6.2 Bluetooth® Communication
The OELD features a Bluetooth® Low Energy (BLE) interface that allows non-intrusive connection to the OELD using a mobile
device running the OELD app. In addition the OELD bridges message transactions between the mobile device and the Searchpoint
Optima Plus or the Searchline Excel by converting the BLE packet information into RS-485 messages and relaying them to the RS-
485 interface, and vice versa. The OELD does not process, convert or regenerate any RS-485 messages between the mobile device
and Searchpoint Optima Plus or Searchline Excel sensors.
The BLE interface is accessed by a suitable mobile device that supports Bluetooth® Low Energy(BLE).
Refer to the OELD Mobile App User Manual for more information on the Bluetooth® the communication link.
Note
• The BLE (Bluetooth® Low Energy) differs from Bluetooth® Classic. Make sure the mobile device selected has an operating
system that supports BLE.
• The Bluetooth® feature should be enabled on the mobile device to allow it to scan BLE devices nearby.
Refer to the User Manual of the mobile device for details of how to use the Bluetooth® functions of the mobile device.
• The OELD supports BLE point-to-point mode of operation. If a connection is established between the OELD and a mobile
device, it cannot be scanned or accessed by another mobile device.
• If there is no active BLE communication for 10 minutes, the OELD will terminate the BLE connection automatically.
• The communication range will vary depending on the field situation and installation location of the OELD. Optimal range will
be achieved line-of-sight between the OELD and the mobile device.

6.3 Alternative Communications (SHC-1 Hand-Held Interrogator)

If the OELD is being used in conjunction with the Searchpoint Optima Plus or Searchline Excel the sensor can be accessed using the
Honeywell Analytics SHC-1 Handheld Interrogator and the SHC Protection Device. Use the dedicated terminals inside the OELD to
do this.
Caution
The SHC-1 must be not be directly connected to the terminals inside the OELD. Always use the SHC protection device (part no.
04230-A-1025)
WARNING

Note
The SHC-1 has not been evaluated for gas performance in accordance with ISA 60079-29-1(12.13.01).
