BIAB Summit Network Simulator (BIAB SNS)

The BIAB Summit Network Simulator (BIAB SNS) is a companion application to BIAB that is included in the fully licensed application, and which runs within the BIAB environment.  The BIAB SNS was created to support two different activities with BIAB:

  • It can be used as a part of a training session, such as when you are teaching others how to use BIAB.  It will allow you so show, in a classroom setting,  how a competition unfolds, with data flowing from the simulated timer network to a working copy of BIAB
  • You can use it to refresh yourself on what you need to do in order to process and verify the data generated by a very small competition.  In this way you can dust off the cobwebs, to prepare yourself for an upcoming real competition, without having to key in data on a network of Summit Timers.

The BIAB SNS must be run on a separate computer, so that it can communicate with a working copy of BIAB. Both of the computers must be equipped with either a Digi RF Modem, such as the one that is used with BIAB to communicate with Summit Wireless Timers, or with an RS-232 crossover (null modem) cable.
Either of these options allows the BIAB SNS to appear, to the working copy of BIAB, as if it was a network of Summit Timers, all of which, when polled by BIAB, will respond to provide competition information, in near real time, simulating the response of the timer network by providing data to BIAB exactly as if it was coming from a real network of summit timers.

The BIAB SNS is provided as part of the installation package with all licensed copies of BIAB.  It is not included as part of the Demonstration version of BIAB.

In order to run the BIAB SNS, your simply install a copy of BIAB on the computer that will be used as the simulator, then start BIAB running, and instead of opening a Competition File, Open the file named “BIAB Summit Network Simulator.jgl” instead.  Once it has been opened, the BIAB SNS will appear on screen, and start running as a separate application.

Pictured below are two different but typical set-ups for the simulator. One computer runs BIAB, and the other runs the BIAB SNS.  The two computers communicate using either a pair of Digi RF Modems (as are normally used to communicate with real Summit Wireless Timers) or over a wired RS-232 Serial null modem (sometimes called crossover) cable connection.

If you want to use the BIAB SNS, it is suggested that you contact Graham Lindsay directly, so that you can then schedule a mutually convenient time for a telephone call to talk you through its set up and use.

If you want to prepare, this is a better view of an RS-232 null modem (or cross-over) cable.  It has female D9 connectors on both ends, and the wires in the cable are “crossed” so that the transmit signal from one computer is sent to the receive function on the other, and vice-versa.  The connectors are often marked as shown in the photo further below.

If you are using the cable method, then you will probably need to acquire two USB to Serial adapters, such as the example shown below.

If you use Serial-to-USB adapters, you will probably need to install drivers on your computer to make these adapters work.  You may find some apparently-very-cheap adapters advertised on the internet.  Often these have issues, sometimes from counterfeit electronic chips, but also in locating drivers that will work properly on your computers.  If you need assistance, don’t hesitate to contact Graham Lindsay.

A ready-to-go cable will appear similar to this one, and once the drivers are installed, is simply plug and play.
