RM Port Termination
Switches
Each of the RM ports have a switch that controls whether there are two 110 ohm
RS-485 termination resistors on the iSTAR Edge end of the RM Bus. In most
cases, leave this switch in its default (ON) position. When retrofitting an iSTAR
Edge to reuse readers that were previously on an iSTAR Classic it may be
desirable to turn off the termination. Another possibility would be the need for
a four way STAR arrangement of RM busses.
Output Relay Wet or
Dry Jumpers
The four output relays can be either Dry or Wet based on the position of these
jumpers.
When Dry the integrator must supply the external power that the relay
switches. When set to Dry, use the C, NO, and NC connections.
When Wet the iSTAR Edge sources the power. When set to Wet, use the
GND, NO, and NC connections. Be sure to stay within the power budget
when using the Wet setting and powering by PoE.
PoE or PoE Plus
Jumper
The PoE board has a set of 8 jumper locations. The right most jumper location
indicates PoE+ and the one left of it indicates PoE. Put the one jumper on the
appropriate location.
