12.9 Serial Port Test
At the Self Test Menu
screen, press the 8 key for Serial
Port Test. The scale will then
display the Serial Port Test screen.
Before you continue from
this screen, you need to place a
loop-back plug on the 9-pin serial
port on the side of the scale. The loop-back plug needs to be a 9-pin male connector with pins 2 & 3
shorted. Once you have done this, press any key. If the serial port is working, you will see the message
“RS-232 Test Passed” on the screen. After a few seconds, it will return to the Self Test Menu. If it fails, you
will see the “RS-232 Test Failed” on the screen. You may press ESC to exit or any key to try again.
If you are having problems with this test, please make sure that the loop-back plug is connected
properly and that it has pins 2 & 3 shorted. If the problem persists, you may have a damaged
connector or serial port driver.
12.10 Firmware Versions Test
At the Self Test Menu
screen, press the 9 key for
Firmware Versions Test. The scale
will then display the Firmware
Versions Test screen.
This test can help you
determine the versions of all of
the scale’s ROMs without having to take the scale apart. This feature can also be accessed from scale
mode by pressing ESC and then HELP. This can also help with customer support over the phone, as it is
not necessary to enter CAL mode to get this information. ROM #5 may not appear on all versions of LP-
2.
A list of ROM versions, checksums, brief descriptions, and BIN files will be available on our website.
The availability is TBA. As of October 1999, all ROM versions are 1.00.
