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.
