The installation requirement of Smartlink
(1). The Connection requirement of wireless communication system
For the MRV system adopting wireless communication, it is recommended to adopt the mix-connection solution
of wired and wireless communication, namely the master ODU connecting with one nearest IDU by wire and all
IDUs adopting wireless communication with each other within the system. The ODU does not need to be equipped
with a wireless module. The first indoor unit connected to the outdoor unit is used as the main IDU . The main
IDU wireless module(IGU09) needs to be installed, and the slave IDU wireless module (IGU10) are installed the
other IDU. (Note: for the MRV 5-RC system, the outdoor and all the valve boxes must be connected by the wires,
the indoor unit which is not connected with valve box must be connected by wires, the valve box as the main IDU,
indoor units connected with valve box as the slave IDU)
(2) The installation requirement IDU wireless module
a. If IDU wireless module as standard module means its installation has been finished before delivering. If as
optional module, it needs to be installed in the specific location, with communication wire connecting to CN 34 port
of IDU PC board.
b. The antenna of the IDU wireless module is rotatable. Keep the antenna more than 10cm away from metals
c. Keep the IDUs with wireless module more than 10m away from the Wifi devices in the room.
(3) The installation requirement of Repeater
a. Add one repeater when the distance between any two wireless modules (both ODU wireless module and IDU
wireless module) exceeds per 100m.
b. Add one repeater when there is one wall or other similar buildings between any two wireless modules, both
ODU wireless module and IDU wireless module.
Remark: Do not need to add the repeater when there is only one wall between ODUs and ODUs
c. Repeater should be installed in the open space as far as possible, especially keeping the antenna more than
10cm away from metals
d. Repeater must be supplied power separately by its own power adapter. The installation of the repeater should
consider the convenience of connection to external single-phase 220V AC power supply and the required
waterproof position.
Remark: According to the above requirement, the number of repeaters to be installed should be calculated in
advance . Adding the repeaters based on above requirements can ensure the reliability and stability of wireless
communication system.
(4) The installation requirement of IDUs
a. For the system adopting wireless communication , the installation of IDUs should use network structure instead
of line-type structure;
b. Do not install the IDUs in the space surrounded by metal, such as metro computer room and hospital X-ray
room, otherwise the system should adopt the wired connection.
c. Keep the IDUs more than 10m away from the Wifi devices in the room.
