C2G 06691 Modular Adapter
  • Verified Owner
  • Owned For: 1 week to 1 month

4 out of 5 eggs Odd but Very Very Useful 12/23/2010

This review is from: C2G 06691 Modular Adapter

Pros: I can attest to the fact that putting RS232 Comm on a Cat 5e cable is the way to go. Much easy to work with and Cables are easy to make.

As many of you who would buy this would know you typically have to customize plugs for various RS232 configurations. I bought these so I could set up XON-XOFF which required shunting some of the pins (DB9 #1-4-6, 7-8). I stripped and twisted the tiny wires then put on electrical tape, then inserted them. Works good, and fits, taps would be too big to use. I used DB9 2,3,5 dead ended the others (that connect to the RJ45 pins) and put electrical tape on them to stop them from possible contact (very little tape). Also, I decided to make them a pair, so had to NULL (cross) 2,3 on one of the connectors.
This is awesome, just clip these on and connect a standard Lan Cable and they work good and provide a clean signal. I am really happy to get this done so neatly.

Cons: It says 10 pin RJ45 and it is 10 pin! Perhaps I am ignorant but I only have 8 pin RJ45s. No fret, they work just their pin 1 and 10 do not have contact with a standard 8 pin RJ45.
The screw things are really cheap.
No drawing to tell me what color goes to what pin on the RJ45 so had to ohm them out.
Would also be nice to include info on what the recommended connections should be from DB to RJ.

Other Thoughts: If you are looking at this for the same reasons I did here is some helpful info.
I went to this site and got a recommended connection for DB to RJ serial. Scroll down the page a bit to find it. Big answer for me is yes, run TXD and RXD on a pair.

Pin out for RJ45 was as follows for the one I got.
RJ45-wire color --- Standard 8 wire LAN cable (568A) wire color.
1-purple-not connected
2-blue-orange stripe
3-orange-orange
4-black-green stripe
5-red-blue
6-green-blue strip
7-yellow-green
8-brown-brown stripe
9-gray-brown
10-white-not connected

Hope this helps

CABLES UNLIMITED Model USB-2920 USB 2.0 to Serial DB9 Adapter
  • Verified Owner
  • Owned For: 1 week to 1 month

4 out of 5 eggs Hardware Flexible 12/23/2010

This review is from: CABLES UNLIMITED Model USB-2920 USB 2.0 to Serial DB9 Adapter

Pros: I have a couple USB to serial adapters this one gives you more control options in your comm port properties than others do (i.e. Block Size). I am running this from XP machines so can't speak for Win7.
Those of you that connect to OLD machines and especially who work in industry will appreciate this.

Cons: Well the Screws are wrong for most connections but nothing you can't mostly fix with a couple spare nuts.
The light is bright (someone else mentioned this) I covered it with electrical tape.

Other Thoughts: I bought this to connect to a 1994 CNC machine running Burny 2.8 Controls that downloads from an old 486 Dos machine. Want to get this on an XP machine but most everything serial is just too blazing fast for this old machine hence I need block control... and have to run it at 1200baud (note that is 1.2k).

ASUS VH236H Black 23
  • Verified Owner
  • Owned For: 1 month to 1 year

Pros: I am trying to sneak around the fact that Newegg doesn't allow reviews on Open B items.
I took the chance, and it is perfect... no dead pixels... nothing wrong. In fact, it looks better than the identical old one I had (I wanted the second for a second monitor as I like the first one) so I figured O Box was worth the risk as it would be my primary monitor.

Cons: It looked better than the identical older one... I mean the blue background is bluer, colors brighter. So I wonder about how well these perform over time. I would have never known if I hadn't got this one.

Other Thoughts: I can't imagine going to smaller monitor, I use this computer for apps not entertainment but I constantly have multiple things open and need two monitors. This can't be beat for the price.

Nobody tell Newegg that I reviewed a xob nepo item
