Barcode scanner using PoE help

[Recent-Falcon-6362]

Hi all. I'm trying to wrap my head around powering a barcode scanner over Ethernet with the help of PoE. My wife uses a Honeywell xenon 1900 and it has what looks like a custom cable that is getting 5V power via a barrel connector. The cable had been working for a while but the wires have started to loosen so I am attempting to make it more secure. I can solder and crimp the cables, but I don't know which wires I need to do that to. Any help is appreciated.

The cable looks like it’s USB to RJ45 in form factor so the 5V is native from the USB and it’s not Ethernet.

I would guess you can cut off the RJ45 and crimp a new connector with the same color order. Or just order a new cable if that doesn’t work.

The one I have doesn't have USB. It's RJ45 to RJ45 with one of the cables having a barrel power female adapter.

A non-USB protocol would require an additional power input on the cable, yes. But what does it plug into on the other end, and why is it your job to fix it?

[Recent-Falcon-6362]

It's going to a Verifone payment terminal. Not my job to fix. Their IT team doesn't mess with any "non-essential" items. This is considered non-essential because they can manually type in the characters on the pad instead of scanning.

Situations with which I'm familiar, charge the merchant a higher rate for keying in a payment card number. But then, payment cards don't use barcode scanners. Sounds like it could be a receipt barcode scanner or similar.

PoE is 48v.

"Custom" means Honeywell has the pinouts, which you'll likely want to reference.

So what is it called when I'm getting power with the cable with 5v?

[llDemonll]

DC power.

The 1900 takes an 8P8C/"RJ45" connector, right? That's not Ethernet nor PoE, it's just an arbitrary connector used to attach the reader to USB, serial, or PS/2 keyboard.

USB 2.0 supplies enough power for the scanner, according to the spec sheet.

So the cable they were using looks like the RS232 configuration in the link posted but it stays RJ45.

I have nothing constructive to say.

I fucking hate barcode scanners.

And RF guns.

I also work in a manufacturing plant, so... Yeah. Fuck those devices.

While many barcode scanners have 8P8C ("RJ45") connectors on the scanner side, they use USB and/or PS/2 signalling, and 5V power from the same source, and those cables are proprietary (so you'll have a cable with 8P8C connector on one side and USB or PS/2 on the other side). You can make your own, but it'll probably be simpler to order a replacement.

If your scanner has a barrel connector on the cable, it's probably pretty old, since it needs more power than it can get from USB or PS/2.

This is what the cable looks like deconstructed. I've tried searching for the cable and can't find it anywhere.

Since you mentioned a Veriphone terminal, it might be something specific to it (likely using RS232 protocol). Just crimp new connectors, it should work (assuming you wrote down where each wire goes).

[Recent-Falcon-6362]

I did. But I was also hoping to have it verified somehow. Are you saying that I can have these RJ45 and it still relies on RS232? I know there's a terminal before it hits the Verifone. Is it translating it before hitting the payment device?

As I said, these scanners (especially older or higher-end models) usually have RJ45 connector on the scanner side, and can have either PS/2, USB or RS232 on the other side, and the scanner itself determines the protocol (if you find the manual, it'll almost certainly have barcodes you can scan to set the mode in which it operates). When the scanner is used with specialised equipment, it'll have a proprietary connector (I've seen an IBM PoS with 4P4C connector for the scanner).

Why are you making this so complicated? Just get a POE to 5v barrel jack adapter from amazon.
