All PCBs are identified by a unique 10 digit ‘internal part number’ (IPN), e.g.
220-01330-02, which is screen printed onto the PCB (usually the top side).
The last 2 digits of this number define the issue status, which starts at 00 and increments
through 01, 02, 03, etc. as the PCB is updated. Some issue PCBs never reach full produc-
tion status, and are therefore not included in this manual. A letter following the 10 digit
IPN has no relevance in identifying the PCB for service purposes.
In the following diagram of the T2000-66 UART PCB, the IPN is 220-01348-03, (i.e. issue
03 of the PCB).
It is important that you identify which issue PCB you are working on so that you can
refer to the appropriate PCB information.
The 10 digit numbers (000-00000-00) in the parts lists are ‘internal part numbers’ (IPNs).
Your spare parts orders can be handled more efficiently if you quote the IPN and pro-
vide a brief description of the part.
The components listed in the parts lists are divided into two main types: those with a
circuit reference (e.g. C201, D106, R121, etc.) and those without (mechanical and miscel-
laneous).
Those with a circuit reference are grouped in alphabetical order and then in numerical
order within each group. Each component entry comprises three or four columns, as
shown below.
The mechanical and miscellaneous section lists the variant and common parts in IPN
order.
A variant component is one that has the same circuit reference but different value or
specification in different product types, models or options. Variant components are indi-
cated by a character prefix, such as ‘&’, ‘#’ or ‘=’.

To assist in locating components and labelled pads on the PCB layouts and circuit dia-
grams, a component grid reference index has been provided. This index lists the compo-
nents and pads in alphabetical order, along with the appropriate alphanumeric grid
references, as shown below.
!
Reading a circuit diagram is similar to reading a road map, in that both have an alpha-
numeric border. The circuit diagrams in this manual use letters to represent the horizon-
tal axis, and numbers for the vertical axis. These circuit diagram ‘grid references’ are
useful in following a circuit that is spread over two or more sheets.
When a line representing part of the circuitry is discontinued, a reference will be given
at the end of the line to indicate where the rest of the circuitry is located. The first digit
refers to the sheet number (printed on the bottom right hand corner of the circuit dia-
gram) and the last two characters refer to the location on that sheet of the continuation
of the circuit (e.g. 1-D4).
If more than one line is represented (indicated by a double thickness line), a dot with a
reference label will follow the route each individual line represents.
