Upon boot, Rhino™ locks up while
executing a program or a driver.
Reset Rhino™ and press the “F8” key during the
memory check. This implies a “Step-by-step” boot
activation.
Press the “y” key to confirm (execute) each
program/driver until the one that locks Rhino™. Once
found the locking program/driver, repeat the procedure
from the beginning and skip the execution of the
incorrect program/driver by pressing the “n” key.
If problem persists, format the disk C: and load a fresh
configuration.
If problem still persists, contact the nearest Datalogic
distributor for technical assistance.
The barcode reader (either Laser
or CCD) emits no light source.
Check whether one of the following conditions has
occurred:
- Ensure the right cable is being used, then check
the correctness of cable clamping;
- If connected to COM2/Scanner port, check whether
the right cable is being used. That implies that
power supplied through the serial connector is
compatible with Rhino™ COM port.
- Since COM1 does not allow the powering from
external devices, check the right cable is being
used and that the reader receives external power
(check also power source correctness: refer to
reader user's manual).
The barcode reader does not read
some code symbologies.
The type of barcode readers that can be used with
Rhino™ are "Decoded" readers: therefore, they require
a dedicated configuration. Refer to reader user's
manual for configuration.
The barcode reader emits a laser
beam and a good read beep but
the read barcode is not displayed
by the application running on
Rhino™.
Check whether one of the following conditions has
occurred:
- the RS232 parameter settings of the barcode
reader do not correspond to the Rhino™ settings;
- the “redir.sys” driver has not been loaded (check
the “newcfg.sys” configuration file in Disk C:) or has
not been configured correctly;
- the barcode reader is connected to a serial port
(COM) different from the one used by the
“redir.sys” driver;
- the Datalogic Transfer Protocol Server (DTPS)
program (ds.exe) has been used through the COM
port already used by the “redir.sys” driver. In this
case, it is necessary to reset Rhino™;
The barcode reader emits a laser
beam but it hardly reads the
barcode.
Ensure that the reading window of the barcode reader
is clean. If not, clean it with a slightly dampened cloth.
Do not use alcohol, corrosive products or solvent, and
avoid any abrasive substances.
