Overview and Introduction
5
4 reader model, 8- I8 and 8- R8 allowed to be configured on any of the three RS-485 ports or
the optional 2 RM-4s.
Special purpose inputs:
Tamper (from enclosure door)
Main AC fail (from apS)
Low external battery (from apS)
FAI Supervision State (J40 F input)
FAI Relay Control
FAI Key Supervision State (J40 K input)
Onboard battery low
3 RS 485 serial ports.
USB Ports
2 USB host ports. (These are the
wide and flat
USB connectors used by memory sticks,
used when the iSTAR Edge is the
host
of the attached devices.)
1 USB device port. (This is the
square
connector used when the iSTAR Edge itself is the
client
device.) (not currently used)
The only use of USB in the first version is to import encryption keys, in the same way as
iSTAR eX.
Communications
One 10/100 Ethernet port.
No secondary communication path.
Full 256 bit AES encryption, as with iSTAR eX
Can cluster with other iSTAR Edges
Can cluster with iSTAR eXs
FAI
Fire Alarm Interlock - When the F input is true, FAI activates relays that are enabled for
FAI by individual enable switches.
Latch option is available by switch control. If the selected relays are latched, they will be
cleared to normal by the key (K) input.
Onboard controls
LCD with backlight for diagnostics.
Rotary switch for diagnostics, as with iSTAR eX.
LEDs for serial, Ethernet, power and relay state.
Two power LEDs: one
super bright
LED that is on when the enclosure door is closed,
and one green LED that is always on when main power is present.
Relay activation LEDs are not affected by enclosure door.
NOTE
The following 4 inputs to the host are determined by the firmware. There is no actual
wiring to the iSTAR Edge board.
