For each deployment, a 'Mooring
Roadmap' is created and issued by the mooring support group, indicating the
instrument list and its mapping into OASIS I/O ports. This indicates how the
can is physically wired and contains some of the information necessary to configure
the OASIS software.
A sample Mooring Roadmap follows:

| Power bit | Bit Vector Position of Power Enable Bit The OASIS software represents the power state of instruments using a single bit in a power word. Logical 1 represents a Power On. The power word is also used at the physical power interface to switch the instruments on and off. Example: An instrument with power bit=9 may enabled by ORing the power word with 0x0200 |
||||||||||||||||||
| Serial Port |
Serial Port The 8 UARTs (see below) in the OASIS3 controller are multiplexed as follows, yielding a total of 32 serial ports
|
||||||||||||||||||
| UART | UART There are eight UARTs in the OASIS3 controller. The first UART, designated 0, is the SCI console port from the CF2 and must be assigned to the User I/F. UARTs 1-7 are built from the TPU ports. UARTs 0-3 exist on the OASIS3 CPU board, and are not multiplexed. UARTs 4-7 are on the OASIS3 I/O boards, one per I/O board, and are multiplexed 7:1. |

| Connector Section | Physical Connector ID Each instrument plugs into a 6-section pie connector on the top of the OASIS can numbered 0-2. The sections are further identified by a letter , A-F (section A is usually also painted white), stamped into the connector and proceeding sequentially clockwise from A. |
