LEDs
NOTE
DS1 and DS2 should be on solid. If they are blinking, it indicates that something
(e.g., Reader, I/8, R/8, etc.) is configured in the software but is not seen by the
hardware. This may or not be a hardware failure, depending on the intent of the
technician. (i.e., It is possible to configure hardware before actually installing it.)
If DS1 and DS2 are blinking, it causes some overhead to the iSTAR.

RS485 Ports
(STAR1-STAR8)
These switches default to ON and
generally should not be changed. Setting
the switch to OFF places the STARn port
in the middle of the RS485 chain, which
allows the technician to connect two
sections of a reader bus to this point. In
this case, termination must be provided
at the end of each of those connections,
but not at the STARn connector.
See Figure 8 on page 17.
