RemoDAQ s configuration might require the module to perform auto calibration before changes can take effect Especially when changing the range the module has to perform all stages of auto calibration that it also performs when booted When this process is under way the module does not respond to any other commands The command set includes the exact delays that might occur when modules are reconfigured Syntax delimiter character address command data checksum carriage return Every command begins with a delimiter character There are four valid characters a dollar sign a pound sign a percentage sign and an at sign 12 RemoDAQ 8054 User s Manual The delimiter character is followed by a two character address hexadecimal that specifies the target module The actual two character command follows the address Depending on the command an optional data segment follows the command string An optional two character checksum may be appended to the total string Every command is terminated by a carriage return cr Calculate Checksum 1 Calculate ASCII sum of all characters of command or response string except the character return cr 2 Mask the sum of string with Offh Example Command string 012 cr Sum of string 0 1 2 24h 30h 3 1h 32h B7h The checksum is B7h and CHK B7 Command string with checksum 012B7 cr Response string 01200600 cr Sum of string
