I. SYSTEM INDICATION MODE
The power status of the device is visualized when LEDs are in system mode. The device offers 5 LEDs for
the system status. System mode is explained with the text markings above the LEDs.
USB: USB Powered (red LED) ON when the device is connected to a USB port.
CHA: Charger On (yellow LED) ON when the battery charger is on.
II. SIGNAL LEVEL METER INDICATION MODE
The device offers 5 LEDs for the RSSI, which means that 5 different signal strength levels are visualized.
Levels are printed on the plastic enclosure of the device.
LOW: Battery Low (yellow LED) ON when battery is low. Always off when USB powered.
CUT: Cut off indication (green LED) When ON, the device will be powered off within the next 20 seconds.
Always off when the device is normally operating.
I: No signal (red LED) Do not install any wireless luminaires (or other device) in this area.
II: Poor signal (yellow LED) Avoid installing wireless luminaires (or other device) in this area,
communication losses might exist.
SYS: System Mode Indication (green LED) Always blinking with 1Hz (0.5s off/0.5s on) when in system
mode.
III: Medium signal (yellow LED) It is safe to install a wireless luminaire (or other device) in this area.
IIII: Good signal (green LED) It is safe to install a wireless luminaire (or other device) in this area.
xRestore communication of wireless devices (luminary / other) which were unresponsive during
commissioning.
CONFIGURING SID AND RF CHANNEL SETTINGS
Installation Tool is used to set specific wireless devices (luminaries, other) to join an existing wireless
network with configured SID, RF Channel and NKey settings.
When adding new wireless devices into an existing wireless network, it is recommended to use the RSSI
Tester to check signal level at the installation points. If the SID, RF Channel and NKey parameters of the
wireless network have been changed, you will have to apply the same parameters to the RSSI Tester
device in order to be able to detect signal. For this task, connect the device to a PC via USB and run
“Wireless Installation Tool” app. While the device is connected, click on “Scan” and the USB identity
of the GR-7605/V2 appears on the box on the right as selected. Then click on “Connect”. When “UID”
value of the device appears, click on “RSSI Tester”. Under the “New Values” area, write the wireless
parameters of the wireless network to be scanned and click “Change”. Disconnect the device from USB
cable and wait 10' until it powers off. Now, when powered on, the GR-7605/V2 will be able to detect signal
from that specific wireless network.
IIIII: Excellent signal (green LED) It is safe to install a wireless luminaire (or other device) in this area.
IMPORTANT: SID, RF Channel and NKey values are stored permanently in the device's memory.
Custom SID, RF Channel and NKey settings will be maintained in every operating mode. To measure a
new wireless network with default values, you must restore the SID, RF Channel and NKey values back
to default (00000001 / 2 / 00000000).
In cases where the Signal Level is not stable, but slides between 2 levels, the only rule is to select a better
spot when the Signal Level slides between “poor” and “medium” (II – III). This means that the signal
sometimes falls below “medium” level, so installing a device at this spot is not recommended. The two
LEDs at the bottom of the device are always on when the device operates as RSSI tester.
Every time the device is powered on handheld, starts in RSSI Tester mode.
2. INSTALLATION TOOL
x Replace, or add new wireless devices (luminary / other) to an existing wireless network with custom
SID and RF Channel settings.
To use a GR-7605/V2 as Installation Tool, connect the device with a PC via USB and run “Wireless
Installation Tool” app. While the device is connected, click on “Scan” and the USB identity of the GR-
7605/V2 appears on the box on the right as selected. Then click on “Connect”. When “UID” value of the
device appears, click on “Manual Installation Tool”.
x Commissioning of multiple wireless networks in parallel.
