Other wireless connection problems
Try again a few times. The issue could be related to transient heavy network traffic.
Some network channels may be transmitting a lot of data (like videos, for example),
causing communication to time out.
Wireless networking turned off? If you are attempting to connect over wireless, be
sure it is enabled in the software. The display will show a wireless network symbol (
) when enabled. If wireless networking needs to be enabled, connect with a wired
network connection and enable it.
Computer or mobile device connected to the instrument network? If using wireless,
be sure you have connected your PC to the instrument's Wi-Fi network before con-
necting in the web browser.
Too many devices in a confined space? We have experienced wireless connection
issues when several wireless devices are close together. Move your instrument to a
different room or another place where there are fewer wireless devices.
Wireless antenna unplugged? The wireless antenna is adhered to the internal plastic
electronics shroud. It has a very small connector that plugs into the circuit board.
Power off the instrument, remove the cover screws, and lift the cover slightly to see
if the antenna is attached to the connector on the circuit board. The connector is
near the lower left corner of the processor. If it is unplugged from the circuit board,
reattach it and try to connect again.
See Figure B-3 on page B-5.
Unable to connect with the instrument over a wired connection
Network cable disconnected? Check both ends to be sure it is connected to the
instrument and to your computer or network.
Instrument on a different network than PC? If you are using an Ethernet cable, be
sure the instrument network cable and your PC network cable are connected to the
same local network.
Network not detected by the instrument? Check the IP address given on the instru-
ment display. If the display says IP:down, the instrument is not detecting a suitable
network (the network cable may be unplugged, network switch or routers may be
powered off, the IP address setting in the instrument may be incompatible with the
network or computer).
