LED Connections
LED Control
LED control on the iSTAR eX GCM is for read heads connected to iSTAR eX
GCM Wiegand ports.
LEDs on read heads connected to the iSTAR eX PMB RM ports are controlled
by the RM-4 or RM-4E.
Jumper 2 (JP2) and Jumper 3 (JP3) on iSTAR eX GCM provide the same LED
control that is available on the RM-4 and RM-4E except that the External Bi-
color 1 wire (yellow) mode is not supported.
Table 4.2 shows the possible jumper settings and functions of JP2 and JP3 on
iSTAR eX GCM.
