Figure 3.7 Two INCORRECT Connections
Connection to Multiple Controllers via RS485
Up to 127 controllers can be connected to each desktop reader via RS485 bus. The
correct RS485 connection method has been briefly introduced in the section entitled
“RS485 Bus Extension”. Here are the details to connect multiple controllers via
RS485, shown as Fig. 3.8. The terminal 10, 11 and 12 on the main module should be
connected to the upper level controller’s terminal 10, 11 and 12.
