12.2.2 Multiple-unit Ethernet connections
To connect any Ethernet units in an Ethernet system
This fast Ethernet-only system can incorporate the Ethernet units in any combination. Connect the units
using Ethernet cable, using one of the options in Section 11.2. The first unit is connected to the
laptop/PC via an Ethernet cable. The Ethernet cable can be connected direct to the laptop/PC or to a
wireless access point for wireless operation.
To connect non-Ethernet units in an Ethernet-to-serial system
The HELIX DN9848 units are daisy-chained using serial RS-485 cabling. The first HELIX DN9848 unit is
connected to a Lantronix UDS1100 Ethernet-to-serial converter via either a serial RS-232 or RS-485
cable. Connection to the laptop/PC can be either direct from the Lantronix unit or via a wireless access
point for wireless operation; both these options require Ethernet cable.
To set up the Lantronix UDS1100 converter, see Section 12.3.
In this system the speed of operation is limited by the serial connection.
