1.4.1b Standard Connections - With a PC
IMPORTANT:
To install the HygroPro in a hazardous (classified) area,
see
Hazardous Area Wiring Connections on page 15.
Refer to Figure 4 on the next page and Table 2 below, and complete
the following steps to wire the transmitter.
1. Connect an RS485-RS232 converter (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 external system.
4. Trim any unused leads even with the outer cable jacket to remove
any bare wire and prevent accidental short circuits.
