Astro Satellite TV Decoders

A stack of Astro decoders connected to a WISI OV38 modules in a soon to open hotel.

 So here's one side of that stack, there are two of these. On the left if the front and on the right is the back. I was planning to make custom made RCA connectors but we were doing on this in a hurry. Plus we ran out of the compression F connectors and this has to be done within the day because there will be a dry run of everything the next day.

We managed to finished it on time. Thankfully.

With all the decoders and modules connected it's time to send them the TV Signal to each floor. Each floor has its own TV signal booster and all floors have cables running back directly to this WISI DM08 Splitter. It only takes a few moments to think about it but the actual work done took a whole lot of time especially when you are doing such installation by yourself only.

Now that its done all the room and TVs in the building are receiving the signal, so next post will programming each TV in the building.

New Hotel TV System Using WISI OV50 and OV38

About a month ago we were checking an old Televes TV system in one of the hotels in my area.
After taking a look at the TV system it came out that some of the modules aren't working anymore and some of the channel subscription are not worth the extra amount to buy a replacement module. The cable have been redone by numerous technicians over the years and no documentation was made. It took a while to know which cable goes to  where. 
The owner wanted a new system and thus they ordered some WISI items one OV50 and six OV38, this will only give 12 TV channels, each channel with stereo audio as the OV38 is a dual channel module.

The OV50 has two identical RF inputs to accommodate the modules from the each side, then there is a connection for RF which you then connect ot the AMP IN if you are going to use the built signal booster in the OV 50 unit. AMP OUT goes to your RF distributor which then goes to the room TVs. Setting up the radio frequencies on each modules is easy. You just have to choose which channel ( channel A or channel B) you are going to set to which frequencies. This can all be done by using the display and buttons on the front of each modules.

This time we labeled all the cables and documented the work we did so that it will be easier for the next guy who is going to check the tv system after us.

The AV source of the modules are from anconnected to 10 Astro B-yond decoders and 2 channels from aerial decoders.

I would've preferred to put each unit in a shelf and even offered to fabricate it since those weren't available but my superior insisted that stacking the units like this would be just fine. At least It looked neater than the older set up.

.... more to come time to go make a living again....
