A776 (B780) Programming Guide

After the right transit symbol are immediately the four characters of the check serial #, followed immediately by the ten 
characters of the account number. These would be bitwise encoded as:

0 0 1   0 0 1 0 0  (check #, four characters) 

and  0 1 0   0 1 0 1 0  (account #, 10 characters)

then stored in the other three words of the table entry using:

0x1B 0x73 0x24 0x4A 27 

 

0x1B 0x73 0x00 0x00 28 

 

0x1B 0x73 0x00 0x00 29

t22137–632t001 6042202o927540 

 

2754 is the check serial # 

 

6042202 is the account #

To load the third table entry, which starts at word 30, the transit number 2137–632 would be stored in the first two 
words of its table entry using this string of commands:

0x1B 0x73 0x22 0x13 30 

 

0x1B 0x73 0x76 0x32 31

After the right transit symbol are four characters to skip, a seven digit account number, two characters to skip, and 
finally a four digit check serial #. The final character to skip need not be encoded. These would be bitwise encoded as:

 

1 0 0   0 0 1 0 0  (skip four characters) 

 

0 1 0   0 0 1 1 1  (account #, seven characters) 

 

1 0 0   0 0 0 1 0  (skip two characters) 

 

0 0 1   0 0 1 0 0  (check #, four characters)

then stored in the other three words of the table entry using:

0x1B 0x73 0x84 0x47 32 

 

0x1B 0x73 0x82 0x24 33 

 

0x1B 0x73 0x00 0x00 34.

Present contents of the exception table can be examined using the read NVRAM command:

0x1B 0x6A k

which reads and returns word k in NVRAM. When the exception table is full, a new entry can replace an older, less 
frequently used entry, by merely rewriting the words for that table entry.

Value of m:

Writes m bytes of data to the user data storage flash page at the address specified. The printer waits for m bytes of data 
following the 3-byte address, addr.

If any of the memory locations addressed by this command are not currently erased, the command is not executed.

 The printer disables interrupts while writing to flash. Any command that cause data to be written to flash should be 
followed by a 50 Msec delay to allow significant time for the write operation.
