latest 'thing' to break with MacOS are some USB to RS-232 Serial Communications dongle drivers.

So for those of you who still have the need for RS-232 Communications and use Apple Macintosh computers here is the Big Sur low down.

RS-232 via USB Dongles

USB 1.0 was introduced in 1995 and is now in its forth generation with USB4, which means USB is now over 25 years old. Nowaday's pretty much every desktop, notebook and server computer have USB ports and RS-232 ports are only on either specialist or older devices.

To allow newer USB equiped computers to talk to RS-232 based devices you need a USB to RS-232 dongle. These are sold under various brands but most are based on either:

  • Prolific PL2303 Chips - used by ATEN USB/RS-232 dongle
  • FTDI Chips - 'Future Technology Devices International' based dongles use community developed drivers

The USB dongle requires a device driver, which with MacOS Big Sur need to be 'notorised' (signed) to work.

MacOS Big Sur has FTDI based devices supported by in-built Apple device driver. Currently there is no Big Sur device driver available for the Prolific based USB Dongles.

NOTE #1 - As per feedback (below) from 'Brandon Applegate' and 'David Rankin' below I retested my Prolific PL2303 with Big Sur 11.2.3 and am happy to report that the Prolific PL2303 Dongle now works again. It reports as: '/dev/tty.usbserial-1430' on my Intel MacBook Pro.

To see what type of Dongle you have look at the 'About This Mac' report under USB:

If you have a FTDI device then you should be able to find the RS-232 devices by opening the Terminal and doing: 'ls /dev/ttdy.usb*'

On my Mac the device is: '/dev/tty.usbserial-A50285BI'

In MacOS Catalina and earlier the Prolific based devices where available as: '/dev/tty.UC-232AC'.

Retesting with Big Sur 11.2.3 the Prolific Dongle reports as: '/dev/tty.usbserial-1430'

Using FTDI Dongle

If you have a FTDI based USB dongle then you can start a serial communications session using the in-built 'screen' application via a Terminal window: 'screen <DEV> <SPEED>'.

Aten Usb Driver Mac Downloads

As a example, for serial communications session at 38400 Baud (on my machines, Terminal window): 'screen /dev/tty.usbserial-A50285BI 38400'.

NOTE: The exact device name may vary from one machine to another.

Using Prolific Dongle

NOTE #2: Retesting with Big Sur 11.2.3 the Prolific Dongle now works with built in Apple USB driver. So if using Prolific Dongle just make sure you have updated to lastest MacOS version.

Otherwise the below will apply...

If you have a Prolific Dongle then you have a number of options:

  1. Get a FTDI Dongle or
  2. Get a serial communications program that directly supports the Prolific Dongle. One such program is: 'Serial 2' by Decisive Tactics. There might be others, but I have tested Serial 2 with an ATEN Prolific based dongle and found it to work
  3. Wait for a device driver to be available ... but now wait is over

NOTE #3: As per NOTE #1, the Prolific Dongle now works via the Apple provided driver, so there is no need to install any new Prolific drivers. My testing was with Intel MacBook Pro and Big Sur 11.2.3 and David Rankin reports that is also works with MacBook Pro M1. So good news for all.

Which option you choose is likely based on how comfortable you are with the MacOS Terminal and screen programs. When using the 'screen' application remember that the keystrokes 'Ctl-a Ctl-' should get you to the quit prompt and 'Ctl-a ?' for help.

Plugs and Cables - I have dongle but no communications

Having got a dongle then you need to ensure you have the right physical plug and the right cabling.

Most USB/RS-232 dongles have male DB-9 (or officially DE9) connector, as does most computer equipment. In the language of RS-232 a computer or end device (Cisco Router for instance) behave as 'Data Terminal Equipment' or DTE. As RS-232 come from history of remote communications, the DTE device is expected to connect to a 'Data Communications Equipment' (DCE) device (a modem).

The standard cabling for RS-232 is therefore expecting DTE to connect to DCE, which uses specific wiring for the data and control signalling. In most cases where you are using you Macintosh you will have a DTE to DTE connection (ie Mac to Router or Mac to other Computer). So in this case you need what is called a 'NULL Modem Cable'. This is a cable which has been wired to accommodate that there is no modem (or DCE device) in the connection chain.

A typical situation is that you will need to DB-9 (DE9) Female to DB-9 (DE9) Female NULL Modem cable to allow serial communications to work correctly.

Another possible situation with much older equipment is that rather then having DB-9 plugs your devices have the original and much larger DB-25 plugs. Old modems (a DCE device) typically had DB-25 Female connectors, so no need for NULL modem, but you will need a DB-9 to DB-25 plug adaptor.

So in additional NULL modem cable your RS-232 toolkit might need physical plug adaptors as well.

Other possibilities include:

  • RJ11 - (Registered Jack) which are used on Cisco Routers. The router is typically provided with RJ11 to DB-9 Female cable for connecting to DTE device (ie computer). I have also seen these on Juniper routers, Areca & Promise disk arrays, as with Cisco these are all provided with their own cable, typically wired for connection to DTE
  • Mini DIN-9 - used on old Macintosh Computers and 'Apple compatible' modems. The computers are wired as DTE and modems as DCE.

So get your cable and plug ready and when all else fails read the manual and get a break out box and volt meter.

Welcome to RS-232. Don't forget that a UART is a 'Universal Asynchronous Receiver-Transmitter', this is essential serial comms knowledge ;-) .
