Problems Communicating With RF Network Devices
If the 2435 is not communicating with other devices in the RF network, check these
possible problems.
Problem Solution
When you turn on the terminal after it was
suspended for 10-15 minutes or longer, the
terminal can no longer send or receive
messages over the network.
The host may have deactivated or lost your current terminal emulation
session. In a TCP/IP direct connect network, you need to turn off the
“Keep Alive” message (if possible) from the host so that the TCP
session is maintained while a terminal is suspended.
The Network Connect icon is off. The 2435 is
not communicating with the access point.
Make sure the access point is turned on and operating. You may also be
using the terminal out of range of an access point. Try moving closer to
an access point to re-establish communications.
Make sure the Network Activate command is enabled. For help, see
“Network Activate” in Chapter 6 of the 2400 Family system manual.
Make sure the 2435 is configured correctly for your network. In an
OpenAir network, the domain and the security ID on the terminal must
match the values set for all access points the terminal may
communicate with. In an 802.11b network, the network name on the
terminal must match the values set for all access points the terminal
may communicate with. For help, see “Using RF Communications on
the Terminal” in Chapter 3.
In a TCP/IP direct connect network, you cannot scan or enter data when
the 2435 is not communicating with an access point or you may lose
your TCP session.
If you are within range of an access point, the Network Activate
command is enabled, and the Network Connect icon is still off, you
may have a defective radio card. For help, contact your local Intermec
service representative.
The Network Connect icon blinks on the
terminal screen.
In a UDP Plus network, the terminal is communicating with an access
point, but it is not connected to the DCS 30X. You may need to check
the 2435 configuration or make sure the DCS 30X is running and that
data collection is started.
The 2435 may be out of range of an access point or the access point
may have recently been turned off. Make sure the access point is still
turned on and the 2435 is with in range.
Each device in the network must have a valid IP address. The IP
addresses set on the terminal must match the addresses configured on
the DCS 30X or host. For help, see “Using RF Communications on the
Terminal” in Chapter 3.
