Modbus RTU 485 or SDI-12 output; and a five-year warranty and recalibration interval. The MS-80SH has a dome heater, internal temperature and humidity sensors, and a tilt sensor. These internal sensors monitor the stability of the irradiance sensors and ensures proper installation and maintenance. -

Page 7: Installation
Not used U and C terminals are automatically configured by the measurement instruction. If multiple SDI-12 sensors are connected to a data logger, Campbell Scientific recommends using separate terminals when possible. However, multiple SDI-12 sensors can connect to the same... -
Page 8: Programming
For the CR6 and CR1000X data loggers, triggering conflicts may occur when a companion terminal is used for a triggering instruction such as TimerInput(), PulseCount(), or WaitDigTrig(). For example, if the MS-80SH is connected to C3 on a CR1000X, then C4 cannot be used in the TimerInput(), PulseCount(), or WaitDigTrig() instructions. -
Page 9: Modbus Crbasic Programming
The RS-485 output can be directly read by a MeteoPV, CR6-series, CR1000X, or Modbus RTU RS-485 network. Other Campbell Scientific data loggers can use an MD485 multidrop interface to read the RS-485 output (refer to the MD485 manual). Refer to www.campbellsci.com/videos/meteopv... -
Page 10: Mounting Procedure
For pyranometers mounted horizontally, ensure the mounting bracket is horizontal in two dimensions. For pyranometers mounted at an angle, set the mounting bracket angle to the desired angle prior to tightening the mounting hardware.

Page 11: Operation
A C! command follows the same pattern as an M! command with the exception that it does not require the data logger to pause its operation until the values are ready. Rather, the data logger MS-80SH Class A Pyranometer with SDI-12 or RS-485 Modbus Communication... - Page 12 As measurement data is transferred between the MS-80SH and data logger digitally, no offset errors are incurred with increasing cable length as seen with analog sensors. However, an increase in cable length does reach a point when digital communications break down, resulting in either no response or excessive SDI-12 retries and incorrect data due to noise problems.

7. Maintenance and troubleshooting The MS-80SH has no service items that require scheduled replacement. There is no accessible desiccant cartridge to maintain. Use pure alcohol or distilled water and a lint-free cloth to clean the dome, removing smears and deposits. Local conditions and application dictate a cleaning interval. -
Page 16: Appendix A. Sdi-12 Sensor Support
Serial Data Interface at 1200 baud (SDI-12 ) is a protocol developed to simplify sensor and data logger compatibility. Only three wires are necessary—serial data, ground, and 12 V. With unique addresses, multiple SDI-12 sensors can connect to a single SDI-12 terminal on a Campbell Scientific data logger. -

Page 19: Start Concurrent Measurement Commands (Ac!)
The data logger makes a request to sensor X to start a concurrent measurement. Sensor X immediately indicates that it will have 5 X03005<CR><LF> (05) values ready for collection within the next 30 (030) seconds. MS-80SH Class A Pyranometer with SDI-12 or RS-485 Modbus Communication... -
Page 20: Start Concurrent Measurement Commands (Ac!)
This is most commonly implemented when long cable lengths or electronic noise may impact measurement transmission to the data logger. When these commands are used, the data returned in response to D!or R! commands must have a cyclic redundancy check (CRC) code MS-80SH Class A Pyranometer with SDI-12 or RS-485 Modbus Communication... -
