Rice Lake Digital/Diagnostic - iQube - Manual (Page 9)

6 iQUBE Installation Manual
DIP switches on the core module of each iQUBE must
be set to indicate whether the unit is a primary or
secondary, the communication protocol and port used,
and the secondary address.
• For the primary unit, DIP switches 1–3 must
all be set OFF. Set switches 5 and 6 based on
the protocol (RS-232 or RS-485) and port (J7
or J6) used to communicate with the host
device.
• For secondary units, DIP switch 5 must be set
ON; use switches 1–3 to set the secondary
address as shown in Table 2-5.
See Section 2.9 on page 10 for more information
about the core module DIP switches.
