IT-2060IOE Optional Optical Communication Unit
Daisy Chaining Optical Communication Units
An optional DT-888RSC 6-6 Pin Modular Cable can be used to daisy chain up to seven
Optical Communication Units. In this configuration, a personal computer can exchange data
with multiple Data Collectors simultaneously.
Daisy Chain Configuration
Connect the C-OUT terminal of the Optical Communication Unit that is closer to the host
computer to the C-IN terminal of the next Optical Communication Unit.
The following are the required DIP switch settings for Optical Communication Units in a
daisy chain configuration. See page E-43 for details on actually making DIP switch settings.
• The Optical Communication Unit furthest from the computer must be defined as the
“Terminator Unit in Linked Chain.”
• The Optical Communication Unit connected to the computer must be defined as the “Host
Computer Connection.”
• All other Optical Communication Units must be defined as “Intermediate Unite in Linked
Chain.”
