Issue
Tolerances for resistors when used for RS485 bus termination and EOL for double balanced inputs.
Product Line
Security Expert
Environment
Wiring
Cause
Resistor specification required for ordering purposes.
Resolution
330 ohm EOL resistors are required for the RS-485 bus and 1K ohm resistors for EOL zone (input) configuration.
- 330 ohm = 5% tolerance, Metal film
- 1000 ohm = 1% tolerance, Metal Film
