Page 12: Installation Hints For Best Performance
Installation Hints for Best Performance This section offers several suggestions which will help you get the best performance from your system. RS232 and RS485 use comparitively small signals which can easily be corrupted by the potentially high level of electrical noise which can be created by electrical machinery such as motors, welding systems, discharge lighting, AC power inverters and solenoids. - Page 13 When using multi-core screened cable to connect several displays to several data sources, please be sure to use one twisted pair for each display and sensor. Do NOT use a wire from one pair for signal positive and a wire from another pair for signal negative, as this will prevent the twisted cables form cancelling any induced electrical noise, and can couple noise from one source to another.
