Setup Of Toggle Switches On The Motherboard - Gree A Series Installation, Start-Up And Maintenance Manual

(2)The CN4 of the display panel should be connected to the unused CN47 at the main
board of the unit though the four-core grounded communication with the shielding
layer. Pay attention that the grounding wire of the communication line is close to the
main board and should be connected to it.
(3)The power lines should be connected to L1, L2, L3, and N at XT1 through a piece of
four-core rubber sleeve cable as shown in the figure above.
(4)There are two solutions for remote monitoring.
1) Install the remote monitoring software at the PC.
2) Based on GREE provided Modbus protocol, the user can do second development
to this protocol.
Note: those enclosed by the dotted lines indicate the remote monitoring equipment.
When the quantity of the display panel exceeds 30 or length of the communication line
exceeds 800m, extra photoelectric relay is required. The photoelectric relays,
communication lines (class 5 twist pairs), converters are optional. PC should be
prepared by the user themselves.

Setup of Toggle Switches on the Motherboard

Five-bit toggle switches are used for indicating hardware address (1~16) of modules, with
module No. displayed in turn on the panel as Module 1, Module 2, ......, Module 16. Toggle
switches 1,2,3,4 and 5 are binary codes, with 1 for the lowest bit and 5 for the highest bit.
Comparison drawings are as follows (Caution: only in the condition of power supply shutoff
can toggle switches be set):
