RS-232 DATA ACQUISITION MODULE 232SDA12 PRODUCT FEATURES • Automatic Baud Rate Detection • 11 Channels of 12-bit A/D • 0.61OmV A/D Resolution with 2.5VDC Reference • 3 Digital AInputs -30 to +30 VDC • 3 Digital Outputs 0 to 5 VDC The 232SDA12 provides a low-cost, easy to use solution for serial port data acquisition. It offers 11 channels of 12-bit A/D inputs, 3 digital outputs, and 3 digital inputs. With these features, the module can be used to sense a variety of external conditions and to control a variety of devices. The module comes with a demo program in QuickBasic. A data logging utility is included to provide a simple way to import data into other programs such as Excel . These programs are Widows compatible 95, 98, NT, 2K, XP, and Vista . RS-485 and 10-bit A/D versions are available 232SDA10, 485SDA10, and 485SDA12 . Operation • A manual is contained on the CD ROM which ships with the module. •There are only three commands required to control the 232SDA12 Read A/D, Read Digital I/O, and Set Output State. Bit error detection is also possible. Refer to the manual for information concerning these commands. •A/D Converter The module has 11 channels of 12-bit A/D inputs. The full-scale voltage can be set anywhere from VDC to VDC. A 5 VDC reference is available to provide a 0 to 5 VDC range without any external components. The A/D converter has a conversion time of approximately 10 microseconds. However, the sampling rate is limited by the serial communications. The actual sampling rage for a single channel is approximately 120 samples per second at 9600 baud. This rate drops to 25 samples per second when sampling all of the channels. The A/D inputs are made via a DB-25 female connector. • Digital I/O Lines The 232SDA12 has 3 digital inputs and 3 digital outputs. The digital outputs are CMOS/TTL compatible. The digital inputs are CMOS/TTL compatible and can handle voltages from -30 to +30 VDC. A DB-25 female connector is used. •Digital I/O Lines The 232SDA12 has 3 digital inputs and 3 digital outputs. The digital outputs are CMOS/TTL compatible. The digital inputs are CMOS/TTL compatible and can handle voltages from -30 to +30 VDC. A DB-25 female connector is used. •Communications Connect the unit to your PC. The baud rates between 1200 and 9600 are automatically detected. Format is 8 data bits, 1 stop bit, and no parity. The 232SDA12 is a DCE device. Refer to the product manual for more information.
