Addendum B — Phase 1.5/1.5.3 and New Main PCB
B–9 Addendum B
B.2.2 Printer attached options added
See Table B.1: Machine Configuration, Digit 12 – Printer Attached.
Options 3, 4, 5 and 6 have been added to cater for the improved ‘polling‘ of the
connected printers. This ‘polling’ informs the scale of the type of printers
attached so that it can use the correct scale/printer communications protocol.
From Phase 1.3 onwards, CX/Advantage scales have been able to
communicate with up to three printers, one internal and two external. During
this time printer types have changed and, therefore, so has their scale/printer
communications protocol. To ensure scale/printer type compatibility scales have
to know the type of each printer attached.
Previously the scale has found out the printer type by interrogating them only
when the power was switched on – if a printer had not been switched on the
scale would display an appropriate error message and would stop functioning.
Now, if a printer has not responded when the scale is switched on, the scale
carries on working and this printer is ‘polled’ until it switched on. A message is
displayed if the operator attempts to use an off–line printer.
The ’polling’, which is approximately once every second, has no apparent
detrimental affect on the functioning of the scale and ceases when all the
printers are on–line.
B.2.3 Multimedia interface
See Table B.1: Machine Configuration, Digit 13 – Multimedia Interface.
This option (UK only) is for a multimedia PC.
B.2.4 ADF wrapper
See Table B.1: Machine Configuration, Digit 17 – Wrapper.
An applied direct to film (ADF) wrapper can be connected to the scale.
Note the differences in digits 17 and 18 in Phase 1.5 and 1.5.3.
