Reset Button
A reset button is located on the front panel to restart the CXCM4 microprocessor. The display reappears approxi-
mately 15 seconds after pressing the reset button. Refer to the software manual for more information.
NOTE:
Always select the shutdown menu item on the LCD before pressing the reset button.
Ethernet Port
The RJ-45 jack and a standard network cable can be used to connect the CXCM4 to a user supplied network
(TCP/IP secured by user) .
Local access (e.g. with a laptop computer) is also possible from the Ethernet port using a standard network
crossover cable.
RS-232 Serial (Craft) Port
Local access to the CXCM4 is possible through the front panel RS-232 serial port with a null modem cable. The
communication protocol also supports a web interface (Microsoft Internet Explorer 7 or greater). The remote
screen display is an enhanced version of the CXC front panel display.
