Page 3: Introduction
The whole system is user configurable to adapt to a wide range of payloads and requirements. Watson Industries also provides custom systems for special requirements. Our system design is modular and configurable for economical and quick adaptation to a wide variety of hardware configurations. - Page 4 In other words, the servo- control system ensures that the motion of the platform exactly matches that of the preset value in inertial space.

Page 5: Start-Up
When increasing errors are detected, the time constant is made longer so that the gyros are in more control of the attitude. This is done on the assumption that short-term errors are more likely to be caused by vehicle dynamics. Watson Industries, Inc. SMS-P233 Rev B 10/17/2017... -
Page 6: Pointing Angle
This is a last line of defense from a system failure, as it is fully independent from the other safety systems. Driving the mount away from this limit is not inhibited. Watson Industries, Inc. SMS-P233 Rev B 10/17/2017... -

Page 9: Sensor Package
As in all moving mechanisms there is concern about ice interfering with operation. The system has internal protection against damage from stalling the motors, but performance may be reduced. The system should be considered fragile. DO NOT APPLY LOADS OR FORCES TO THE PAYLOAD. Watson Industries, Inc. SMS-P233 Rev B 10/17/2017... -
Page 10: Connections
This product has one connector for all system connections. The user mating connector is Amphenol part number MS3106A-20-7S (included with the system). The connections are: Function Power Return +28 Volt Power No Connection RS-232 Transmit from SMS-P233 Signal Ground (connected internally to Power Return) RS-232 Receive to SMS-P233 No Connection Case Ground Power: This unit has an internal regulator to allow operation over a moderate voltage input range. -

“*” command from the interfacing computer. Such a change in setting can be made the default setting. Data transmission sent by the SMS-P233 can also be suppressed or restored by a “+” command from the interfacing computer. This change can be made the default setting. - Page 14 “Q”, and sometimes Escape or a Delete will interrupt the command and return to operation with the least disturbance to the system. All other unspecified characters such as carriage return, line feed and space are ignored by the system. Watson Industries, Inc. SMS-P233 Rev B 10/17/2017...
