Protect critical serial and network connections with the Black Box Surge Protector, engineered specifically for RS-232 and Token Ring interfaces. This 8-wire surge protector delivers ultra-low shunt capacitance to preserve signal integrity, even on high-speed data lines. Featuring state-of-the-art avalanche diode technology, it clamps transient surges quickly to safeguard both equipment and data. The spring-loaded design ensures wires stay securely connected, preventing loosening under vibration or movement. Whether in industrial environments, research labs, or office networks, this surge protector helps maintain reliable communication by shielding sensitive lines from spikes and electrical noise.

  • Comprehensive protection for RS-232 and Token Ring networks, shielding sensitive serial lines from damaging voltage surges.
  • Low shunt capacitance minimizes signal loss, preserving data integrity and transmission speed across 8-wire configurations.
  • State-of-the-art avalanche diode technology provides fast, reliable surge clamping to protect connected devices.
  • 8-wire compatibility with a robust spring-loaded design ensures secure, durable connections even in demanding environments.
  • Compact, easy-to-integrate protection solution that maintains signal quality without introducing significant impedance or interference.

Technical Details of Black Box Surge Protector - RS232/Token Ring, 8-Wire

  • Protection Type: RS-232 and Token Ring
  • Wire Configuration: 8-Wire
  • Capacitance: Low shunt capacitance to reduce signal loss
  • Technology: Avalanche diode technology
  • Construction: Spring-loaded terminals to prevent wire loosening

How to Install Black Box Surge Protector

  • Power down all equipment and disconnect from any power sources before installation to ensure safe handling.
  • Identify the RS-232 and Token Ring interfaces that will be protected and prepare the corresponding 8-wire connections.
  • Position the surge protector in-line with the signal path, ensuring that each of the eight wires is routed to its matched terminal or connector as specified by the device’s installation guide.
  • Engage the spring-loaded terminals to securely clamp each wire. Verify that every connection is snug and properly seated to prevent loosening during operation.
  • Reconnect power and perform a functional test of the connected devices. Check for stable communication, minimal error rates, and absence of abnormal voltages or spikes on the protected lines.

Happy with these boots
Nice-looking and more comfortable than expected for a pointy toe—I’ve worn them a lot for events.

Absolutely soft leather
Color: Coffee
I ordered the coffee color, absolutely love it.Super soft- I have ordered brands that cost 4xs as much & returned because of stiff leather. The zippers simply glide.I love all the different zipper pockets, I like having a place for everything, my phone fits perfectly in the back side zipper area. The front magnetic for my key fob.Zipper above to get out quick cash.I had a hard time deciding which color I wanted! It's roomy enough inside but not too big where Im going to carry things I dont need. It's nice having 2 straps to trade out- im starting with the guitar strap- like that it is adjustable straps & on swivel hooks.And you can really smell the genuine leather. For my preference I would have liked it to have been 2 to 3 inches shorter height wise as I was looking to replace a few bags I used when flying but this is perfect for an everyday crossbody.This bag looks very well made. Nothing fancy on the inside. Plan on searching for this brand in smaller size and some soft colors for spring & summer.

Definitely would recommend
Color: Brown, Color: Brown
This bag had soft leather and looked just like the picture on the product page. There is the main compartment, two zippers and two slip pockets on the inside. I do like the bag, but I don’t usually like slip pockets because a lot of times when you’re just throwing things into the bag items might go into a slip pocket without you realizing it. I didn’t pay attention to this when I bought the bag, but I still really like it. On the back is a large compartment with a zipper. On the front is another large compartment with a zipper and a pocket with a magnetic snap. I bought the brownish color one and it’s really beautiful. I would definitely recommend it. It does come with two straps I am trying out the one they call Boho for now. It is very nice. The other one which I guess is leather also is much thinner.

STURDY, WELL MADE, AND ATTRACTIVE BUT..
Color: Coffee
The title say everything there is to say about this purse. I especially loved the two outside pockets that worked perfectly for my phone, keys etc. making them easily accessible. Unfortunately the inside zipped compartment that many find useful was the bane of my life.. I could not remember whether I had put something inside the zipped pocket or on either side - and if so on which side. Besides which all small things (lipstick, small pill case, etc) fell on their side and were very difficult to see and find in the black interior. I guess I am too used to a purse organizer (light colored) which has stiff pockets in which everything stands up vertically. All it takes is a glance to locate what you need.. I had to, almost regretfully, return this purse but lesson learned - only buy a purse minus middle pocket which leaves no room for an organizer.
