External Mercury Modem

The basic external modem assembly includes a modem mounted in a
Mercury 800 series case, main battery plate, Hubbell fittings and an
Alkaline Disposable or Receptacle Power Pack.
The external modem is very versatile and can be configured with
numerous options. The first choice is the type of enclosure, the options
available are:
Mini Case
800 Series Case (Standard Option)
1200 Series Case

When considering the type of enclosure, keep in mind that each
installation may require different configurations. If the Modem
Expansion Board is to be used for additional communication ports and
there is a requirement for barriers, the 1200 Series Case or the
Hennessy Aluminium Case may be the only options available.
Next the type of power supply must be considered. Included in the
basic modem is either the Alkaline Sealed Pack or the Alkaline
Receptacle Power Pack. Other power options are available, they are:
40-1447 Lithium Power Pack
40-2107 DC Power Supply Kit
N/A Solar Panel
