The 485SDA10 is a general purpose control module which

operates through an RS-485 interface.  The 485SDA10 offers 11
channels of 10-bit A/D (analog to digital), 3 digital inputs and 3 digital
outputs.  With these features, the module can be used to sense a
variety of external conditions and to control a variety of devices.

The 11 A/D channels allow you to measure voltages from 0 to 5

Volts.  The 3 digital inputs and 3 digital outputs are CMOS/TTL
compatible. The A/D and digital I/O lines are available through a DB-
25S (female) connector.

The 485SDA10 connects to the host computer’s RS-485 or

RS-422 serial port using terminal blocks.  The address and turn-
around delays are software programmable to allow use of multiple
devices or connection to existing systems.  The unit automatically
detects baud rates from 1200 to 9600.  A data format of 8 data bits,
1 stop bit and no parity is used.

Configuration parameters are stored in non-volatile memory.

The configuration parameters consist of the module address,
communication turn-around delay, and digital output power-up
states.
