Product Details

The B&B Electronics BB5428 is a compact DB9 female-to-female null modem adapter designed for RS-232 serial communication. It allows two DTE (Data Terminal Equipment) devices to communicate directly by crossing the transmit and receive signal lines, eliminating the need for a null modem cable. This adapter is ideal for connecting laptops, PCs, and serial devices together for data transfer, programming, or diagnostics.

Key Features:

  • DB9 Female-to-Female null modem configuration for DTE-to-DTE serial connections
  • Crosses Tx/Rx lines and handshaking signals (RTS/CTS, DTR/DSR) for full null modem functionality
  • Compact inline form factor — no cable required
  • Compatible with RS-232 serial ports using standard DB9 (DE-9) connectors
  • Built to industrial-grade quality standards by B&B Electronics Manufacturing Company
  • Suitable for industrial automation, data acquisition, PLC programming, and embedded systems applications

The BB5428 is a dependable solution from B&B Electronics Manufacturing Company, a well-established manufacturer of industrial serial communication and connectivity products. Its straightforward plug-in design makes it easy to use in the field or on the bench without tools or configuration.

So far, ordering process is going good, easy. After placing my order, which as I previously stated, was easy and a fairly good process, I was worried. After about 2 weeks, my order had not arrived. I had attempted a few times to track my order using the provided information on my order confirmation email. However, my attempts fell short, as the tracking number listed was not the right one. To my dismay, I decided to just wait a couple more days. Then, when no package arrived, I decided to contact customer service. As I am a stay at home parent, with a 4 year old boy and a few nieces and nephews that I also help care for, it was at night that I sent my email. First thing in the morning I had received a reply. I was very pleased with the customer service!!!!! =) I explained my situation. The customer service representative responded that they would investigate as to what had happened and to retrieve the proper tracking information. Within a few hours, I received another email, with the right information!!! All in all, there were problems with the local FedEx delivery man...not with Autoplicity!! I had an extremely good experience I should say! Thank you very much for that!

Easy simple No floating banners to annoy me

Great shipping. Ordered multiple parts that said they were all available then a few days later got money back for one part. Claimed they were out of stock. Looked online again and said it was still available. Got money back right away though so all in all very satisfied!

A+

the right item at a very right price

I ordered a hitch off of this site for Christmas, I have never heard of it nor did I know how they were, but they are great! Got my package in I'd say 4 days, very fast and it was exactly what I wanted! Only down fall was they charged me 3 times and I was short 150$ for a few days. I got my money back and I would definitely order again.

Great prices and love the Amazon tie-in.
