Using A Four-Slot Ethernet Cradle; Dhcp Mode - Symbol PPT 8800 Series Product Reference Manual

Using a Four-Slot Ethernet Cradle

The CRD8800-4000E Four-Slot Ethernet Cradle allows communication between terminals
and their associated host computers connected to an Ethernet network using ActiveSync
and eConnect. The CRD8800-4000E must be connected to an Ethernet network which is
connected to the same network as the host computers, or an Ethernet network connected
to the larger Internet via an Internet gateway. The cradle uses one of two configurations to
accomplish this: DHCP mode or Static mode.
ActiveSync only allows one terminal to connect to a host at a time. eConnect is a required
control panel applet that is installed on the terminal and allows ActiveSync, or any custom
synchronization application, to be launched when the terminal is inserted into the cradle.
eConnect can also be set up to start a TCP/IP connection with the cradle, allowing any IP-
based application to communicate through the cradle. When the terminals are inserted in
the cradle, the cradle appears to be a direct-connect PPP service.
The cradle must be properly configured for use with the terminal. The configuration steps
include:
• Connecting the cradle to a network
• Configuring the cradle
• Configuring the host computer
• Configuring the terminal.

DHCP Mode

1 DHCP Address Mode
When using DHCP mode, the cradle acquires its IP address dynamically from the DHCP
server. There must be a DHCP server or a DHCP relay agent on the same subnet as the
CRD8800-4000E with IP addresses, a gateway IP address, at least one DNS address, at
least one WINS server address, and a subnet mask for the unit to be automatically
configured. The cradle acquires one DHCP address from the DHCP server.
6 DHCP Address Mode
The 6 DHCP address mode is the cradle's default mode. When using this mode, the cradle
acquires 6 IP addresses dynamically from the DHCP server: one for the cradle, one for
each of the 4 slots, and one for the expansion slot.
In this mode, each slot has its own IP address and may be directly accessed by the
network. On power-up, the 6 IP addresses are acquired. Periodically, the lease times are
checked and renewed as required. If the renewal request is NAKed by the server, the cradle
