Chapter 1- Introduction
485SDA10 Features
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.
