Overview
The SDM-SIO4 is a legacy product and should be purchased only as a replacement or for use with legacy data loggers such as the CR10X. When considering the purchase of an SDM-SIO4, first consider using the SDM-SIO1 instead. Please note that the SDM-SIO4 is not compatible with all data loggers.
Primarily for legacy data loggers, the SDM-SIO4 adds serial I/O capacity and flexibility. It has four serial ports that communicate with serial sensors, display boards, printers, and other serial devices. After being programmed, the SDM-SIO4 communicates with connected devices in parallel with the data logger's own program sequence.

Benefits
- Provides four configurable serial RS-232 ports
- A multitasking operating system allows concurrent transmission and receipt of data on all ports.
Specifications
- Communication Rate
- Speed at which data is transferred is controlled by the data logger and can vary with the microprocessor activity as well as the length of the SDM cables.
- Typical Transfer Rate
- One byte per millisecond
- Power Supply
- Unregulated 12 V supply, 9 to 18 Vdc
- Internal Battery
- Retains configuration information only.
(Lithium battery has an estimated life of 10 years.)
- Number of Ports
- 4
(independently configurable for different serial data formats)
- Serial Ports Baud Rate
- 25 to 115,200 bps
- Port Output
- 0 to 5 V logic
- Port Output
- ±5 V for RS-232
(switchable)
- Port Configuration
- 9-pin D connectors
- Data Flow Control
- By data logger or SDM-SIO4, if required, using hardware or software protocols
- Onboard Diagnostics
- Built-in system watchdog resets the processor in the event of a crash caused by transients and a built-in LED gives an indication of SDM-SIO4 status on power-up.
- Input Voltage Limits
- ±25 V
- Operating Temperature Range
- -25° to +50°C
- Dimensions
- 18.3 x 8.9 x 3.6 cm
(7.2 x 3.5 x 1.4 in.)
- Dimensions
- 22.4 x 8.9 x 3.6 cm
(8.8 x 3.5 x 1.4 in.) with mounts
- Weight
- 499 g
(1.1 lb)
Current Drain
- All Ports Active
- 40 mA
- Quiescent
- 0.7 mA
(quiescent state entered if there is no SDM or port activity for ~30 ms)
Buffers (each port)
- Type
- Fill & stop
(Once filled, additional data received is lost.)
- Receive (Rx)
- 981 bytes + 16-byte hardware buffer
- Transmit (Tx)
- 981 bytes + 16-byte hardware buffer
- Processed Data Storage
- 891 bytes
(suitable for storing 224 4-byte Campbell Scientific floating point values)
- Floating Point Buffer
- Used only when the data logger outputs floating point data via the SDM.
This buffer is 241 bytes—sufficient for 60 floating-point values.
