- Hi.
- During the world's largest estafette(=relay race?) (Batavieren-race,
- over 6000 participants, see Guiness Book of Records) I have to gather
- as quickly as possible a preliminary ranking.
- We do this by timing all runners at several points along the track. The
- timing-data is read into a computer (PC/XT/AT/?86 whatever) and
- simultaneously sent by packet-radio to a second computer near the finish.
-
- Most of the software is up and running and we're up to adding some
- extra's. One of these is a second monitor which continuously shows
- the last 10 teams arrived at the relay-point and the teams ranking
- 1 through 10.
-
- Of course we don't want this monitor close to our own car or near the
- computer near the finish-line, because of the curious crowd gathering
- around this screen to see how they have done so far.
-
- What we _do_ want is this:
- A PC with a (colour) monitor
- a second monitor, connected using about 100 m. coaxial cable
- while the monitor's power supply (12V= )is via the same cable
- the 2nd monitor should be capable of displaying 40x25 characters
-
- As you might guess, we're aiming at using a composite video signal,
- probably from an CGA-card.
-
- Can anybody tell me (in rough technical terms, we're at a university and we
- can get the Electr(on)ical Engineers to work for us) what video-cards
- combinations we can use, how we can have both the power and video-signal
- over the same cable and if there are any alternatives.
-
- Remember, we have to power the second monitor from the van, because there
- are little power outlets in trees and we cannot wake up anybody in the
- darkest of night just because of a second power outlet.
-
- Thanks in advance,
