TROUBLESHOOTING
If the following instructions fail to solve your problem, contact Pelco Technical Support at 1-800-289-9100 for help. You should have the
serial number from the bottom of the unit and the firmware version ready in case they are needed.
Do not try to repair a unit yourself. Opening it immediately voids any warranty. Leave maintenance and repairs to qualified technical
personnel. Swap a defective unit with a replacement unit and return the defective one for repair.

TERMINAL PROGRAM
• Is the right COM port interface on the PC selected for the terminal program, and are the settings correct? Is the cable connected to
COM 1 and not COM 2 on the PelcoNet unit? Program default settings are 19200 kb/s, 8 data bits, no parity, 1 stop bit (8N1) for the
terminal program.
• If the data exchange between the terminal program and the system still does not work, check the serial cable. Does the system
answer when you press the Enter key?
• Disable the local echo if you see duplicate characters on your screen.
TROUBLESHOOTING A TCP/IP NETWORK USING A PING UTILITY
(Enter the appropriate information where indicated by the quotation marks below. Do not enter the quotation marks.)
To see if a unit in your network can be reached, try to ping your unit by typing the following command in a DOS window:
c:\ping ‘unit IP address’
If it is reached, there will be a response like the following:
Reply from <IP address>: bytes=32 time=NN ms TTL=xxx
If the LAN path is malfunctioning, the ping command will time out. If so, you could have one of the following problems:
• Wrong physical connections. Make sure the green Ethernet LED is on.
•Wrong network connection. Verify the IP address is entered correctly and that subnet mask and gateway address are set properly.
Otherwise, ask your network administrator.
