The U-X1 a very flexible AC power control device that can be used to control the AC power anywhere in the world. Control can be initiated LOCALLY (through the RS-232 or USB port of a PC) or REMOTELY using the built in Ring Count RESET Trigger or any of the optional CPS Remote Controllers (Touch Tone, IP or Cell Controllers). Up to 99 U-X1s can be daisy chained, using standard six-wire phone cable, up to 1500' apart and controlled from one control source locally or remotely.

Additionally, software is available that can automatically RESET the host server or the network equipment (modems routers, gateways, etc.). This is accomplished by running the software on a Windows based server and allowing that server to send a RESET command (through the USB port) to the U-X1 based on failed ping responses or a failed Heartbeat signal from the server itself (hung). This may also be embedded into your application programs.

Each U-X1 supports input AC voltages from 110VAC to 250VAC. It uses internationally standard IEC320 AC connectors. This combination allows it to be used anywhere in the world with locally available power cords. Various AC power cords as well as a Universal Adapter that provides connections for any type of AC Plug in the world are also available. Be sure to order the appropriate power cords separately or supply your own.
See Below.

The U-X1 has one Input IEC320-C13 AC Jack and one "Controlled" IEC320-C14 Output AC jack along with a 15 Amp circuit breaker. The back panel also has a manual control push button switch. It can also be wired to operate remotely up to 3000' away with the Remote Push Button option.

The front panel supports three multi-function connectors. A USB connector and two RJ-11 connectors, any of which can be used to configure the unit or to send the ON/OFF/RESET power control commands locally depending on the application. The RJ-11s also provide the connection for a standard telephone line for remote control and they are also used for the RS-232 and Upstream Downstream connections as well as to connect other external CPS controllers or Base Units.

The operating parameters can also be changed to meet various requirements. The, reset delay time power ON delay, power up state, ring count etc... These preferences are normally entered through the USB or serial ports with simple ASCII commands from a PC.


*PD5 Would change the power restoral time to 15 min.
*PR2 would change the OFF time for a RESET to 20 seconds.
See instructions for a complete list. Once the setup preferences are defined, any ON/OFF/RESET command or manual power ON/OFF will be executed accordingly. You can also make inquires as to the setup preferences. They are confirmed by local on screen replies or audible "beeps" over the phone line if using a TelCo Controller.

Local Control from a PC is provided through a USB port or the Serial/TelCo port (adapter required). The local PC can send simple ON/OFF/RESET Commands to the desired AC Jacks on a single unit or all of the units in a daisy chain. See Command Examples below.

Remote Control over a standard telephone line is provided through the Ring Count RESET feature (standard). This feature simply counts the rings and RESETS once the ring threshold is reached. Other internal and external Remote Controllers are also available. Scroll down.

Our new (optional) Internal Touch Tone Option (ITTO) is also available. It provides direct touch tone control from any standard land or cell based phone. It has a multi-level password and allows the ON/OFF/RESET commands as well as inquires to be sent using any land or cell based phone. It can also share the line with other devices and allows some of the set up preferences to be changed as well. The commands may also be appended to a modem's AT dial string for more automated entry, even though there is no modem at the U-X1 end. Multiple ITTOs/U-X1s may also be connected to the same phone line. If you are considering direct touch tone control, do consider this really neat option.

External Remote Controllers are also available to provide additional methods of remote access.
Touch-Tone Controller (SP-RRC), is used when sharing the TelCo line with a modem or to control an entire daisy chain of U-X1s without the ITTO option.
Multi-Port Controller (MP-RRC), is use to connect several UX-1s in multiple daisy chains (3 or 8 port models), and control them with Touch-tones.
IP Controller (N-RRC), use for remote control over the Internet or any TCP/IP network.
Other controllers are also available, but these are the more popular.

Automatic control
Control with FREE Automatic Software Control utilities that run on a local PC (Windows OS and a USB or serial port is required).

Auto Ping is used to RESET network equipment (modems, routers, gateways, firewalls etc.). It pings outside addresses through the target devices and RESETS them if the return pings are not detected. You can assign two IP addresses for each ping device.

Heartbeat is used to monitor the server, connected to the USB or RS-232 serial port on the U-X1. It will RESET one AC JACK on the U-X1 if serial transmission from the server is not detected within a prescribed time. A DLL is also available to help incorporate the heartbeat into your application if required.

You can use any of these methods as your primary method of control and one or more of the others as backup. As an example, use the Heartbeat software to automatically reset the server and the telephone line touch tone or Ring Reboot feature to turn the server ON or OFF or force a RESET from a remote location.

Or use the External IP Controller (N-RRC) as your primary method of AC power control, but when the network equipment is down, you can rely on the Auto Ping to automatically reset it or use the "out of band" touch-tone option or Ring count RESET feature to reset the Router modem etc.

AC Power Command Examples
These examples are presented to provide a feel for the simplicity as to what is required to send an AC Power Command via: a Serial (RS-232/USB) Port, External Controller, Modem or the Internal Touch Tone Controller (ITTO).

A typical serial port command to RESET POWER on Box #2:     *013
Where "*" is the attention code, "01" is the box address and "3" is the "Action Command" ("1" = ON, "2" = OFF and "3" = RESET). Use "Hyper Term" or other terminal emulation programs to send these ASCII commands.

If this were sent as a touch-tone command through an External Telephone Line Controller, it would be preceded with the controller #, Password (up to six numbers), and the Port number of the Controller (multi-port units) that the UX-1 is attached to:

# 8 Password Port 013#

This could also be sent from a modem by appending it to the AT dial string. Even though there may not be a modem at the UX-1 end.

ATDT 7709450643@ # 8 Password Port 013#

Wild card and Global Commands are also available.

*PON this "global Command" will turn ON one or all of the units in a daisy chain according to the delays applied in the setup
*POF will turn them all OFF
*##1 This "wild card Command" (#) will Turn ON the power on all of the boxes in a daisy chain. The wild card can be used in any or all positions.
To send this command via Touch-Tones to the Internal Controller (ITTO) enter
# Password # "bb" #013.

The Manual ON/OFF Switch can also be used to power the UX-1 ON or OFF. It will power ON according to the preferences that you selected.


In installations where the U-X1 may not be easily accessible for manual control, the manual push button can be extended up to 3,000 feet with the Remote Push Button option. With this option, the U-X1 is supplied with a 6 foot 2-wire cable. The user can splice into the 2-wire cable and extend it up to 3000' or greater, using most any type of wire.

A serial commands allows the selection of the standard "alternating ON/OFF" sequence or the "press once = ON, twice = OFF" sequence. Holding the button for 4 seconds performs a RESET.  The U-X1s should not be daisy chained with this option.
