Trimble Standard Interface Protocol A

A.2.1 Nomenclature

Historically, the ports of the Smart Antenna product lines which include Acutis, Acutime and Palisade products, have been described using letters "A" and "B". The board-level products, such as Lassen, Ace and Core Module 3, have historically used port numbers "1" and "2" to label the ports on the starter kit.

The Acutime 2000 ports are referenced by letters "A" and "B", conformant to standards established by the Palisade product line.

The Ace UTC ports are referenced by numbers, conformant with the conventions of previous board-level products.

This manual reconciles the naming schemes of both receiver lines, and generally refers to the ports using the Ace UTC convention of using "1" and "2". Exclusively, where designations apply only to Acutime 2000, the ports will be referenced as letters "A" or "B".

The following tables can be used to cross reference the port identifiers:

Table A-1 Ace UTC Port Translation Table

Function	Label	Internal
Primary	Port 1	Port 0
Secondary	Port 2	Port 1

Table A-2	Acutime 2000 Port Translation Table
Function	Label	Internal
TSIP	Port B	Port 0
Timing	Port A	Port 1

A.2.2 Protocol Capabilities

The I/O ports of Ace UTC and Acutime 2000 are highly configurable. Port settings are stored in non-volatile memory, and are retained across power outages.
