19456 to 19695 (4C00H to 4CEFH)
19712 to 19951 (4D00H to 4DEFH)
19968 to 20207 (4E00H to 4EEFH)
20224 to 20463 (4F00H to 4FEFH)
RX offset/size information (Address 19456 to 19695 (4C00H to 4CEFH))
The areas to store the RX start number and number of points for each station No.
Buffer memory
addresses
Station No.1
19456(4C00H)
19457(4C01H) Station No.1
19458(4C02H)
Station No.2
19459(4C03H)
Station No.2
19694(4CEEH) Station No.120
19695(4CEFH) Station No.120
The offset and size of buffer memory address for each station number (other than a station number 0) can be calculated using
the following formulas:
• Offset buffer memory address = 19456 + (station number -1) × 2
• Size buffer memory address = 19457 + (station number -1) × 2
RY offset/size information (Address 19712 to 19951 (4D00H to 4DEFH))
The areas to store the RY start number and number of points for each station No.
Buffer memory

19951(4DEFH) Station No.120
The offset and size of buffer memory address for each station number (other than a station number 0) can be calculated using
the following formulas:
• Offset buffer memory address = 19712 + (station number -1) × 2
• Size buffer memory address = 19713 + (station number -1) × 2
