Heading information request
Describe which display or control equipment needs the requested information. Provide the equipment identification and its input documents so the supplier can respond to a defined requirement.
Installation context
Supply the planned mounting location and any arrangement drawings available. Ask for the proposed compass installation document and the conditions your reviewer needs to assess for that position.
Output documentation
Request the exact output and connection specification for the proposed unit. Have the interface reviewer compare that information with the receiving equipment documents before agreeing to a connection arrangement.
Compare compass documents together
Keep the proposed compass identity with the receiving equipment documents and the installation sketch. Ask for clarification where a connection or output description is incomplete. If the receiving unit changes, provide the revised input document and have the interface reviewer compare it with the compass proposal before selecting the equipment arrangement.
