6. Configuration
6.1 S1 Bitswitch Function
S1-1 On = 100 ohm terminator connected across the TCC-Link lines
Off = No terminating resistor.
Note:- Only one terminating resistor should be enabled per network
S1-2 On = Auto Restart
Off = Start in the OFF condition
Note:- S1-2 overrides the normal auto restart feature
S1-3 to S1-8 Set the address of the unit; S1-3 = MSB : S1-8 = LSB
The address is the binary value of S1-3 to S1-8 plus 1.
(all switches off = 1, all switches on = 64)
