Q u i c k R e f e r e n c e Introduction The VRC 6940 is a rugged computer terminal that can be installed in a vehicle or mounted on a wall or workbench. It allows you to gather information quickly, easily and accurately using the keyboard or an attached scanner. The VRC 6940 transfers the information to a base station Access Point (AP) through a Symbol Spectrum24® radio network. Then the AP transmits that information to a host computer for processing.

Q u i c k R e f e r e n c e Optional Accessories You can order these optional accessories from Symbol: • • • • • • • Scanner cable RS-232 cable Primary antenna Vehicle-mounted antenna Spectrum24 PCMCIA radio card AC universal power supply AC cable. Basic Operation Turning the Terminal On 1. Press the ON/OFF key located at the top right corner of the alpha section of the keyboard. ON/OFF key CTRL key 2.
V R C 6 9 4 0 T e r m i n a l Turning the Terminal Off In normal operation, you will not turn the terminal off: you will place it into suspend. The terminal only turns off if you have: • • disconnected the power cable, AND allowed the internal battery to run down. For more information, see Charging the Internal Battery on page 6. Modifier Keys: SHIFT, FUNC and CTRL SHIFT, FUNC, and CTRL are modifier keys that you can use to generate a special character or function (see Basic Operation on page 3).
Q u i c k R e f e r e n c e The terminal restarts and you can log in to an application. If you have problems opening an application after resetting the terminal, contact your System Administrator. Note: If you reset a terminal, you may lose any unsaved data. Entering Data You can enter data into a VRC 6940 terminal by using the keyboard or an attached scanner. Tips for Using the Keyboard • • • • Press only one key at a time. Pressing two or more keys at the same time can cause an error.

For information on using the scanner, consult the documentation that came with the scanner. Charging the Internal Battery The VRC 6940 has an internal battery that provides power and saves your session if there is a temporary fluctuation, disconnection, or interruption in the unit’s main power supply. The internal battery recharges itself from the terminal’s main power supply.
Q u i c k Note: R e f e r e n c e If you unplug the power cable, and the internal battery is not charged, the terminal may shut off. Troubleshooting Problem Action The terminal will not start. Make sure that the terminal is connected to a power source. If the external power cable has come unplugged, plug it back in and press the ON/OFF key to restart the terminal. If the internal battery was charged, the terminal will maintain your session until you reconnect it to the power source and restart it.
V R C 6 9 4 0 T e r m i n a l Problem Action Power fault. This message may appear if the terminal’s last shutdown was caused by power failure. A power failure can be caused by: • removing the terminal from the power source • removing the vehicle battery • sudden main battery failure If the internal battery is charged, it can maintain session data for up to 72 hours. You can replace the main power supply and restart the terminal without losing data.
Q u i c k R e f e r e n c e Equipment Required Vehicle Mounting • • • • • • • VRC 6940 terminal. an External DC power cable (supplied with terminal). minimum of two 3/8” bolts with self-locking nylon nuts. a drill with a 7/16” drill bit. 7/16” hex wrench. a connector for terminating the External DC power cable. Select one that mates with your vehicle’s power supply. primary or external antenna (optional). Wall or Workbench Mounting • • • • • • • • VRC 6940 terminal.
V R C 6 9 4 0 T e r m i n a l To install VRC 6940 hardware: 1. Prepare a mounting location: a. Select a location to mount the terminal. The terminal’s attached bracket has holes cut for bolts. Use these holes to mark bolt hole locations. b. Prepare the mounting surface to accept two 3/8” bolts. Drill two holes with a 7/16” drill bit.

When you first unpack it, the terminal has hex bolts in place of the Bracket Knobs.These knobs allow users to adjust the angle of the terminal. a. Use a 7/16” hex wrench to remove the bolts and replace them with the Bracket Knobs.
V R C 6 9 4 0 T e r m i n a l b. To adjust the angle of the display, partially unscrew the Bracket Knobs. Then adjust the angle of the terminal and re-tighten them. 4. Optional: attach a primary antenna to the connector at the top of the terminal. To attach the antenna: a. Place the metal end of the antenna onto the connector. b. Line the posts up with the connector and press down. c. Twist the bottom ring clockwise to lock it into position. Antenna Connector Back of Terminal 5.
Q u i c k R e f e r e n c e b. Connect one end of a coaxial cable to the terminal’s Antenna Connector. Connect the other end to the vehiclemounted antenna. Make the coaxial cable as short as possible to minimize signal loss. Providing Power: Vehicle Installations VRC 6940 terminals can be powered by: • • 12V or 24V gas-powered vehicles battery-powered vehicles, up to 60 volts To provide power to a vehicle-installed VRC 6940: 1. Locate your vehicle’s power source.
V R C 6 9 4 0 T e r m i n a l To prepare the end of the External DC power cable: a. In-line fuse holder: if no fused output is available, add a fuse-holder and 5 Amp fuse to the External DC power cable: i. Strip back six inches of the cable jacket. ii. Cut about 5” from the red power wire and strip 3/8” insulation from the wire. iii. Strip 3/8” insulation from the fuse-holder wire. iv. Twist the stripped wire ends together and splice them using a twist-on nylon wire connector. v.
Q u i c k R e f e r e n c e b. Route the External DC power cable from the terminal location to the connection point for your vehicle’s power source. ! Installation Note: Cable Routing Caution ! The means of routing and securing the External DC power cable from the terminal to the vehicle power source is extremely important. Hazards associated with improper wiring can be severe.
V R C 6 9 4 0 T e r m i n a l WARNING A Lead Acid battery can leak Hydrogen gas. A spark anywhere near the battery can cause it to explode. Always make your final connection to power as far away from the battery as possible, i.e., connect the power cable to the battery first, then connect it to the terminal.
Q u i c k R e f e r e n c e It takes 48 hours to fully charge the internal battery. A fully charged internal battery maintains data for up to 72 hours if the unit is disconnected from its main power source. This time is reduced if the radio is in a mode where it maintains continuous communication with a host.
