5.19 To Output a File’s Content to RS232 Output on Card Initialisation
Should it be useful to output a command line to the RS232 Output 1, for example to start the
output of data from a sensor, it is possible to write this command line to a file called
STARTUP.TXT. This content of this file may be set to output each time the SD card is initialised.
To enable output of file STARTUP.TXT, the following SETUP.TXT command line is available:
STARTUP=u

If u = Y , the content of file STARTUP.TXT will be output on the RS232
Output 1 each time the memory card is initialised.

If u = N , STARTUP.TXT will not be output
Note:

File STARTUP.TXT must be located in the root directory on the card.

File STARTUP.TXT may contain any characters with values 0 to 255

The data contained in file STARTUP.TXT is not recorded by the SpaceLogger
5.20 Logic Inversion of the Received Signal
The SpaceLogger.S10 is RS232 and TTL/CMOS* logic compatible.
To assist with input of TTL/CMOS data, the SpaceLogger.S10 may be configured to invert the
logic of the received signal on RS232 Input 1. By default the input is RS232 logic compatible.
To set the SpaceLogger.S10 to invert the logic of the received signal command
RX_INV is used.
RX_INV = Y Logic inverted on received signal on RS232 Input 1
RX_INV = N Signal not inverted on RS232 Input 1
The default setting is RX_INV=N.
