1How to use the device
1.1 Bluetooth Optical Probe
The OP-735 is a device for communication between measurement devices that comply with
IEC62056-21 (mode C, E), IEC62056-31, DLMS standards for optical port, such as electricity
meters, gas correctors…with computers, handheld devices, tablets and other Bluetooth-enabled
devices. It is also possible to communicate in transparent mode.
The Bluetooth of OP-735 supports both Classic and BLE (Bluetooth Low Energy) modes. All
process steps of the optical port, such as pairing, the connection to the meter, and the battery
charge of the device are visible from the device’s LEDs.
The battery is Lithium Polymer with a capacity of 360mAh. It provides 14 hours working time for
each charge. Charging the device through both the adapter and the PC via a USB Type C cable is
possible.
There are some configurations in OP-735 such as Bluetooth name, Optical port frame and baud
rate, mode, etc., that can be changed through Bluetooth commands. All these commands and
