I-CHIP PORT
4.2.6 I-CHIP Programming Port
(Fig. 17)
The I-CHIP programming port, located on the decoder module (refer to Fig. 17 above) inside the
receiver, is designed for the purpose of transferring a system serial number/ID code from the I-
CHIP to the receiver or vice versa. If you wish to transfer system information from the receiver to
the I-CHIP, just insert the I-CHIP onto the programming port (JP6 jumper not inserted), wait until
the Status LED on the decoder module turned displays a constant green light (within 2 seconds),
and then take the I-CHIP out of the programming port (programming completed). At this time the
I-CHIP should also possess the same serial number/ID code as the receiver.
If the Status LED on the decoder module displays a constant red light after inserting the I-CHIP
(programming failed), then you must reinsert the I-CHIP one more time. On the other hand, if you
wish to transfer system information from I-CHIP to receiver, then you must first insert JP6 jumper
prior to inserting the I-CHIP, then wait for the green light to appear on the Status LED. At this time
the receiver should also possess the same system information as the I-CHIP. Please note that the
receiver unit must be powered in order to proceed with the programming.
