would like to run a wire from a legacy LED display to a desktop pc. both have rs232 9-pin D ports. the sign claims that it can be programmed from a simple communication software.
i have read that rs232 9-pin runs can go a max of 25' (some sites say 50 feet) before requiring a signal booster.
can i use 9-pin D > RJ 45 adapters at both ends and run CAT-5 network cable (+/-300' max run) between them avoid using signal boosters?
the task will involve running approx 120' of wiring through some difficult crawlspaces and attics. would like to avoid having to try to run the CAT-5 just to find out that it too will need a signal booster every 25'. there is simply nowhere to easily get power to the signal boosters, once they are in the walls and attics.
any thoughts?
TIA
