Remote Maintenance
Remote Maintenance is an
optional
application for the MERLIN LEGEND Intuity
system. While it is possible to use the “pass through” capability of the System
Programming and Maintenance Utility (SPM) for remote maintenance, this usually
requires operator assistance to do so. The Remote Maintenance option provides
simpler operation and a higher level of service.
The Remote Maintenance Modem must be connected to Serial Port 2 (COM2). If
Serial Port 2 (COM2) is already in use, you must do the following:
1. Move the device (if any) connected to Serial Port 2 (COM2) to the first
available port on the Multi-Port Serial Card. See device specific
instructions elsewhere in this chapter.
2. Readminister the application formerly using Serial Port 2 (COM2) to use
the serial port now connected on the Multi-Port Serial Card.
3. Connect the Remote Maintenance Modem to Serial Port 2 (COM2).
