Maselli sensor can be interfaced to ADAM converter as depicted in Figure 1.

`(Figure 1) - Maselli sensors with ADAM connection `

Maselli sensor UR29 communicates with ADAM with RS485 with ==115200==, 8N1 settings. Maselli sensor UR62 communicates with ADAM with RS485 with ==19200==, 8N1 settings.

Maselli sensors communicate periodically (in a unidirectional way) to ADAM sending a string in following format:

|  Field  | Start (1 char) | Adam address (2 chars) | Brix or Temperature value in mA (XX.YYY: 6 chars) | Checksum (2 chars) | Carriage return (1 char) |
| :-----: | :------------: | :--------------------: | :-----------------------------------------------: | :----------------: | :----------------------: |
| Example |       #        |           01           |                      02.145                       |        CkCk        |            Cr            |

Be aware that the value is already in mA, so the range must be configured in the UR:

* 4 mA--------------------- UR Brix Low value (ex: 0 Brix)
* 20 mA------------------- UR Brix High value (ex: 80 Brix)

An example of string can be seen in the terminal depicted in Figure 2.
