II. Initial Setup of Communications between the CDM-625 Field Unit and
the User PC
CAUTION: Obey precautions for handling electrostatic-sensitive devices.
A. Connect the custom Serial Adapter Cable between the CDM-625 Field Unit’s ‘ESC’ port and an available
RS-232 serial port on the User PC.
B. Connect a CAT5 Ethernet cable between CDM-625 Ethernet IP Module Port ‘1’ and an available Ethernet
network RJ-45 port on the User PC.
C. Use the terminal emulator program to configure the serial port communication and terminal display
operation as follows:
• Port Flow Control = NONE
• Display New line Rx/Tx: CR
D. Upon successful setup of communications between the User PC and the CDM-625 Field Unit Command
Line Interface (CLI), you will see the CLI command prompt on the terminal emulator display: “->”.
E. Using Windows Command-line (Start > Run... > cmd.exe), create a folder (directory) named “temp” (or
some other easy-to-remember name) on the User PC for placement of the CLI, modem, and IP Packet
Processor data collection files:
Example: C:\>md temp
F. Set the terminal emulator program to capture the CLI session to a text file. Be sure to specify your “temp”
folder as the path for the file that will be created.
Refer to your terminal emulator program User Guide or Help feature for instructions
on configuring the serial port communications and for creating a nd saving text
capture files.
You are now ready to begin pre-reboot collection of diagnostic information from the CDM-625 Field Unit.
