RS-485 to RS-232 Converter
An RS-485 to RS-232 converter is required for communication between the SC III, and a
modular Profit Point or a tank monitor. It converts the format of the data from RS-232 to
RS-485 and vice versa.

Logger Printer
Description
A printer can be used as a logger for providing hard copy printouts of activities at the site. It
can be directly connected to the printer port of the PC or to one of the SC’s serial ports. If
connected to the PC printer port (LPT 1), the cable length cannot exceed 25 feet.
Location
The printer should be located in a clean, office-like environment. Do not install the printer in a
hazardous location. Printers supplied by Gasboy have an operating temperature range of 32 °F
to 104 °F and 10% to 95% relative humidity (non-condensing). Locating the printer in a dirty
environment may cause premature failure of the printer.
