6. 031A 33A 34 User s Manual 3 Command Set Introduction To avoid communication conflicts when several devices try to send data at the same time all actions are instigated by the host computer The basic form is a command response protocol with the host initiating the sequence When modules are not transmitting they are in listen mode The host issues a command to a module with a specified address and waits a certain amount of time for the module to respond If no response arrives a timeout aborts the sequence and returns control to the host Changing 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 19 RemoDAQ 8031A 33A 34 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 s
