4.5.4 Global Response Operational Codes
In acknowledgment response packets, the operational code <OPCODE> field of the message
packet is set to 0 by the receiving devices when the message intended for the device is evaluated
as valid. The device that receives the valid message then exchanges the <SOURCE ID> with the
<DESTINATION ID>, sets the <OPCODE> to zero in order to indicate that a good message was
received, and returns the packet to the originator. This "GOOD MESSAGE" Opcode is one of
nine global responses. Global response Opcodes are common responses, issued to the M&C
computer or to another device, that can originate from and are interpreted by all Radyne Inc.
equipment in the same manner. These are summarized as follows all Opcode values are
expressed in decimal form:
