691 is a high−performance HDBaseT 2.0 fiber transmitter for ultra−reach extension of 4K60Hz (4:2:0) HDMI, USB, Ethernet, RS−232, IR and stereo audio signals over either multi−mode or single−mode fiber optic. 691 converts all input signals to an HDBaseT 2.0 signal that is transmitted over a fiber optic cable to a compatible receiver that converts it back to the HDMI, USB, Ethernet, RS−232, IR and stereo audio signals. It extends video signals to up to 33km (20.5 miles) over single−mode fiber at up to 4K@60Hz (4:2:0) resolution. 691 includes a multimode OSP+ transceiver, but can be used with a single mode OSP+ transceiver and fiber as well.

  •  High Performance Standard Fiber Extender — HDBaseT 2.0 fiber transmitter for providing ultra–reach signals over either multi–mode or single–mode optical fiber infrastructures, using Kramer pluggable OSP SFP+ units. 691 is a standard fiber extender that can be connected to any market–available HDBaseT–compliant extension product.
    Note: To ensure specified performance, support, and warranty of this product, use only Kramer's certified hi–performance OSP SFP+ pluggable optical units.
  •  HDMI Signal Extension — HDCP 1.4 compliant. Supports deep color, x.v.Color™, lip sync, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0. EDID and CEC signals are passed through from the source to the display.
  •  I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID handling, processing and pass–through algorithm that ensures Plug and Play operation for HDMI source and display systems.
  •  USB Extension — USB 2.0 interface data flows in both directions, allowing extension of HID (Human Interface Devices) peripheral devices, such as a mouse or a keyboard. High–bandwidth USB peripheral devices, such as USB isochronous streaming cameras and audio devices, transfer data continuously and periodically.
    Note: Delivery of their transferred data is not guaranteed by the USB standard and is subject to both USB and HDBaseT line bandwidth management limitations. When such devices are connected, check their functionality to ensure bandwidth limitations are not exceeded.
  •  Ethernet Extension — Ethernet interface data flows in both directions allowing extension of up to 100Mbps Ethernet connectivity for LAN communication and device control.
  •  Bidirectional RS–232 Extension — Serial interface data flows in both directions allowing data transmission and device control.
  •  Bidirectional Infrared Extension — IR interface data flows in both directions allowing remote control of peripheral devices located at either end of the extended line.
  •  Audio Embedding (Adding) — A selectable analog unbalanced stereo audio input is converted into a digital signal and embedded (added) to the transmitted HDMI signal, replacing the embedded HDMI audio input signal. This enables embedding a selectable audio source over HDMI. For example, a presenter can display a video clip and temporarily override the audio of the source media with another audio source, such as from a microphone.
  •  Cost–Effective Maintenance — Status LED indicators for the HDMI input and HDBT output link facilitate easy local troubleshooting. Remote device management via built–in web UI and RS–232 connection enable simple device maintenance. Local and remote firmware upgrade via mini–USB, RS–232 or Ethernet connection and the K–Upload tool ensure lasting, field–proven deployment.
  •  Easy Installation — Half 19” 1U rack mountable fan–less enclosure enables side–by–side mounting of 2 units in a 1U rack space.

Top Class Watch
Color: sliver band blue face-G5885G
I really love this watch, its very bright in the night, it was very easy to set the time on it, I also love the weight of this watch, it's definitely of top class quality, thankfully I didn't need the tool to adjust the band because it fit perfectly fine, plus the quartz system is working quite well, hasn't missed a second since I set it. Time keeping is amazing. Overall, I love this watch so much, I'm thinking of buying the black face one as I bought the blue face one.

Tracking Process & Quality of Product
Color: Black Watches for Men/Black Dial-2870
I don't know where to review the tracking process so I will do it here. I just love the fact that they list stop by stop where your order is. I ordered this for my son for his graduation present and was very excited to give it to him. I was able to see how many stops the driver had before he got to me which allowed me to not only have a better idea of its arrival time, but I was also able to enjoy a buildup of excitement as it got closer and closer. As for the quality of the product ~ both my son and I are very impressed and more than satisfied with the watch so far. I was very trepidatious as so many items, especially jewelry items, look stunning, gorgeous, beautiful, high quality in the pictures online and are nothing short of utterly disappointing when you get them. This watch renewed my belief that there are honest sellers out there. I will say that we just got the watch today so this is purely about the initial presentation and look of the watch. So, the packaging was super nice, high-end quality. Each piece (bands, watchface) were separately wrapped in nice, thick plastic to protect from scratching. The boxes (box for watch & slip cover outer box) were great quality (you know, so many companie's packaging falls apart at barely a touch, which makes me wonder about the quality of what's inside). Thorough, grammatically correct (mostly) directions included; also had tools for taking out links along with fairly easy to follow pictured & written directions. We did have to use a separate pin with a head (like tailors use to mark hem points) to push out the pins bcz the one included bent. One thing I really appreciate is that the company said they are there anytime and to please let them know of any issues. Usually companies do all they can to make it as hard as possible to be contacted. I couldn't stop looking at the watch! It DEFINITELY looks SO MUCH MORE expensive than it was! And the workings move like a Rolex (smoothly), not jumpy like the workings of normal watches. Even my husband remarked on how "Rolexey" it looked. I ordered the all black watch. Again, we've only just gotten it, but if the initial presentation is any indicator of its performance, WE'VE GOT A WINNER!!

Good looking cost effective

Good for the price. Looks nice from a distance. Feels heavy. Is a bit noisy when you walk. But value for money.

Low cost watch returned.
Color: Gold Silver Stainless Steel/Black Dial-2870
I returned this watch the next day after receiving it. It was very attractive and I hope it would work as advertised. The watch came in shrink wrapped plastic that was very tough to removed. I feared damaging the watch. I set it then tried some of its features. The stopwatch worked but it did not reset to the zero position properly. The 24 hour time indicator was off by one hour. The rotating bezel had black lacquer on it that was tender to the touch. A fingernail could have damaged it and a very small nick had already started out of the box. If everything had worked properly I would have kept it for the money spent. I guess you get what you pay for so I am now shopping for a higher quality watch.
