Serial 24 channel digital i/o card, use w/basic stamp
* Multiple 24BDIO's can communicate on a single serial line using different adresses.
* Simple interface with discrete devices.
* Reads 24 bits of TTL level digital inputs.
* Writes 24 bits of TTL level digital outputs.
* The serial connection is a simple two wire serial interface.
* The serial communication is true TTL at baud rate of 2400 bps, no parity bit, eight data bits, and one stop bit (2400N81).
* The operating mode is user selectable via dipswitch.
* software-selectable user interface modes allow the user to communicate with the 24BDIO using either hex or ASCII for the data values.
The 24BDIO (24 Bit Discrete I/O Card) provides a simple interface to discrete devices. Communicating to the 24BDIO serially, in input mode, reads 24 bits of TTL level digital inputs or, in output mode, writes 24 bits of TTL level digital outputs. The serial connection is a simple two wire serial interface. The serial communication is true TTL at baud rate of 2400 bps, no parity bit, eight data bits, and one stop bit (2400N81). The operating mode is user selectable via dipswitch. The input mode allows reading each of 24 bits as inputs. The output mode allows control of each of the 24 bits of the 24BDIO via three bytes of serial data in hex mode, and via nine bytes in ASCII mode. The software-selectable user interface modes allow the user to communicate with the 24BDIO using either hex or ASCII for the data values. This unit is well suited for use with microcontrollers or basic stamps. You will need an RS232 to TTL converter (like our PM232) to use the 24BDIO with a computer. See the datasheet for examples and sample code.Multiple 24BDIO's can be used on a single serial port. Up to 8 24BDIO's set for input and 8 more set for output can share the same port. There are additional modules available that can share the serial port as well.
A software utility for test of this item is available on our website http:// /popup_24BDIOutility.html when coupled with a PM232.
