README FILE

The following is an extract from the GMS-2 Users Manual for the operation of 
the RS-232 Option with the GMS2LINK software.

The GMS-2 can communicate to a computer via the Serial Interface Adaptor 
(S.I.A.) which supplies RS-232 data to the host computer.  The S.I.A. uses the 
optical output port at the bottom of the GMS-2 console and converts the 
optical signals to an RS-232 data stream for the Host computer.
The S.I.A. is powered by an internal PP9, 9 volt battery that is turned on by 
the connection of the RS-232 interface into the Host computer when the 
computer operating.

Operation

To connect the S.I.A. to the GMS-2, make sure the white dot on the optical 
connector is facing upwards and then screw the two screws into the GMS-2.

The RS-232 on the GMS-2 operates at 2400 baud rate.

The HOST Menu on the GMS-2 is used to set up the RS-232 output to the 
computer.  See page 7 of this Manual for details regarding the Host Menu.

GMS2LINK.EXE

The software program GMS2LINK.EXE is used on the Host PC to set-up and 
communicate with the GMS-2.  The program will allow for receiving and 
storing the downloaded data to a file.  It should be noted that the S.I.A. 
needs to be installed in COM1 of the computer and the battery connected.

The program has a pulldown menu system with the following groupings:
FILE    Open File - to open a valid file name to store the 
		    data.
	Save File - to store data into the open file.
	View File - to view the data in a particular file.
	Exit      - to exit out of the program, the ESC key has the 
		    same result.
COMMUNICATION       Allows Communication with the GMS-2.
		    The GMS-2 controls what is being sent to the Host
		    computer.  If Tx is set to ON (with Rx set to OFF) in the 
		    GMS-2 then the 'R' and 'D' keys on the computer keyboard 
		    can be used (for READ and DUMP respectively).  
		    The Host Menu on the GMS-2 may be changed while in 
		    Communication Mode.
		    To get out of the Communication menu, use the ESC 
		    key.  This will automatically save the data to the open 
		    file.
UTILITIES           Insert Header - allows for the insertion of a line 
		    header into the open file whenever required.  You 
		    must first escape out of the Communications Menu.

When a file is open its name and path will be displayed below and to the right 
of the Menu line.  The word SAVING will be present when data is being 
transferred to the file.
