The point identification PI in M5 Format
The PI is comprised of 27 characters. It starts in column 22 and terminates in column
48 in the M5 data line. The data structure within the PI is defined by markings. A
maximum of 10 markings, marked in the preceding type identifier with PI1 to PI0
(columns 18, 19, 20), can be designated to the PI (depending on the instrument).
The type identifier in the M5 Format
Data format requirements have changed and increased over the years. For backwards
compatibility, the M5 Format carries most of the type identifiers of all available
formats, always based on the preceding format (Rec500).
Type identifiers are defined by two characters (except for Adr). If only one character is
necessary, the second character is a blank.
In the M5 Format there are five type identifiers (TK) defined:
• TK1: Adr Identifier address (Value1)
• TK2: T2 Identifier information (Value2)
• TK3: T3 Identifier 3. Value field (Value3)
• TK4: T4 Identifier 4. Value field (Value4)
• TK5: T5 Identifier 5. Value field (Value5)
Example: PI for point identification or TI for text information can be used for T2. For
T3, T4, T5, D, Hz, V or Y, X, Z can be used.
The Special characters, page 130 are analogous to the M5 format.
B8.3 Marking in the M5 format
The Trimble M3 total station uses a mark which is saved internally in the instrument.
This mark consists of three blocks with clearly defined block lengths. The user can
change the order of the point number and point code blocks as well as the position of
the information block.
