The SAGE



 host software installed on a personal computer allows for 

data retrieval and analysis.  Communications with the LTC-MAP 2130 

must be established in order to download data to the PC or upload 

configuration information to the terminal.  Communication between the 

PC and the monitor can be established: 

• 

Directly via the front panel serial port and a null modem cable 
to a personal computer running the SAGE



 host software. 

NOTE: SAGE



 host software must be installed on the PC for 

proper communication to take place.  The front panel serial 

port does not support dumb terminal operation. 

• 

Over phone lines using an optional modem installed inside the 

monitor. 

• 

Over phone lines via a phone multiplexer installed in the 

control house and connected to several LTC-MAP 2130 

monitors. Refer to Document No. 70061MP for detailed 

information on the phone multiplexers available from Reuter-

Stokes, Inc. 

CAUTION: The serial port and the modem cannot function 

simultaneously. When using the serial port for communications, the 

internal modem (if installed) must be disconnected at J8; otherwise 

the serial port will not function.
