The TS-7800 implements a sleep mode that allows the board to go down to 200 micro amps. This power off the TS-7800 while the AVR waits for the specified time to wake up the board. It can make sleep for 5 seconds by running this:

root@ts7800:root# ts7800ctl -s 5 This only allows the board to sleep for seconds, not smaller units of time. It is however wake up immediately from an

external interface by driving DIO_04 or ISA_B32 high. This sleep functionality will only work if power is fed in through the +5V connector on the TS-7800 itself. If you are using a PC104 device like the TS-POE100 or the TS-BAT10 then you would have to cut the +5V pins on PC104 and bring it down to the TS-7800 power connector in order to use the sleep functionality. Otherwise the board can be powered through PC104 with no modification. 

The Display data has two sub-function “Line” and “Scroll”.

i) The Line sub-function reads a long characters string from a file as an input and convert into lines (for each 24

characters).

ii) The “Scroll” sub-function displays the input string and data onto the LCD display panel line by line, where the keypad plays to scroll lines up- down.
