1.4.1.3 Standard Connections with a PC for field software upgrade
Refer to Figure 9 on the next page and Table 2 below, and complete the following steps to wire the transmitter.
1. Connect an RS485-to-USB adapter (customer-supplied) to an available serial port on the PC.
2. Push the female connector end of the factory-supplied cable into the mating male connector on the transmitter
module. Make sure the pins are properly aligned. Then, secure the connectors together by sliding the metal
sleeve on the cable over the connectors and turning it clockwise until it is tight.
3. Using the flying leads at the other end of the factory-supplied cable, connect the transmitter to the
RS-485-to-USB adapter. The cable shield should be connected to the common terminal.
4. Trim any unused leads even with the outer cable jacket to remove any bare wire and prevent accidental short
circuits.
