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. The following
diagram shows the standard connection, where the units are daisy chained together and one unit is
directly connected to the laptop/PC, all with Ethernet cable. For other connection options, please refer
to Sections 2.1 and 4.
To connect non-Ethernet units in an Ethernet-to-serial system
The non-Ethernet units are daisy-chained using serial RS-485 cabling. The first 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 using Ethernet cable; see Section 4.
To set up the Lantronix UDS1100 converter, please refer to the "HELIX Remote Control Software: Brief
Guide to Setting Up an Ethernet System" User Guide.
In this system the speed of operation is limited by the serial connection.
