Figure 13
If the option board (radio module) in the meter is an OMS T2 type, the set-up should be as follows:
• Transfer the data from the Main tab, or enter the METER ADDRESS manually.
• Set the options as shown, i.e. tick the checkboxes Meter enabled, 2-way radio, OMS T2 protocol
and Meter data valid (Options in hex = 4B).
• Set Meter install state to 1 as there is no installation procedure.
• Set T1 period (in seconds) to how often the meter is to send out meter data. T2 fraction is not
used.
• Enter the same key in IEK and KEY.
• Rev B barcode is not used.
• For the Option Board data fields, see 3.2 Meter x tabs.
No Encryption on M-Bus:
• Tick this checkbox if the decryption has to be done in the back office (then the Options in HEX
will show 43).
Important for OMS: Both IEK and KEY must be set, and set to the same key.
