In acknowledgment (response) packets, the operational code
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
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
equipment in the same manner. These are summarized as follows (all opcode values are
expressed in decimal form):
