I connected Round gauge to my 500hp golf 1 as secondary log and monitoring system during my test runs.
Round Gauge was outside of cockpit secured on the bonnet, I pull cable through the drivers window. Accidentally I lost cable, it pulled out by wind force from Rund gauge and lost same where on the road. So everything working fine O2 and EGT but I can't connect my laptop to Round gauge.
The question is to where connect RS232 Cable inside of Round gauge, and pinout of RS232 connector. I'd like to ask local workshop to make new cable for me. Without communication with Round gauge i haven't logs of o2 amd egt.
Please advise, how to solve this problem.
