There are two ways you can do this.
In the DOS version you need to have one of the old SPlit Second bidirectional input /output cables. This basically allows the single serial port to work for input of data from the timer and output to the display. The Cable also allowed the software to send the hex codes to the timer , forcing it to use 2400 baud output.
In the windows version you can specify a second serial port that can operate at 2400 baud while the input works at 4800 baud. There are several options availible. I like using SOCKET brand PCMCIA cards availible from
www.pcconnection.com or
www.mobileplanet.com You can also use USB > serial adapters.
From SST site:
Timer AND a Scoreboard (1 serial port versus 2)
When connecting a Timer and a Scoreboard you are obviously connecting 2 things to your computer. All the timers and scoreboards capable of interfacing with Split Second Software attach via a serial port. It's best, if possible, to have each of the devices on it's own serial port, but it might be possible to use one:
2 serial ports : This is the best option because it simplifies connections and lets you test either device with the knowledge they are completely independent. It also means you can connect any Timer and any Scoreboard. If using a desktop computer this usually isn't a problem since most desktops come with 2 ports. But a
notebook computer usually only comes with 1 standard serial port. There are 2 basic ways to add another serial port:
USB to Serial DB9. Most newer notebooks have a USB (Universal Serial Bus) port. Simply purchase an adapter and install (relatively simple to install) and the problem is solved. We recommend the Xircom adapter available from the following many on-line computer vendors including: CDW.com Dalco.com
PC Card to Serial DB9. Not as ideal as the USB option but some older computers that don't have a USB port do have a PC Card slot. Installation is slightly more difficult (not usually plug-n-play) and more expensive. Available from: B&B Electronics
Remember to make sure that the serial port is recognized by Windows "device manager" before proceeding to software.
