file transfer Effected by number of repeaters and size of
packets
Slide 23
Calculating Polling Time Packet Overhead 15ms + Data
(Bits)/19.2k Baud Each Transmission Total Packet Turn Around Time
15ms+Data/19.2k+15ms (Ack) Retry = 50ms

Calculating Polling Time Polling Time Number of transmission in
message plus overhead Average retry rate
Slide 25
Polling Time Example Typical Read Message (10 Words) Header
15ms+Data/19200 Baud = 23ms Ack to Header 15ms Read 15ms+Data/19200
