1350 -
1351 -The RS485-LN can support max 32 RS485 devices. Each uplink command of RS485-LN can support max 16 different RS485 command. So RS485-LN can support max 16 RS485 devices pre-program in the device for uplink. For other devices no pre-program, user can use the [[downlink message (type code 0xA8) to poll their info>>||anchor="H3.3.3Configurereadcommandsforeachsampling"]].
