1 Mini4 Data Mux Board P/N – 201780-xxx

The Mini4 Data Mux boards are typically used as a set. This board set provides for 4 channels of RS232 data and 4 channels of RS422/RS485 data. In addition, the Mini4 Data Mux boards provide for the use of one or more daughterboards for additional data channels.

NOTE: For details on a specific daughterboard, refer to the daughterboard manual. For a current list of available daughterboards, please contact the factory sales personnel.

2 Mini4 Revision History

The Mini4 Data Mux board (201780-xxx) has gone through the following printed circuit board (PCB) revisions:

PCB Revision A Original design, not currently in production. PCB Revision 01 Respin to correct routing.

3 Mini4 Data Mux Board Dash (-) Number Definitions

The Mini4 Data Mux boards have a Dash Number appended to the part number. This Dash Number identifies the specific board configurations:

-01 Subsea Bottle custom version.

-02 Surface custom version.

-001 Standard version.

4 Mini4 Data Mux Board Operation

The Mini4 Data Mux boards include the fiber optic link interface, 4 channels of RS-232 data and 4 channels of RS-485 or RS-422 data. The boards interface to all of the on-board peripheral devices (such as the fiber optic link chips (SERDES) and the data interface chips) through a programmable logic device. The boards also provide the interface for a daughterboard connection. A block diagram of the basic Mini4 Data Mux Board I/O is shown on the following page and explained in the subsequent paragraphs.

The transmit portion (uplink from vehicle to surface) of the Mini4 Data Mux board takes in the 8 onboard serial data signals and the daughterboard data and clock signals and converts them to a single serial optical signal. The signal is transmitted to the Mini4 Data Mux board at the other end of the fiber optic link in the control/viewing area. The receive portion of the Mini4 Data Mux board accepts the optical signal, recovers the 8 serial data signals and routes them to the appropriate RS-232/RS-485/RS-422 driver chips, and recovers the daughterboard clock and data signals and routes them to the daughterboard connection. The downlink from the surface to the vehicle is identical to the uplink portion.

LED

Indication

D1 (Green)

Located at the top left of the board serves as an indicator that either +5V or 3.3V dc is available to the board connector, J2. Supply voltage (5V or 3.3V) to the daughterboard is selected via the placement of fuse F6 (3.3V) or F5 (5V)

D3 (Green)

Located on the top middle of the board, labeled „FIBR‟, provides an indication that the transceiver module has detected the presence of an input signal on the fiber link.

When „ON‟ indicates that this board has a good level of received optical power from

the remote unit.

D6 (Green)

Labeled „2.5V‟, located on the mid-right of the board. When „ON‟ indicates the onboard 2.5V converter is operational

D7 (Green)

Not labeled, located on the bottom center of the board. When „ON‟ indicates that 5V is available to the display LED ribbon header.

D8 (Green)

Labeled „5V‟, located on the lower right of the board. When „ON‟ indicates +5V dc

is available to the board.

D9 (Green)

Labeled „3.3V‟, located at bottom center of the board. When „ON‟ indicates 3.3V is

available on the board.

LED

Indication

D10 (Green)

Located on the upper right corner of the board, labeled “REM”. „ON‟ when the link is established with the remote Mini4 Data Mux board and the data stream is synchronized at the remote board‟s end.

D12 (Green)

Located on the upper left corner of the board, not labeled. When the RS-485

diagnostics processor has been accessed, this LED will toggle from “ON” to “OFF”

with each successive access.

(201780-xxx)

The Mini4 Data Mux boards require a +5VDC power source provided through the 2-pin Phoenix connector at J5. The boards have on-board 5V to 3.3V and 2.5V converters to provide power for the components that use these supply voltages.

4.1 Mini4 Data Mux Board Indicator and Controls

LEDS: There are 19 surface mount (SMD) LED indicators on the Mini4 Data Mux board to indicate different statuses that are covered by function below.

D13 (Green)

Located on the upper right corner of the board, labeled “LOC”. „ON‟ when the link

is established with the remote Mini4 Data Mux board and the data stream is synchronized at this board‟s end.

D18 (Green)

Located on the upper left of the board, labeled “TD”. „ON‟ when serial data is being transmitted out of the board by the RS-485 diagnostics processor.

D22 (Green)

Located on the upper left of the board. „ON‟ when serial data is being received by the RS-485 diagnostics processor.

D24 (Red/Green)
