Thruster SI-MCT01 SI-MCT01 Thruster Control Introduction This document details the telemetry specification for the SI-MCT01 Thruster. Node Configuration The network of nodes uses a Master/Slave configuration. The controller Input being the master and all other nodes are slaves. The master node initiates communication and the slave will then reply. -

Thruster SI-MCT01 Control Notes The commands are in standard ASCII format, 1 Start, 8 Data, 1 Stop, 0 Parity, user selectable Baud Rate {57600 default) and the terminating character ‘\r’ is a single carriage return. To set either a new address or baud rate eeprom write must be enabled. The new address or baud rate will not take effect until the node is reset. - Page 15 Thruster SI-MCT01 Thrust Direction due to Demand The following diagram shows the direction of thruster travel depending on the demand given.
