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 datalogger SDM interface. This module is commonly used to interface serial sensors to a datalogger. Please refer to the Compatibility information regarding which dataloggers the SDM-SIO1 may be used with.

Detailed 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.

Additional Compatibility Information
Data Logger Considerations
The SDM-SIO1A does NOT support auto baud rate detection nor the use of the serial port for general PakBus communications.
Enclosure Considerations
The SDM-SIO1 requires a desiccated, non-condensing environment. The SDM-SIO1 has built-in keyhole flanges for mounting to the backplates of Campbell Scientific enclosures.
