3 Testing
The following information is for technical service personnel; Unitec does not recommend end
users repair their own equipment. However the following information may be useful in helping
the end user to get his or her system up and running without requiring a service call from the
local equipment distributor.
3.1 Console Testing
During the installation and normal operations of the POS4000, there may be times when the
system doesn't operate as expected. For example, power to the system interface card may be
off. In order to expedite the checkout of the system, several service routines are provided. To
access a service routine, press the [CMD] key followed by the [SERVICE] key. The console will
request password level 4. Password 4 is always 62747. It cannot be changed and is intended for
service personnel to use for installation and testing purposes. This is the only command that
password 4 provides access to. For a specific discussion of this command, see Section 4.6.
3.2 Interface Board Testing
The POS4000 interface board has a test mode of operation. To activate this test mode you must
change the dip switches on the interface board as follows:
Table 7. Interface Board DIP Switch Setting for Test Mode
DIP Switch Setting
4 OFF
5 ON
Make sure you return the DIP switches to normal operation mode when testing is complete. For
the normal operations, set the switches as follows:
Table 8. Interface Board DIP Switch Setting for Normal Operations
DIP Switch Setting
4 OFF
5 OFF
While the interface board is in the test mode, the customer buzzer will beep approximately every
5 seconds. Once in the test mode, you select the specific test desired by typing the following
codes at the customer keypad:
