WARNING
If you connect or disconnect the serial cable with power
applied to the module or the serial device on the other end
of the cable, an electrical arc can occur. This could cause an
explosion in hazardous location installations. Be sure that
power is removed or the area is nonhazardous before
proceeding.
IMPORTANT
If 24 V Common is not referenced to earth ground, we
recommend you use an RS-232 isolator, such as Phoenix
PSM-ME-RS232/RS232-P (Cat. No. 1440-ISO-232-24), to
protect both the XM module and the computer.
