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.

S2
Enable Wiegand
Ports
You can have any combination of Wiegand
and RM readers on one ACM, but they cannot
share the same reader number. If readers 1, 2,
3, and 4 are RM readers, then the Wiegand
readers would have to be 5, 6, 7, and 8. In this
case,
S2-1
through
S2-4
must be
ON
, and
S2-
5
through
S2-8
must be
OFF
.
S4
Terminate
the
RM
RS485 Ports
(STAR1-STAR8)
These switches default to
ON
and 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.
This function is provided for compatibility
with older iSTARs. If an iSTAR Classic is
being ported to the iSTAR Pro, there are now
eight RM ports per ACM instead of four.
