Mounts as a COM Port

This Taralist controller connects to the RS-232 port of your computer and will mount as a COM port on your PC.  Using a simple USB to Serial Adapter allows you to use RS-232 devices with ease.  This combination is actually better than using a device with a onboard USB port, because it eliminates most of your EMI problems while maintaining compatibility with today's computers.

Mounts as a COM Port

This ProXR Lite series controller connects to the RS-232 port of your computer and requires a 12VDC Power Supply.  This ProXR series controller connects to the serial port of your computer and will mount as a COM port on your PC.  Once powered up, the controller waits for a command.  A command consists of a few bytes of data in numerical format usually between 2 and 6 bytes.  Once the command has been received, the controller processes the command, and sends you back ASCII character code 85 to signal the completion of your command.

ZRS ModulesRS-232 Relay ZRS Module

This board is equipped with a ZRS Module.  The ZRS communications module adds RS-232 communications to the board.  The ZRS module is powered from the serial port of your computer.  The board itself will require 12 volts of power and can be hard wired or you can purchase a "wall wart" type transformer at checkout.

Three ZRS Modules Available

There are three RS-232 connection options available for this controller.


ZRS-A
Wire It Up
ZRS-B
Plug It In
ZRS-AB
Both!

Choose Your Connector

Choose the connection that fits your needs. The ZRS-A connection is recommended for applications where hard wiring directly to the board is needed. ZRS-B has the full 9-Pin DB-9 connector on the board. The ZRS-AB Has the DB-9 connector but is is located off the board for applications where the board may be place inside an enclosure an the RS-232 connector needs to reach to the side of the enclosure.  You can choose one of these connection options at checkout.

Take Manual Control of Taralist

At any time, a computer may monitor the Taralist Controller to read the status of the relays, activate relays, or change configuration settings using Base Station Software.  This USB version will allow access to the board as long as it is still connected to the USB port of your computer.  A computer can take over the Taralist or the Taralist can operate autonomously (without a computer).  The Taralist Configuration Utility is part of Base Station software and this is a free download.

Once Configured

Once the Taralist is configured, it will run through the list of events stored in its on board memory every second to look for a match with the current time.  If a match with the current time and a configured event is discovered, it will execute the event.

Controlling Relays

There are 2 possible ways to control the relays on a Taralist Series controller.

Who's Qualified to Use the Taralist Series?

Some computer skills required.  The Taralist Relays do not require programming, simply configure the device with the included Base Station Software.  While programming is not required and simple functions can be done rather easily with basic computer skills, complex events can be configured which will require some understanding and patience.

Induction Capacitors

Induction CapacitorPerhaps the most overlooked aspect of relay control is proper handling of inductive loads. Inductive loads can best be defined as anything with a magnetic coil, such as a motor, solenoid, or a transformer.  Controlling a inductive load using this relay controller requires the use of induction suppression capacitors.  The purpose of this capacitor is to absorb the high voltages generated by inductive loads, blocking them from the contacts of the relay.  Without this capacitor, the lifespan of the relay will be greatly reduced.  Induction can be so severe that it electrically interferes with the microprocessor logic of our controllers, causing relay banks to shut themselves down unexpectedly.  In the case of USB devices, customers may experience loss of communications until the device is reconnected to the USB port.  Capacitors that we offer are available at checkout, for more information view our Induction Suppression Video.
