Notes and Precautions for Installing Wireless
Communication Devices
When installing wireless communication devices take special care in selecting locations so as
to ensure proper communication.
Note that even after a successful installation, due to changes in environmental conditions,
communication errors may occur when restarting the system.
As far as possible, try to keep wireless communication devices away from metals and set
them up in high unobstructed positions.
- Please take note that in many instances, walls, floors, stairs, fences
and desks will contain metals. In order to carry out communication
between indoor and outdoor units, please locate indoor units near a
window so that radio waves can be easily transmitted.
- Please install these devices more than 30cm away from walls or boards
containing metal.
- If wireless communication units are placed in a metal container such as
a freezer or refrigerator, the possible wireless communication range will
be shortened. In most cases radio waves are transmitted via doors
and door openings so place devices as near to doors as possible.
Repeater
(RTR-500)
Place so that the antenna is
away from objects or walls.
As far as possible, keep the devices away from noise-emitting sources.
- Equipment such as some industrial instruments, electronic devices or fluorescent lamps generate noise.
Please place Units more than 1 meter away from such devices.
- Please place Units more than 1 meter away from computers and other devices which emit noise.
- Keep all wires as far away from wireless communication devices as possible. Please be careful about plac-
ing near any wiring or cables such as power supply cables, telephone wires or LAN cables.
Objects which contain lots of water, such as plants or soil, absorb radio waves. We highly
recommend that such materials should not be placed between or near wireless communica-
tion Units.
- When measuring temperature in a greenhouse it has been reported that as plants grew, communication er-
rors also increased.
- Do not place Units directly on the ground.
Do not place devices which are using the same communication frequency channel in the
same area.
- If the same channel is used for multiple devices not only will more communication errors occur, but battery
life will also be shortened.
- If there is a possibility that devices with the same frequency channel will be in wireless communication at the
same time, please make sure to make changes to the frequency channels so they are not the same.
After having made an installation, check the wireless signal strength.
Checking from the software:
The supplied software application includes a feature to check for wireless signal strength. In the RTR-500DC
Settings Utility, in the [Wireless Route Settings] menu it is possible to check signal strength.
Checking from the RTR-500DC:
In the Main Menu of the RTR-500DC, open [Monitor Mode] - [Specify Remote Unit]; check the signal
strength by looking at the antenna icons displayed in the monitoring window.
