Bulletin 639519 • Revision D May 2009 7-3
7.12 Antenna Movement Failed
• Test the actuator in isolation – See Section 5.
7.13 “Device, S/N Rejected, Unable To Control, Skipping…”
• Background:Insufficient information from actuator for controller to control device (garbled
message) caused by noise on line, fi rmware download to actuator failure, or old software (Version
5 or earlier).
• Power cycle controller.
• Update controller software.
• Update fi rmware on actuator.
• By-pass TMA to make sure TMA is not interfering with communication.
7.14 Intermittent Error: “FT_purge I/O Error”
• Probably controller malfunction. Verify by substituting another controller.
7.15 Unable To Get Screen Shot
• On laptop, press Alt + Prtscn. (If Prtscn key is the same color as Fn key, press Fn + Alt + Prtscn.)
Screen shot goes to clipboard without notifi cation. Open Word and paste (Cntl V). Screen shot
will paste into the Word window.
7.16 Unable To Operate Controller Using Serial Cable
Connecting To A Com Port:
• The ATC200-LITE-USB allows connection through com ports 1 through 8. If no such com port is
available, free a port between 1 and 8 for usage by ATC200-LITE-USB. The basic idea is to reas-
sign something using a port between 1 and 8 to a new port setting so that its former port is free
for ATC200-LITE-USB.
• On Windows XP (classical view) go to Start→Settings→Control Panel→System→Hardware
Tab→Device Manager→Ports.
• On Vista, go to Start→Control Panel→System→Device Manager (under Tasks on left panel)→Ports
(Com & LPT).
• We need to free up a communications port numbered less than 8 that can be used by ATC200-
LITE-USB. For example, choose port 6. Right click on port 6. Go to Properties→Port Settings
tab. Click Advanced.
Note: Blue Tooth ports cannot be used. Port settings tab does not appear for Blue
Tooth ports, which are not communications ports.
• Click on arrow for drop down menu of Com Ports. Select a free com port with number greater
than 8. For instance, choose 13. Now the device formerly on 6 will be on 13. Com 6 can now be
used by ATC-200-LITE-USB. If no ports are available, see your IT department.
