Reader Problems
Multiple reader technologies on the same Controller.
On first power up with a reader connected or after a ACU reset, the LED reader will flash
quickly (twice a second), presenting a correct technology card to the reader will make
the reader flash to the normal mode of 1 flash every 2 seconds- this has detected the
reader type and enabled it into the controller memory. If you have a different reader
technology being used on the other reader channel then this will need programming
independently to get functionality.
Reader LED goes out when a card is presented.
The system default for a reader LED is Bi-Coloured so you may find that the LED goes out
when you present a card. If this occurs change the LED type to Red Only.
Reader LED's are not flashing rapidly.
On initial power up, if the readers are not flashing rapidly (about twice every second)
then do a system reset. This is done WITH THE POWER ON by placing the reset jumper J1
across the pins for about a second or so and then removing it. The reader LEDs will then
start to flash rapidly ready for card presentation to the reader.
Readers with Separate Power Supplies
With Any readers that uses a separate power supply then ensure the Readers Ground 0V is
connected to the ACU Ground 0V thus they are at the same Ground.

Reader not working
Present a card to the reader, does the reader respond or bleep?
1.
a. If not then the Card is not the same technology as the reader type OR the card is
faulty.
b. If yes, then the card is being recognised by the reader.
2.
Has the reader been wired according to the instructions supplied with the reader?
This is important because colour codes may change from time to time and also
reader outputs can be switched by connecting in different ways (i.e. Wiegand,
Magnetic, RS232 etc.).The EX-Series will detect many types of reader but if a 3rd
party reader is being used you may need pull up resistors (normally 1kΩ to the 5V
output). If the reader has a Wiegand output then the reader type may need to be
set manually either via XKDX (in EXgarde toolkit) or in the software.
Present a card to the reader, are you getting any event at all in the EXgarde software
3.
event trail, or on XKDX software screen?
a. If not then check wiring for clock and data or W0 and W1. No signal is getting to
the ACU.
b. If yes then what is the message? If using the XKDX (software) screen Refer to the
list below. If you are using the EXgarde software then this should tell a message
helping you identify why it is not working.
Reader Error: Other messages to look for are "Reader error" this refers to the wrong reader
type has been set for the reader OR the signal from the reader is getting "interfered with"
along the cable and the ACU sees it as a garbled message. Check the cable, screening
of the cable, is the reader on metal or poor cable quality, kinks, breaks, bare wires,
external cables/peripherals inducing noise.
Reader Gone, or Reader Back: This implies the reader was disconnected, or reconnected,
either on the power supply lines, or on the data signal lines. Check the wiring, reader
