Modem System Layout
Modem
Description
Modems are used for communicating with the SC when the distance or conditions do not
permit direct connection to the unit. Various types of modems can be used depending on the
maximum baud rate and connection method required. Modems used for dial-out to a bank
network require a dedicated phone line. Only Gasboy supplied modems are supported for use
with the CFN system.
Location
The modem should be located in an office-like environment. However, if this is not possible, it
should be housed in a protective enclosure. Do not install the modem in a hazardous location.
Modems supplied by Gasboy have an operating temperature range of 32 °F to 104 °F.
The AC Surge Protector, Power Conditioner, and the Voltage Regulator/UPS should
be installed independently and not combined between the AC outlet and the SC III.
IMPORTANT INFORMATION
AC Surge Protector Outlet Strip
Description
The AC Surge Protector Outlet Strip protects the SC and any equipment directly connected to
it (printer, monitor, and so on) from line surges, and filters out the Electromagnetic
Interference (EMI)/Radio Frequency Interference (RFI) noise.
Location
The AC Surge Protector Outlet Strip should be located within 6 feet of the SC. It must be
located in an area protected from direct contact with the weather. Do not install the Surge
Protector in a hazardous location.
