Worth Data RF Terminal 7000 - Manual (Page 75)

to the floor is the worst position.
• In an unobstructed outdoor area a range of 3.3 miles or greater “line-of-sight” is possible but indoor
“obstructed” range will be much less. Reflections and obstructions, depending on the density and material,
can reduce the range to a few hundred feet indoors. Far better than typical WiFi systems.
• To accurately determine the hardware required to cover a particular area, you should use the Site Test mode
built into the RF Terminal.
I can't communicate with the RS-232 port on my host CPU...
• This is one of the biggest problems called in. If you are not using our cables, check your cables first. If you have
an extension cable, remove it for testing. If you have an extension cable of 80 feet or more attached to a Windows
host, you need to be sure certain pins are not attached in the DB9 or DB25. See Appendix C; RF Serial Pin-outs.
• If you are using the PICK or UNIX operating systems, be sure you have set the Base Station to be
"XON/XOFF Sensitive". You need to do this to prevent the XOFF code being sent as a "Base Initialization"
message.
• Windows 95,98,2000,ME, NT; COM port setup should also be changed to turn off XON/XOFF. XON/XOFF is
the default for Windows. You set these through the control panel, System, Device Manager, Ports (COM & LPT),
COM Port, Port Settings, Flow Control. Set Flow Control to None.
RF Terminal Problems
When laser is triggered, it cycles power by itself – 1 st screen
When a voice message plays, it cycles power by itself –1 st screen
When I turn it on, it just beeps continually.
When I turn it on, the screen flashes continually.
• If the battery is very low, when turned on, the Terminal will just keep beeping; it is cycling power, over and
over because the batteries are too low.
• If the batteries are at a specific low point, the laser triggering or playing a voice message will be just enough
extra power draw to force the terminal to cycle power.
• Charge your Terminal for at least an hour and try again.
I get 6 beeps when the RF Terminal powers up...
• The unit needs repair. Call Worth Data for an RMA.
Problems reading Bar Codes
The reader won't beep when I try to read bar codes...
• Try reading a known good bar code - try the 1 on the Setup Menu bar pad table. Follow the steps for proper
scanning technique discussed in Appendix M; How to scan a bar code.
• Make sure the reader is configured to read the type of bar code you are trying to scan. Most bar code types are
disabled by default and need to be enabled using the Setup Menu or keypad while in Setup Mode.
I get extra characters at the beginning or end of my bar code data...
• Clear the Preamble and Postamble settings.
