The 4x1 3G/HD/SD-SDI ASI Switcher from� Link Electronics �is a four-input video switcher that provides a convenient, low-cost way to route high definition and standard definition serial digital signals. This switcher is compatible with 270 Mb/s, 1.5 Gb/s, and 3 Gb/s serial digital interface signals. It can also be used for ASI and SMPTE 310M (19.4 Mb/s) signals, and the reclocking will be automatically be turned off. This switcher automatically equalizes the incoming SDI signal, compensating for greater than 1,000� of cable at 270 Mb/s, greater than 250� of cable at 1.485 Gb/s, and greater than 100� of cable at 2.97 Gb/s. The signal is then reclocked, with automatic rate detection for all popular data rates. The LEDs on the front panel indicate the data rate of the output video.

This multi-definition SDI 4x1 video switcher is capable of equalizing and reclocking all common serial digital signals, since it supports both standard and high definition signals. This makes it suitable for any application. The switcher�s versatility is illustrated by its ability to switch from SD to HD, SD to 3G, HD to 3G, and vice-versa. Another feature of this switcher is its ability to vertical interval switch when the inputs are synchronous. Vertical interval switching means that the switching takes place in the vertical interval of the video and therefore no glitch is seen in the active area of the video.

The 4x1 3G/HD/SD-SDI Switcher is a 1 RU chassis that is housed in the same case as the well-accepted 700 series. A black front panel distinguishes between the two series. Three 500 or 700 series can be mounted in the PRT-700 rack tray (sold separately).

New Rope for my Pit Bulls
Style: 5 KNOTS
When I received this from Amazon delivery my pit bull mix went crazy on the rope, and she chew on it for the longest time. Then, I played keep away but that lasted a short time. The rope is very strong and long for me to play with my pit bull mix she wants me to play tug a war with her. She will win every time, I do enjoy her every day, makes me happy that she mine. Price is very reasonable and color was very good and lasted a long time too. I buy again soon as she wear this one out.

Best toy for big dogs
Style: 5 KNOTS
This is the toughest rope I have found. It is the only toy my Rottweiler doesn’t destroy in a day. It lasts over a week with her constantly carrying it around and tearing at it. She loves it.

Adorable and Great Quality
Style: Bundle
These toys are the best! They are perfect for a little 4lb. rescue poodle. He’s finally starting to play! Each toy has different squeaky sounds and textures. The packaging with the dog logo was cute, too!
