RS-485 Serial Port Configuration On TLS-450/TLS-450PLUS

1. The jumpers should be set as shown in Figure 7 above:
a. J7 (determines if serial interface is RS-232 or RS-485) should be set on
pins 1 and 2. Notice the 1 on the right side of the J7 box. That is pin 1.
b. J8 should connect both pins.
2. The other jumpers should be set as shown.
