Flow Control Selection

Flow control signals regulate data flow for proper communication. To enable or disable the flow control, change the J2 FLW jumper according to Table 2-7. With flow control enabled, you can use either software or hardware protocols to control flow rates. You will need to remove the cover to change any jumpers. See “Changing Internal Jumpers” on page 2–8.
