The standard ROM and the service ROM are checked. The SSP data (ASCII) to be stored is as follows: circuit is also checked. D1FFE0H ~ D1FFEFH: Model name code (example: ER-A770. The following menu is displayed. The cursor position is highlighted. Display is made up to 00H of data.) key and key to move the cursor.
RS232 I/F PWB are compared. Check content Since the RS232 on the main PWB of the ER-A770 is fixed to The operation of the clock crystal of CKDC9 is checked. CH1 and CH8, that in the ER-A7RS must be set to CH2 ~ CH7.
The above check is repeated four cycles. RS232 I/F Diagnostics Data transfer check The loop back data (256 bytes) of 00H ~ 0FFH are used for CHANNEL Check ← Display when channel present data transfer check. The baud rate is set to 38400BPS. CH1 = exist! CH2 = exist! Timer check (RS232 on board timer)
CH1 Check. 3-6. Liquid Crystal Display Diagnostics 8) CH7 Check The ER-A770 LCD display is checked. Check content The test program displays the patterns in the following sequence. The check procedure, the display, and the terminating procedure Every time when the ENTER key is pressed, the next pattern is are the same as CH1 Check.
Reversed pattern of the above display. 3-8. SHARP Retail Network Diagnostics The SRN test is performed. To perform this test, the following composition is required. ER-A770 Terminal resistor Branch (trunk) cable (only for data transfer test) The outermost peripheral of the LCD’s active area is displayed The following menu is displayed.

During operation, the individual counter channel counts down from CLK/TRG0 the preset time constant value. In counter mode operation the counter ZC/TO0 decrements on each of the CLK/TRG input pulses until zero count is reached. Each decrement is synchronized by the system clock. For CLK/TRG1 DATA counts greater than 256, more than one counter can be cascaded.
