●●Sorting number reading
■ Using auxiliary output and judgment output
Use 2 output lines to obtain sort numbers for 3 types. Output is performed in order beginning with the
current bank number, as follows, with subsequent sequences repeating this order.
Bank number Judgment output (black) Auxiliary output (red/black)
Current ON OFF
+1 OFF ON
+2 ON ON
■ Using communication function
Communication using RS232C is possible by connecting a dedicated cable (CVS-C2C) to the external
connection connector. With this communication, up to 15 types of sorted bank numbers can be read.
"255" is returned when sorting is not applied.
In addition, when performing external teaching, responses may take 3 seconds or longer.
Sorting number reading protocol
○ Command (53H) / Teaching (49H) / Checksum (63H): PC → CVS2
○
Response (06H) / Lower sort number (0 to 14/255) / Higher sort number (0/255) / Checksum: CVS2 → PC
* Checksum = Complement of 1 of (06H + Higher sort number + Lower sort number)
