Discover a leading-edge solution for reliable serial data delivery over long-distance fiber. The Black Box FlexPoint Modular Media Converter converts RS-232 signals to fiber optics, enabling robust, noise-immune communication between serial devices and remote equipment. Built to operate as a standalone unit or as part of the FlexPoint family, this converter is ideal for point-to-point industrial links, campus networks, or data-center edge deployments where distance and EMI are critical concerns. With single-mode fiber up to 30 kilometers, SC connectors, and autosensing data rates up to 115.2 kbps, it delivers flexible, scalable performance without complicating cabling. The unit ships with a power supply and supports the space-saving FlexPoint Power Chassis to power multiple units in a 19-inch rack. Its DTE/DCE configuration makes connections to either side straightforward, minimizing setup time and reducing the risk of misconfiguration. In short, the FlexPoint RS-232 to fiber converter combines ease of installation, rugged reliability, and modular expandability to meet growing serial communication needs.

  • Autosenses speeds up to 115.2 kbps, delivering efficient serial data transmission while preserving signal integrity over long distances on single-mode fiber.
  • Offers flexible deployment as either a standalone converter or a hot-swappable, chassis-based extender within the FlexPoint system for scalable, modular growth.
  • Includes a power supply out of the box and supports power distribution to multiple units through the compact 19" FlexPoint Power Chassis, saving rack space in dense deployments.
  • Features a clear DTE/DCE configuration to simplify connections to host devices or network equipment, reducing setup time and misconfiguration risk.
  • Designed for straightforward installation and operation with plug-and-play usability, intuitive indicators, and robust performance in demanding environments.

how to install Black Box FlexPoint Modular Media Converter

  • Unpack the unit and verify all components, including the converter, power supply, and any accompanying manuals or documentation.
  • Identify the RS-232 connection on the converter and prepare the single-mode fiber link with an SC connector from the remote device.
  • Connect the RS-232 host device to the converter's serial interface and attach the fiber optic link to the SC port, ensuring the connections are secure and free of dust.
  • Power the converter using the included power supply; if you are deploying multiple converters, place them in a FlexPoint Power Chassis and connect the chassis to a suitable power source.
  • If using a FlexPoint rack, slide the converter into an available 19" slot and secure it as needed; verify that the front-panel indicators illuminate to indicate power and link status.
  • Configure the DTE/DCE setting to match the role of the connected devices on both ends, and ensure consistency to avoid negotiation or link errors.
  • Power on the system and perform a basic handshake test by sending a diagnostic sequence from the RS-232 side and confirming successful reception on the fiber-connected side.
  • Document the installation, including device roles, port settings, and link distance, to facilitate future maintenance or expansion.

Doesn't last
Size: 2.5" x 5.1", Size: 2.5" x 5.1"
This grinder appeared to work great and is one of the few ceramic options available. Unfortunately, the ceramic grinder has already broken inside, detaching from the bottle altogether. There are probably tiny plastic pieces in my leftover peppercorns. Don't buy it unless you want to purchase it every few months, which is unfortunate.

Very nice, work well, good gift at a reasonable price
Size: 2 Count (Pack of 1)
I've owned a few different brands and types of grinders before, and these are quite similar. The last set I purchased had the exact same grinder heads, just on smaller glass bottoms. The grinders on those became, unfortunately, unusable due to clogging that resulted in breakage of the ceramic gear. I worry that, since these new grinders have the same heads on them, that these won't last longer than the last set. However, I read reviews of the "best" grinders out there, and these came just behind a more (much more) expensive set with metal gears instead of ceramic. They'd last longer, you might think, however, it was also mentioned that salt corrodes metal and so that's why the vast majority of grinders, mostly intended for use with salt, are made of ceramic. So why would I spend five times the price on the expensive ones? So far, I'm very pleased with this set. They're much more comfortable to use than my previous set, which had way smaller glass bases. I can really get a good grip on these. The little "dial" on the bottom, to adjust the coarseness of the grind, moves very smoothly on these. It was so difficult to turn the dials on the previous set - and mind you, these are exactly the same as the new ones - that I had to use a pair of pliers to turn them. Strange. I see this identical grinding mechanism on several of the grinders available on Amazon, so it makes sense to assume they're all sourced from the same manufacturer by different vendors. These also hold about twice the amount as my previous set - not a major hassle to refill, but nice not to have to bother with it as often. Quite elegant looking, too. The set comes with a nifty metal holder with prongs on either side that the grinders snap into place securely for transport from kitchen to dining table. They're inexpensive enough that you can easily afford to buy two sets for each end of your table. That's a nice touch if you're having several dinner guests or a large family, so you don't have to pass the salt and pepper around. I guess the $100 set with the metal gears might last longer, even with inevitable salt corrosion, but these will likely last a good long while with their ceramic gears and, if they do break down sooner, at least you could buy four or five of these sets for the same price. I recommend this set.

Love, Love, Love
Size: 2 Count (Pack of 1), Size: 2 Count (Pack of 1)
THIS SET, I LOVE! Absolutely love. When you buy something that you can't see and physically touch- You're always rolling the dice And whether or not you'll like what you receive.. I have bought a few grinder sets in the past, use for a bit and then toss, and back to buy another. This set is a keeper! It washed well, was easy to fill with a wider mouth opening and the grider worked perfectly. I also like having the ability of changing the coarseness, as our household members have different preferences. Looks nice on my table, and the stand was an added bonus. The size is large enough to not have to refill as often but not to big to look out of place. A good price, they look nice, nice grip and durability. I will be buying a couple more sets as gifts to those that have been here for dinner and mentioned that like them as well. I have no 'cons' to list on the product. I love everything about it. Look no further- you'll be pleasantly pleased.

Great value for the money the set works very nicely
Size: 2 Count (Pack of 1)
This is a nice set of Peppermill and salt grinder. The capacity is very nice and it is easy to clean. It’s made of sturdy glass and the top is a very nice stainless. It’s the perfect size for my hands and it distributes a very nicely, ground pepper and salt. I had to switch the salt and pepper from one shaker to another because one was not grinding the peppercorns, but when I switched it to the other, they both worked fine.

Easy to use, pepper doesn't get stuck
Size: 2 Count (Pack of 1)
I'm never going back to an electric grinder again!!! I like my pepper on the fine side - I don't like to bite into a chunk of peppercorn. With those electric grinders, the peppercorns get stuck and the motors don't have enough 'oompf' to plow through. This handy dandy grinder absolutely does! I'm able to easily adjust the size of the grind and the mechanism is smooth and easy to handle. The shape feels good in my hand and the 1/2 cup container is a great size. You don't have to refill it too often. Between the shape of the grinders and the holder, I feel it looks nice on my table. I couldn't be more pleased!!
