The FSN tag is a powerful tool that assures sequential information framing and is especially useful where commands require more than one message packet The full handshake acknowledgment involves a reversal of source and destination ID codes in the next message frame followed by a response code in the lt OPCODE gt field of the message packet from the equipment under control If a command packet is sent and not received at its intended destination a timeout condition can occur because the packet originator does not receive a response message On receiving devices slaved to an M amp C computer the timeout delay parameters may be programmed into the equipment in accordance with site requirements by Radyne Corp prior to shipment or altered by qualified personnel The FSN handshake routines must account for timeout delays and be able to introduce them as well Global Response Operational Codes In acknowledgment response packets the operational code OPCODE field of the message packet is set to 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 lt SOURCE ID with the DESTINATION ID sets the lt OPCODE gt 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 amp C c
