Five Simple Checks
If you are experiencing a problem with your SAILOR 700 VSAT system, first check
the five simple things below. If these checks do not lead you to the problem,
contact a Thrane & Thrane-authorized technician (see
“Technical Support” on
page 66 ).
Are all lights on the ACU and VMU lit green?
There are three status lights on the front panel of the ACU and one status light on
the VMU. If any of these lights are not lit green, see
“Control Unit (ACU) Status
Lights” on page 44 and “Modem (VMU) Status Light” on page 46 for failure
indications.
Are any error messages displayed on the control panel?
If the control panel is showing an error message, see “Error Messages” on page 47
for error definitions.
Can the ADU find the satellite?
If the ADU is continuously searching for the satellite, check the area around the
ADU for blockage. The ADU needs an unobstructed view of the sky to receive
satellite signals. Common causes of blockage include trees, buildings, bridges,
mountains, and nearby equipment or structures on the vessel. You can find which
direction the ADU is pointing by viewing the “AZ/EL” status on the ACU; see
“Antenna Status Messages” on page 62 . If there is no blockage, and the ADU can’t
find the satellite after 20 minutes, try disabling the DVB-Assist search mode (see
“Setting DVB-Assist Search Mode On/Off” on page 27 ). If the ADU is still unable to
find the satellite, you might be located outside of the mini-VSAT Broadband service
coverage area (the latest coverage information is available at
www.thrane.com ).
Are all system components powered on and connected properly?
Make sure power is applied to all system components, including the VMU, ACU and
switch. Also make sure all of the interconnecting cables are connected tightly.
If you can’t connect via a wireless network, does a wired connection work?
If you have a wireless network onboard, but you are unable to connect to the
Internet while the SAILOR 700 VSAT system is online, connect your computer
directly to the switch via a straight-through (not crossover) Ethernet cable, then
restart your computer. If you can then access the Internet, there is a problem with
your wireless network.
