Data Rate Switch
EIA-485 ROTARY DATA RATE SWITCH
Although the switch in Figure 5 displays stops for only 3 data
rates, every rate in Table 1 has a stop. Count the clicks to
determine the five unlabelled rates. At one stop clockwise past
the 5.00 position, you get 10 Mbps. The next clockwise stop
selects the 78 kbps rate — then 156 kbps, 312 kbps and 625
kbps in turn — until the 1.25 (Mbps) label is reached.
