RWSL Components

 

This page contains information that will help you decide which components are required to build an RWSL Unit that will meet your institution's needs.  It does not contain vendor information.  For that, go to the "Recommended Equipment and Vendors" page.  For complete instructions on how to use this page go to "RWSL Node Requirements (Setting up an RWSL Node)".

 

 

RWSL Node:  One RWSL Node consists of:

1 or more RWSL Units + the human infrastructure (techs, admin, etc) to support operation

 

Each RWSL Unit consists of:

1 RWSL Required Base Module

1 or more RWSL lab sub-modules that can individually be served to the NANSLO RDN

 

Each RWSL Lab Sub-module consists of:

0 or more pieces of Support Equipment

1 or more pieces of Lab Equipment

 

 

Components

 

Required Base Module (RBM) contains:

1 Network Switch (with 8 ports/RWSL Unit (on average)+ and all necessary cabling) (~$5,000)*

1 Video Streamer
1 Video Mixer
1 PTZ Camera
1 UPS
1 Networked Power Bar
1 Lab Computer
1 National Instruments Software
1 Video Archive Computer
1 Miscellaneous (necessary mounts, cabling, and other connectors)

Estimated Cost: $24,500 ($19,500 if the switch is already available)

 

Note - All RWSL Nodes require 1 RWSL Unit for each RWSL lab that will be served simultaneously.

 

*A network switch with 8 ports can support 1 RWSL Unit at a time, a switch with 16 ports could support 2 RWSL units simultaneously, a switch with 32 ports could support 4 RWSL Units, etc.  While each RWSL Unit will require one of everything else listed here, only one switch might be needed to support several RWSL Units depending on the number of ports it has.

 

+Each RWSL Unit requires 2 ports for the Required Base Module.  Then depending on the lab to be set up in the RWSL (on average) an additional 6 ports will be required.  So estimating 8 ports/RWSL Unit will result in enough ports for all labs that will need to run simultaneously from a node.  It should be noted, that if only one RWSL Unit is to be set up, it would be best to purchase a 16 port switch rather than an 8 port switch for a lab that might require more than the average 8 ports.

 

To put an RWSL Lab Sub-module together, choose from the Support Equipment and Lab Equipment contained in the following 2 tables.  These Tables are not exhaustive lists as they only consist of the components that have been incorporated into RWSL to date.  These lists will grow over time.

*The microscope quoted here comes from China and there is no North American support infrastructure for it.  This version was originally purchased because of budgetary constraints in the WASc 2 project.  The RWSL techs would prefer to use a North American made microscope from Nikon, but the cost would be approximately $40,000.00 and it would require 2 to 3 weeks of full time LabView programming to adapt the VI for the new microscope.

 

 

Examples of a assembled RWSL Units:

 

First determine which lab or labs you want to serve from your RWSL Unit.  (For this example assume the Air Track.)

 

The RWSL Unit designed to offer just the Air Track Lab will contain:

  1. 1 Required Base Module ($24,500)
  2. Air Track RWSL Lab
    1. Support Equipment
      1. Velmex Frame ($25,000)
      2. Robotic Arm ($53,000)
      3. 3 additional PTZ cameras (3 x $1,000 = $3,000)
      4. National Instruments Hardware ($3,000)
    2. Lab Equipment
      1. Air track ($1,500)
      2. Vernier Data Logger ($600)

(Total: $110,600) (without switch: $105,600)

 

 

The RWSL Unit designed to offer just the Microscope Lab will contain:

  1. 1 Required Base Module ($24,500)
  2. Microscope RWSL Lab
    1. Support Equipment
      1. Nikon camera ($10,000)
    2. Lab Equipment
      1. Microscope ($6,000)
      2.  (optional) Slide Auto-loader

(Total: $40,500) (without switch: $35,500) (To include the slide auto-loader add ~$35,000)

 

The RWSL Unit designed to offer just the Spectrometer Lab (configured for emission spectra) will contain:

  1. 1 Required Base Module ($24,500)
  2. Spectrometer (emission spectra) RWSL Lab
    1. Support Equipment
      1. Velmex bi-slide ($3,000)(only if the Velmex frame is not available)
    2. Lab Equipment
      1. Spectrometer ($5,700)
      2. Discharge Tubes and power supplies ($1,000)

(Total: $34,200) (without switch: $29,200) (if Velmex Frame is already available: $26,200)

 

In all cases additional labs can be added by adding the appropriate Support and Lab Equipment.  It needs to be emphasized that with only one Required Base Module, only 1 lab can be served at any given time.  To serve another lab (not simultaneously) will require the reconfiguration of the unit so that it is ready for the next lab to be served.  Student usage is scheduled for the time that the lab is being served to the network.  To serve another lab simultaneously will require an additional Required Base Module (RBM).  Each lab that is to be served simultaneously requires an RBM.

 

When purchasing equipment, it would be best to purchase the number of Required Base Modules needed to run the number of labs that are expected to run simultaneously and then to purchase an appropriately sized switch to accommodate that number of labs.  Then the cost of each additional lab is just the cost of the support and lab equipment for that lab particular lab since the switch and required base modules are reusable for additional labs that are served asynchronously.

 

If production RWSL Units are being set up then each piece of equipment should be at least duplicated so that should a piece of equipment go down, there is a spare that can be switched into the system so that students won't lose valuable course time while repairs are being made.

 

 

Labs Available and Lab Exercises Supported at Various RWSL Nodes (at time of writing)

Hi Pat,
Yes approximate price would be better. I'll change that.

I don't have the vendor information at my finger tips, but could probably get it. ... How about a page called "Recommended Vendors"? I could add that in a link after each piece of equipment that will lead to the Recommended Vendors page where the reader could find vendor information as well as model number and contact info for each piece of equipment.

OK, thanks for the suggestion.

Ron

Hi Ron~
This looks good! Should we say "Approximate Price" and should we list the names of the vendors for each product? Pat
