6.1.4 Connecting Multiple TP-410 Units via the RS-485 Bus
You can connect up to 15 TP-410 units via the RS-485 bus with control from a PC
or serial controller. To connect up to 15 TP-410 units via RS-485 (see Figure 11 ):
1. Connect the RS-485 terminal block of the first TP-410 to the RS-485
terminal block of the second TP-410, and so on (see Section 5.3
2. Set each TP-410 address number to be a unique number (see
),
connecting all the TP-410 units via the RS-485 terminal blocks.
Section 7.1
3. On the first and last TP-410 physical devices on the RS-485 bus, set the
RS-485 termination DIP-switch ON (terminating the RS-485 line at 120
Ω,
