Troubleshooting and Maintenance
9-5
2 The baud rate is selected
correctly but nothing
happens.
The Encompass 4 Reader is not communicating with your PC.
Check the power supply to your PC, and check the
connections between the PC and the Encompass 4 Reader.
Try reversing the receive and transmit connections.
3 When testing the
Encompass 4 Reader, all the
wires are connected
correctly but the unit does
not respond.
The Encompass 4 Reader may not have the software loaded
inside the unit. Contact Technical Support as described on
page 9-
7.
If you are using a terminal emulation program, check that the
terminal emulation setting on the Encompass 4 Reader is
VT100.
Check that the Encompass 4 communication cable is
connected to the correct COM port.
Verify that the external antenna is connected correctly.
4 Strange signal responses
come from the Encompass 4
Reader when tested with the
PC.
Ensure that the reader is in the correct interface mode for the
test tag, i.e., Wiegand mode for a Wiegand tag. If using
hyperterminal, Wiegand tag data may display as unintelligible
characters.
Check the system defaults using a terminal emulation
program. Both PC and reader should be set to 9600 baud, 8
bits, 1 stop bit, and no parity.
5 When a tag is moved in front
of the reader or external
antenna, a clicking sound
comes from the Encompass
4 Reader.
The Encompass 4 Reader works. The sound is the relay
inside the Encompass 4 Reader that is controlled by a lock
signal. The relay is actuated when a tag is in the read zone.
6 Nothing happens when the
test tag is passed in front of
the Encompass 4 Reader or
external antenna.
Ensure that the Encompass 4 Reader is powered on and is in
predefined output mode. (#621)
Verify that the reader is set to RF ON (#6401).
Verify that the external antenna is connected correctly.
Verify that the reader mode matches the test tag.
7 The Encompass 4 Reader
came from another site and
does not work the way the
factory defaults indicate that
it should.
Different commands were probably used to support the other
site’s specific configuration. You can restore the factory
defaults by using a terminal emulation program to switch to
command mode and issuing command #66F Load Default
Operating Parameters. All factory defaults except RF
frequency will be restored.
