GENERAL DESCRIPTION and TYPICAL APPLICATIONS:
The AV10R features ten relay outputs that can be controlled
through the RS232 serial port of a PC or other host computer.The AV10R communicates
on RS232 at 9600 N,8,1 baud and is non-addressable. With this format, the unit
is "always on" but only one board can be on a serial line.
Easy to use commands give full control of the boards
functions. Two levels of pre-timers allow adjustments to the main timer intervals
from 10ms to 650.25sec for an effective relay timer range of 10ms to 45+ hours,
plus on and off.
Easy connections are possible with screw type connectors
for the I/O, a barrel connector for power and a phone style RJ11/12 connector
for communications.
The AV10R has an onboard switching regulator for 9-35VDC
operation, LED indicators for transmit and receive status for the serial communications.
13 jumpers are available for flow control, optional inputs and in-circuit programming.
Originally designed for use with model trains, the unit
can be used to switch anything within the range of the relays, which are rated
for 1.0A @ 30VDC.
Available from R.E.Smith is a free program that facilitates
serial communications testing.
