Whether you need to setup multiple zones, add expansion units, or both, creating a network for the iGrow1400 ’s is simple.

However, there are a few important details to note. The cornerstone to connecting multiple Grow1400s together is choosing one unit to be setup as the Site Master.

The Site Master performs several important tasks:
- It Controls all communications within the network
- It is the only unit that can broadcast Weather Station data to other iGrow1400™’s
- It is the only iGrow1400™ in the network that can be connected to a computer for remote management.
- It sets the time & date for all iGrow1400s in the network

Wiring - Plan for the first installed iGrow1400 to be the Site Master. Once all units are installed in their proper locations and all sensors tested, you are ready to connect the serial cable Regardless of which units will be Zone Masters or Expansion units, all units must be wired together in a serial fashion as shown.

Note:  we recommend 24AWG Shielded Stranded Wire for RS485 Network

Jumper Settings - Make sure to remove the blue jumper on the Site Master and any following controllers, except for the last controller in the serial network chain. On the last unit of the network chain, the blue jumper must remain installed, or the network won’t function properly. If you’re only connecting two iGrow1400s together, remove the jumper from the first Site Master unit and leave it installed on the second unit.

Programming - The last step in setting up the network is programming each unit to be a Site Master, Zone
Master, or Slave (Slave units are also called Expansion units). Zone Masters and Slaves also need to know which data to pull down from the network (such as weather station, temp probes, and zone setpoints).
