6.2 BLE Communication (Optional)

OELD features an optional BLE interface that allows non-intrusive connection of mobile device to a
sensor that supports RS485 communication. The OELD bridges message transactions between mo-
bile device and sensor by converting the BLE packet to RS485 message and repeating it onto RS485
interface, and vice versa. OELD does not interpret any RS485 messages from mobile device and
sensor.
The BLE interface is accessed by mobile device that supports Bluetooth Low Energy.
Refer to the OELD Mobile App manual for BLE communication information.
Note: The BLE (Bluetooth Low Energy) is different from Bluetooth Classic. Make sure the mobile de-
vice has an operating system that supports BLE.
Note: Bluetooth feature should be enabled in the mobile device to allow it to scan BLE devices near-
by.
Refer to the Mobile device user's manual for details of how to use the Bluetooth on the mobile device.
Note: OELD is compatible with the BLE Point-to-Point mode of operation only. If OELD is connected
with one mobile device, it won't be scanned by other mobile device
If there is no valid BLE communication for 10 minutes, OELD will terminate BLE connection automati-
cally
Note: BLE communication range will vary depending on the field situation and installation location of
OELD. It is recommended to use BLE interface in the line of sight

6.3 Alternative communications (SHC-1)

If the sensor features an RS485 interface (i.e. Honeywell Analytics optical products) this can be ac-
cessed using the Honeywell Analytics SHC1 Handheld Interrogator and the SHC Protection Device,
by direct connection to the terminals inside the OELD.
