General Description:

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.
