Display/Switch Setting (continued )
*1 : Remote control (SW1 all dip-switches off)
SMC's EX500 GW Unit will respond to the following Rockwell Automation
BOOTP/DHCP Server commands.
Enable DHCP
Selecting this function will enable the EX500 GW Unit to retrieve its boot information
from the BOOTP/DHCP Server. If DHCP is enabled the EX500 GW Unit will retrieve its
boot information during the next power up.
Disable BOOTP/DHCP
Selecting this function will disable the EX500 to retrieve its boot information from the
BOOTP/DHCP Server, and causes the EX500 to retain its current configuration during
the next power up.
*2 : DHCP Mode (SW1 all dip-switches on)
The IP address is acquired via DHCP Server. The IP address is not saved and lost if the
power to the EX500 unit is cycled.
*3 : Hardware Addressing
The IP address range is 192.168.0.1-192.168.0.254.
Default settings
At the time of factory shipment, the product is in "Remote Control Mode" and set to
"Enable DHCP".
NOTE
If the stored IP address of an EX500 is not known, please go to the "DHCP Mode" section.
