3.4.3 Tx/Rx LED
The Tx/Rx LED located on the front panel above the RS232 port lights whenever activity is
detected on either of the instruments communications ports.
3.5 RS232 Service Port
The front panel port acts as an extension to the 70 Series IED service port (P1). This port can be
connected to a terminal or a PC running a terminal emulator program, such as Hyperterminal.
Through this connection it is possible to view log messages, set the date/time, and transfer files.
Refer to the M87x User Manual for further information.
When transferring files using the front panel service port the display is not updated. A message
indicating a file transfer is in progress is displayed at this time.
When connecting the Service Port to a PC, a straight through cable, either 9-pin to 9-pin or 9-pin to
25-pin, is required. A null modem cable is not required.
