Environment
RS-485

Resolution
The maximum number of devices that can be daisy chained out of the PowerLogic Network Interface Module (PNIM) RS-485 port are 32, without using repeaters. The maximum length of the daisy chain is dependent on the baud rate of the devices. See table below.

Typical maximum RS-485 Drive Distance

Baud Rate	150-9600	19200	38400	57600	115200
Distance (feet)	4000	3200	3000	2300	1600
Distance (meters)	1220	975	914	701	488

*Note: Based on 24 AWG twisted shielded pair, 0.026 Ohm/ft (0.085 Ohm/m), 13pF/ft(41pF/m) conductor to conductor, 22 Pf/ft (72pF/m) conductor to shield.
