DLPRO 3000

The DLPRO 3000 Host Console software runs on a host computer, providing the user interface for system configuration, administration and control.

Additional Information


ELTEC’s DLPRO software is the programming platforms for the NTC17E, TC-18, and TC-3000 time clocks. DLPRO provides the user with an intuitive graphic user interface to program and manage multiple schedules and easily download them to each clock using the transfer cable (NTC17E) ,USB interface cable (TC-18), or remote internet connection. The software for the TC-18 and TC-3000 additionally provides an interface to test clock functionality, maintain DST settings, and synchronize the clocks time and date to the host computer.  Each time clock has a different version of DLPRO. The NTC17E uses DLPRO17E, the TC-18 uses DLPRO18, and the TC-3000 uses DLPRO3000.

Network / IP Programmable Time Clock

The programmable SYSTEM 3000 IP addressable time clock for your school zone flashing beacons reduces/eliminates the need to send technicians for updating or modifying school schedules or on-site trouble shooting.

Using your available Internet or private intranet, area Wi-Fi or cellular modem along with RF technology, it provides real-time closed-looped management from a central computer.

The SYSTEM 3000 consists of three items:

  • DLPRO 3000 software
  • LANG 3000 (gateway)
  • TC-3000 time clock.

System communication is established over the network utilizing a secure, IP addressable dedicated port on the host computer and a LANG 3000, positioned anywhere there’s a network connection. The LANG 3000 placement is flexible. For example, it can be placed in an office across town or the state, in an intersection cabinet, or at the school itself (pole cabinet or at school building).

A spread spectrum RF virtual private network (VPN) is created between the LANG 3000 and its associated TC-3000 time clocks.

The SYSTEM 3000 provides immediate 2-way communication with real-time monitoring and control displaying clock and LANG status. With DLPRO 3000 software graphics, information about system performance is displayed. Within seconds of sending commands the system returns a confirmation of message reception. At any time, a single clock, group of clocks or all clocks can be interrogated to verify status.

The LANG 3000 communicates and stores up to six different schedules for up to 20 TC-3000 time clocks per schedule (120 clock capacity per gateway). Each school schedule includes the Monday-Friday (default) schedule, holidays (no school days).

Upgrading and replacing your existing time clock with a TC-3000 is uncomplicated. The dimensions allow plug-and-play replacement of the current clock using the same back panel. Depending on the brand, the cable harness may remain the same.

The system offers automatic problem reporting. Warning or failure email messages are sent to the technicians on call as well as other designated individuals to report low voltage conditions, communication faults or any manual overrides. All annual programs are downloaded into non-volatile memory and are stored in both the LANG 3000 and the TC-3000 time clock. Should there be a system interruption, the flashing beacons continue to operate as scheduled, and of course, an email notification is sent.

Owning DLPRO 3000 software allows full control and independence of your school zone systems for years, eliminating contracts/arrangements for hosting the programs, which avoids exposure/vulnerability.

Over-the-air DLPRO 3000 software updates are provided at no charge.

The TC-3000 time clock has an internal flasher and is equipped with one or two independent output relays.

Both the TC-3000 time clock and LANG 3000 operate on either 120VAC or 12VDC (solar).

The SYSTEM 3000 operates as a stand-alone time based controller, allowing it to be used anywhere a time based relay output controller is required.

The DLPRO 3000 software runs on Windows operating systems (2000, XP, Vista, and 7).
