2. Confirm the beeper is audible when a good tag is presented with a steady BEEP.
3. Check that the RED and BLACK wires are installed correctly to our supplied power
supply, the warranty is based on its use.
4. Check the voltage at the Reader pigtail cable, if you under cabled the voltage drop would
be too much to power up the Reader.
Q: Reader just beeps and keeps beeping, about 3 x per second
1. If a week constant audible BEEP when power is applied and no tag presented, means
reader is either damaged or not enough current is being supplied.

4. Check the voltage at the Reader pigtail cable, if you under cabled the voltage drop would
be too much to power up the Reader. Verify the voltage supplied to the Reader is
between 8 and 16 VDC
Q: Reader does not recognize a tag (no beep, no outputted tag data)
1. If no beep, check to see if another tag works, maybe the tag is damaged.
2. Verify Reader operations by connecting to a computer through the RS232 port and
running a Terminal program. Install guide will help you with connectivity.
Q: Tag data to panel is scrambled or Reader beeping and host not responding
1. One or more of the Reader’s wiring connections are incorrect. Power down the reader
and panel and verify the wiring connections are correct. Check that Data 0 (GREEN
wire), Data 1 (YELLOW wire) and ground (GRAY wire) are properly attached.
Caution: some panels use the Wiegand Ground (GRAY wire) to be connected to
either the panel ground or to the power supply ground.
2. Earth Ground should terminate at the back of the Reader through the mounting brackets.
3. Do not wire another manufacturer Wiegand output to same terminal as tres900
4. Cable between Reader and panel is too long, check Wiegand specifications
5. Check to insure the tres900 tag number / site code are properly programmed in the host
panel.
6. Check the Wiegand timing that your host is looking for and insure their timing scheme is
within the SIA standard parameters.
7. Check to insure the tres900 tag number / site code are properly programmed in the tag,
connect via serial port and read tag.
Q: Read Range too short
1. Ground loop could be an issue here, see if earth ground terminates at the reader. Check
by powering reader without reader ground wire connected. Earth ground should terminate
at the Reader, check your panel or power supply.
2. Reader orientation, is it pointing down too much, when center pointed to earth read range
ends at that point
3. Tag orientation should be in a vertical position for the Readers Antenna maximum
performance and distance.
4. Verify thru the Setup program that the power level is set to 30 dBM
Q: Reader reading cars in another lane
1. Reader orientation is it pointing too much toward the other lane. Remember that from
center of reader you have 4' pattern on all side, an 8' read zone. Point away from other
lane.
