power source
Follow these instructions to install the PC Interface adaptor:
1. Plug the AC/DC power converter into the adaptor. Or, if desired,
install a 9-volt battery (not included) in the battery compartment on
the back of the adaptor (see
Figure 2-1
, page 5).
• Battery life is approximately 11 hours when the transmitter
operates at 38.4 kilobaud.
• To remove the battery compartment cover, push down on the
cover and slide it in the direction indicated by the arrow. After
installing the battery, put the battery compartment cover securely
in place on the back of the adaptor.
For use in the European community, the Micro Motion PC Interface is
CE compliant only when used with a power supply that is filtered
against electromagnetic interference. Use of a battery or the power
converter in the ProLink kit meets this requirement. To order a
replacement power converter, see
Appendix A
.
2. Set the selector switch on the adaptor to the center position, which
shuts off power to the adaptor.
3. Plug the adaptor into a serial port on the personal computer, as
illustrated in
Figure 2-6
. If necessary, install the supplied 25-pin to
9-pin converter between the serial port and the PC Interface adaptor.
4. Set the selector switch on the adaptor to the appropriate position:
• To use the Bell 202 standard, set the switch to 202.
• To use the RS-485 standard, set the switch to 485.
5. With a battery installed or the AC/DC adaptor plugged into the
adaptor and a power supply, and with the selector switch set to the
202 or 485 the adaptor is ready for use. The red light labeled "Power"
on the adaptor should be lit.
