4.4.2 F100 DHCP – DHCP Control

Use F100 DHCP to enable or disable Dynamic Host Configuration Protocol. DHCP

allows the unit to auto-configure its network address, provided that you have enabled

DHCP, and that the unit is installed on, and connected to at power-up, an Ethernet LAN

with a DHCP server. If these conditions are not met, the unit reverts to those network

parameters in use at the last power-down. By default, DHCP is off at initial installation.

To enable DHCP, send the following command:

F100<SP>DHCP<SP>ENABLE<Enter>

where:

F = ASCII character F

100 = unit function number

<SP> = space

DHCP = specify DHCP command

ENABLE = command DHCP to be enabled

<Enter> = input line terminator

To disable DHCP, send the following command:

F100<SP>DHCP<SP>DISABLE<Enter>

where:

DISABLE = command DHCP to be disabled

The unit responds:

Are you sure? (y/N)

As a safety feature, after sending this command you have 10 seconds to respond

affirmatively (enter the letter “y”) to the confirmation prompt, after which the unit

executes the command and resets. Within that 10 second time period, any other response,

including no response, results in the unit canceling the command.

To query the status of DHCP send:

F100<SP>DHCP<Enter>

An example of the response is:

F100 DHCP OFF

Disable DHCP before changing any Network parameter. Changing DHCP status causes a

software reset of the unit. DHCP status can be queried without rebooting the unit.
