Figure 2-6 Wireless Installation with VSmart Indoors
NOTE:
It is recommended to fill out an Integra Site Survey (M00-2027) before doing a
wireless Petro-Net installation. This can help identify possible interference problems.
2.2.9 Communication
After determining the range of the modems, you can permanently install and wire the remote station modem.
Polarity is critical with all RS-485 communications. Petro-Net Terminal 1 goes to pin 8 on the modem, and
Terminal 2 goes to pin 2 on the 9-pin modem connector. Both modems are wired the same. Use the supplied
Petro-Net connector; connect the black wire to #1 on the Petro-Net Terminal and the white to the #2
Terminal.
IMPORTANT: RS-485 (Petro-Net) polarity is critical!
