RemoDAQ-8017S User’s Manual 

set data format to engineering units 

(See Chapter 3, Command Set for a full description of the 

syntax of the configuration command for module) 
When the module received the configuration command it will 
respond with its new address

：

!07(cr) 

NOTICE

：

  All reconfiguration except changing of baud rate 

and checksum values can be done dynamically, i.e. the 
modules need not to be reset. When changing the baud rate or 
checksum, these changes should be made for all connected 
devices. After reconfiguration, all modules should be 
powered down and powered up to force a reboot and let the 
changes take effect. 

 

2.4 Baudrate and Checksum 

RemoDAQ modules contain EEPROMs to store 

configuration information and calibration constants. The 
EEPROM replaces the usual array of switches and ports 
required to specify baudrate, input/output range etc. 

All of the RemoDAQ modules can be configured remotely 

through their communication ports, without having to 
physically alter port or switch settings. 

Forcing the module in the INIT* state does not change any 

parameters in the module’s EEPROM. When the module is in 
the INIT* state with its INIT* and GND terminals shorted, all 
configuration settings can be changed and the module will 
respond to all other commands normally.
