5.6.6 MS-900 Analog Sonar Plug-In (AIB-MS900)
Card P/N 903-0250-00
The MS900 Analog Sonar Interface AIB plug-in (AIB-MS900) uses only one configuration jumper, J11,
shown below in Figure 5.6-9. Pin 1 of J11 is the square pin, which is also marked with a silkscreen "C". If
the jumper is placed across pins 1 - 2, the board is configured for the console module, which interfaces
with the MS900 controller. With the jumper across pins 2 - 3 of J11, the board is configured for the remote
module, which interfaces with the Model 971 sonar head. No other jumper settings are required.
The MS900 interface must be installed on a motherboard supporting AIB plug-ins, such as the AIB-4 or
the High Density Board (HDB-TX). Ensure the alignment dot, shown at the upper left of the figure below,
matches the dot on the motherboard. For more information about the HDB-TX board please refer to
Model 903-HD Video/Data Multiplexer User Guide P/N: 903-0612-00.
Front panel pin designations for the AIB-MS900 plug-in modules are given in the table below. The polarity
of the signal lines does not matter.
*The chassis pin is normally left open on the mating connector.
