Maintain and Troubleshoot the MobileView Terminal and IP65 Junction Box Chapter 6
Real-time Clock Battery The MobileView 2711T terminal uses nonvolatile memory that requires a
real-time clock (RTC) lithium battery to retain system information when power
is removed. The battery has a 17-year life.
The RTC battery is soldered to the main circuit board, non-serviceable, and
therefore not intended to be replaced during the life of the MobileView 2711T
terminal.
Troubleshoot the
MobileView 2711T Terminal The following table lists possible anomalies that can occur with your terminal
and solutions to the anomalies.
Anomaly Solution Page
Terminal does not power up Check for 24V DC power on the connector of the MobileView junction box.
• For 2711T-JBIP20DC, the IP20 junction box: Check the terminal connections at X1 and X2 of the junction
box.
• For 2711T-JBIP65DC1, the IP65 junction box with cord grip connections: Check the power connections
at the S16 terminal of the junction box.
• For 2711T-JBIP65DM1, the IP65 junction box with M12 On-Machine™ connections: Check for a solid
connection between the power supply cable and the cable connection on the junction box.

Check the terminal connections to the main control board of the MobileView 2711T terminal. 24
Terminal screen is dim or black If the screen is readable:
a. Adjust the screen brightness at the bottom of the window that appears.
a. From the MobileView terminal desktop, tap Power Options.
30, 56
If the screen is black:
• Tap the touch screen or any of the keypad buttons to de-activate the screen saver.
• Check power to the terminal. Follow instructions for anomaly, ‘Terminal does not power up.’
• If the screen is blinking or rapidly changing brightness, a corrupted registry or OS image can exist.
a. Restore the OS image.
b. If an OS image restoration does not correct the anomaly, contact Rockwell Automation® Technical
Support.

Difficulty with touch screen selections The touch screen can be out of alignment. Recalibrate the touch screen. 74
Terminal screen is static (locked up).
Touch screen and keypad activations do not initiate any
changes. Check Ethernet communications. See the next anomaly, ‘Terminal does not communicate on Ethernet
network.’
Terminal does not communicate on Ethernet network Check Ethernet cable connections at the MobileView junction box and your Ethernet hub.

Try to ping the MobileView 2711T terminal from a personal computer in your network to check for correct
configuration settings, then check MobileView 2711T terminal settings. 72
If you are using a DHCP server, check if the DHCP function is set in the network settings of the MobileView
2711T terminal. 73
If you connect to the Ethernet network with fixed settings, verify that the IP address, subnet mask, and
default Gateway-network settings are correct in the MobileView 2711T terminal. 73
Check the Ethernet connection on the MobileView 2711T terminal. 24, 28, 29
Program memory low From the terminal desktop, tap File Explorer. Use File Explorer to clean up or delete unnecessary files. 56
An error message alerts you to install Windows Power to the MobileView terminal was temporarily interrupted during the Windows setup process. Restore
the OS image with an image file downloaded from the Rockwell Automation PCDC site. 83
The Windows OS image is corrupt Restore the OS image from a backed up image or with an image file downloaded from the Rockwell
Automation PCDC site. 80, 83
