Chapter 2 Installing the Option Module
Setting the IP Address
Selection Jumper
The IP Address Selection Jumper ( Figure 1 ) determines the source of the
network address for the option module.
Figure 1 - Setting the IP Address Selection Jumper
Using Default Network Address
When the jumper is on Pins 2 and 3 and
Device Parameter 16 - [DHCP] is set to
‘0’ (Disabled), the following default network address is used:
• IP Address 192.168.0.1
• Subnet Mask 255.255.255.0
• Gateway 192.168.0.1
Using DHCP Server
When the jumper is on Pins 1 and 2 and
Device Parameter 16 - [DHCP] is set to
‘1’ (Enabled), the network address is configured from a DHCP server. To set an
IP address using a DHCP server, do the following.
1. Set
Device Parameter 16 - [DHCP] to ‘1’ (Enabled) to select the DHCP
server as the source for the IP address.
2. Reset the option module; see Resetting the Option Module on page 33 , so
it can get the new IP address from the DHCP server.
Using Option Module Parameters
When the jumper is on Pins 1 and 2—or there is no jumper—and
Device
Parameter 16 - [DHCP] is set to ‘0’ (Disabled), the network address is
configured with option module parameters.
