TM 785 Time Clock

Sierra's TimeMaster TM 785 time clock





Sierra Workforce Solution’s TM785 time clock can be programmed to prompt employees for data input, display employee messages, validate job costing entries, restrict employee punching via a schedule, regulate employee access to restricted areas, control a bell and much more. Communication between the TM785 and your computer is accomplished by one of Sierra’s automatic polling and programming utilities or integrated time and attendance systems.

The TM785 time clock assures accurate, reliable input. Employees simply enter information through the TM 785’s keypad, by swiping a magnetic stripe, bar code, or proximity badge. In addition, the TM785’s biometric capability supports multiple types of fingerprint sensors. Employee feedback is provided through audible accept/reject tones and displayed messages. The TM785 automatically transfers data to your computer. In turn, the computer is used to program the TM785.

Each of the TM785 time clock’s function keys can be programmed to ask up to four levels of information. Each piece of information can be validated and stored in the terminal’s memory until requested by the host computer. The TM785 can be programmed to prompt employees for data input, display employee messages, validate job costing entries, restrict employee punching via a schedule, regulate employee access to restricted areas, control a bell and much more. The TM785 collects this data and transfers it to your computer via RS232 serial, RS485 LAN or Ethernet communications, whether wired or wireless.

Sierra Workforce Solutions has over 32 years of time and attendance industry excellence providing in-depth business requirements analysis, best practice consultation and guidance, professional implementation and training.

Ethernet Communications: With the optional internal Ethernet card, the terminal can connected to any 10/100 Ethernet network

Baud Wi-Fi Wireless Communications: The TM785’s wireless card allows the 780 to communicate over a standard 802.11b network. The wireless network must be configured with an IP address, gateway, subnet, and WEP key (if available).

P.O.E (Power over Ethernet): The TM785’s has the optional capability of drawing it’s power from the Ethernet communications line (Ethernet line must support POE) This eliminates the need for high voltage power at the terminal location.

Biometric Fingerprint Reader: The TM785 time clock can store up to 9,000 biometric fingerprint templates for verification (1 to 1) or identification (1 to many). The terminal utilizes a High resolution 500 dpi finger template. Sensor options include Optical, or Capacitive.

External Reader: The TM785’s has two reader ports to connect external devices such as a Bar Code gun or an Access Control Swipe Reader that could be mounted outside a door.

Front Panel This Time Clock has the following front panel features: 1. A 32 character LCD with a back light display is located in the upper part of the front panel.

2. Two arrow keys are located to the right of the display panel for line up and line down maneuvering.

3. Function keys located on the left, below the display.

[IN], [OUT], [F1], [F2], [F3], [F4], [F5] and [F6].

4. A numerical keyboard of fourteen keys, including [Enter], [Back Space], [Dot] and [Clear].

5. The Alarm light “!”, is located to the left of the display. The alarm light is an LED that lights when at least half of the memory is used; its blinks when the memory is full.

6. The ON button enables a 15 second manual operation window if the terminal is on battery back-up power.  Biometric fingerprint reader of FPU-s or Mv1200 type which supports thousands of fingerprint templates (9000 for FPU-s) for verification and identification.

7. The fingerprint’s drive ring on the right side of the TM785, with the internal badge reader/bar code/proximity located below it.

Bottom Connector Panel

1. Power Supply 2. External secondary Reader 2 3. External secondary Reader 1 4. I2C – I/O Extension (N/A) 5. Network 6. Serial I – Serial port connection for printer (N/A) 7. Host – RS-232 / RS-485

Internal Components 

The TM785 time clock has two back-up battery modules, one for the real time clock memory and the other for operation during a power failure.

Standard memory back-up module is a lithium battery, which will keep the internal clock running and the memory intact, for 30 days during a power failure.

The back-up battery provided (in addition to the standard memory back-up) is a self-recharging system which allows the terminal to operate during a power failure. The battery provides power for one and a half net hours of use. A shut down timeout feature enables the terminal to operate for more extended periods of time.  During a power failure, the user presses the battery key to activate the terminal. Data can then be entered and stored in the terminal memory. The time-out will cause the terminal to shut down automatically after the last use of the terminal, until the battery key is pressed again.
