The simplest link between your HART protocol smart transmitters and any computer with a standard RS-232 port is the MicroLink™ modem.  No batteries to replace or configuration switches to set.  Modem power is taken from both DTR and RTS to increase compliance with some low power serial ports. MicroLink conforms to FCC part 15, class B and is CE certified.
