The second device seeing the "}" would process the request and send the message within the double

quotes, with the ASCII hex (<CR>) replaced with the actual hex characters (R 1 1 0D) to the third

device (which may be an FSR IT-R4S). Since the message to the third device hasn’t a drop

preamble it would handle the relay request.

Responses

Responses from the downstream device will just be passed up; the addition of the drops will only

make for more complex and harder parsing for the control system. The characters will be assembled

into messages and sent up as they come in. If a message doesn’t have a terminator (<CR>, <00>,

etc.) the receiver will time out after 1.5 seconds of receiver inactivity and send that message up.
