Figure 20. Lubrizol EIA-485 Additive Injector Communications
Note: Lubrizol labels their EIA-485 communication ports with respect to what needs to be connected to their terminals and not with what the
terminal represents. For example, the terminal labeled Tx- on the Lubrizol injector is actually Rx-, but Lubrizol intends for it to represent where
you connect Tx- of the communicating device.
