Whyte Multiswitches &IRS Equipment
NEWS & INFO / Using WOSP Whyte System Planning Online
Date Created: 04-10-2019

In this week’s Technical Post we are looking at the IRS components we’ve touched upon in the previous post and start to put these together using our free Whyte Online System Planning tool (WOSP) as a schematic diagram. You can use this short cut to take you directly to WOSP

On opening the link you will have access to the online application, depending on your internet connection and processor speed you may need to wait a few moments while the platform loads. On the left-hand side you will see the Whyte IRS component library. The page size defaults to A4 Portrait but this can be changed under File and Page Setup to your preferences. At the bottom of your drawing space there is a template to fill in the project details. You can double click a box and enter the details of your project. You can navigate the drawing space using the scroll bars of the web page window and the drawing space. Tip: In the drawing space click an open area once, then hold Ctrl, click and hold then you’ll be able to drag the drawing space around and zoom in and out with your mouse wheel.

Let’s continue by adding some basic elements, from the Array Library drag in a 5 Wire Array to the middle top of your diagram (when you mouse over a library component more details will be shown). With the Array selected you can nudge its position with the cursor keys, holding shift at the same time will nudge in larger steps. I suggest nudging to the nearest thick line of the grid as this makes alignment easier. Referring back to last week’s post we have a three floor building (ground, first and second). Let’s add those floors in. In the floors library you’ll find a Floors Library where you can drag these in from. Space them out evenly. Tip: Use the Arrange function from the drop down menu to help you align these elements.

Were now ready to start adding our Whyte IRS components, let’s start by placing six WSCR506 dSCRs two on each floor. You’ll notice these are vertically orientated, but if you click select the shape and click the dSCR graphic you can click the circular arrow to flip the orientation (in steps of 90°) to the position you require. Tip: Zoom in to see the detail of the orientation you can also click the Whyte part number to nudge this into a preferred position. Let’s join the pairs of WSCR506s together (drag them close and nudge the interfaces together). We can now terminate the WSCRs with our WM512 Multiswitch. From the component library drag over three WM512s and place them at the end of your pairs of WSCR506s. We’ve now created the chains we need for each floor, but we still need to get the signals to them. On the first floor add a WS52-05 Splitter this will feed signal to our chains on the Ground floor and the First floor. Above that on the Second floor lets add a WT51-10 Tap (-10dB on the Tap output).

Note: When you mouse over a component on your diagram a small pop-up will show you additional information about the properties of that device (signal loss and available gain for example).

As there is a significant number of devices with their respective through losses were going to need some amplification, let’s place a WATS-530 Launch Amplifier on top of the WT51-10 and you can connect your WATS-530 to the Antenna Array. If we know the cable drop distance from the roof to the Launch Amplifier then we can drag that in from the Grids and Labels library. Finally we can add a quad outlet plate and draw one line from a dSCR output and one from the WM512 Multiswitch to the quad plate. A label can also be placed to indicate the run cable distance from the Multiswitch.

As with any software save your work often. When saving I recommend saving to your device, options for various cloud storage platforms are available too (if you have this setup). You can also export your diagram in various formats I recommend pdf.

Next week were going be making system calculations.
