Current Versions of Base Radios

• All models of BR20 and BR21 (DIN rail mounted) base radios are equipped with Modbus.
• Current model numbers of the BR10 (NEMA 4X enclosure) TBUABR10-xyz are equipped with Modbus.

Previous Versions

Model AC-BR10 (similar to the current TBUARBR10 models)

BR10 with Modbus would have a model number similar to AC-BR10-TX21N00, where the 1 indicates Modbus is available. A model number similar to AC-BR10-TX20N00, with a zero, would indicate no Modbus capabilities are available on this model.

Model WI-BR (similar to the current TBUARBR10 models)

A different model number scheme was used when Adaptive Wireless had the Accutech product line.
A model number such as WI-BR-I-XP-MOD would have been enabled with Modbus. A model number that does NOT have -MOD may or may not have Modbus.

If -MOD is not listed in the model number, you will then need to have a look at the circuit boards inside the base radio. A WI-BR with three boards would have Modbus, whereas there would be no Modbus capabilities if only two boards were present.

WI-BR with Modbus (3 boards present)


WI-BR without Modbus (2 boards present)


If you have a Base Radio without Modbus and wish to enable it, the upgrade would be more expensive than purchasing a new radio. It is not a cost-effective upgrade and can not be performed.
