1.
The maximum distances specified by the manufacturer are listed below. These distances
are valid when using 22 or 24 AWG two twisted-pair unshielded cable. Shielded cable will
reduce distance to one-third of the table value. Please note that the proper wire, according
to National Electrical Code (NFPA 70), NFPA 30, and Automotive and Marine Service Station
Code (NFPA 30A) codes and regulations must be used when the modem is installed over a
hazardous location.

2400 baud - 5 miles
9600 baud - 2 miles
1200 baud - 10 miles

2.
Field wiring must be made with point-to-point wire or cable. If telephone lines are used, they
must be point-to-point (not go through any type of switching equipment).
3.
AC power for the SHM on the remote end should come from the same dedicated breaker
that supplies power for the data terminal (printer).
4.
Set both SHMs for DCE (switch located inside SHM).
Installation requirements for the SHMs are specified by the manufacturer. GASBOY will not be
responsible for any problems encountered if these units do not perform properly.
