Overview
The SDM-SIO1 is an RS-232, RS-422, or RS-485 serial expansion module. Up to fifteen SDM-SIO1 modules may be connected to a single data logger SDM interface. This module is commonly used to interface serial sensors to a data logger. Please refer to the Compatibility information regarding which data loggers the SDM-SIO1 may be used with.
Technical Description
The SDM-SIO1 is a serial expansion module that allows a data logger to communicate with serial devices that interface using true RS-232, RS-422, or RS-485 signals. Up to fifteen SDM-SIO1 modules may be connected to a single data logger SDM interface. Remote serial devices use industry standard hardware and protocols to connect to the data logger through the SDM-SIO1 interface. When operating in the RS-232 mode, the module also provides hardware handshaking. The SDM-SIO1 Module is implemented in such a way that it looks like a built-in serial port to the user when writing programs in CRBasic. This means that all the user needs to do is define the address of the SDM-SIO1, using a rotary switch on the side of the unit. The serial port can then be used as if it were built into the data logger.
