Mode Modem m m m s s s s
Mode Mode
Modems can transmit data from an Open Processor to an operator interface over telephone
lines. Therefore, remote communication between the Open Processor and an operator
interface is possible using two modems—one at each end of the communication link. For
example, an alarm printer can be set up in a building manager's office to receive alarms from
an Open Processor that is in a remote location.
Modems may be used along with leased telephone lines to link remote Open Processors in a
networked system and to link remote Open Processors with a centrally located mass storage
device such as a personal computer running Insight for Personal Computers.
A modem approved for your application can be installed within the MBC or RBC enclosure. A
cable connects the modem's RS-232 port to the MMI/MODEM port on the Open Processor.
Refer to Figure 2-7. If you need more room for the modem, remove the literature pocket by
lifting up on the center of the pocket until the ends slide out from underneath the two tabs
on both sides.
NOTE:
For more information about modems approved for use with the Open Processor, contact
your local Siemens Building Technologies representative.
