  • Page 39 Description: When the command V<CR> is received by the IC20/25 unit, the 8 character serial number will be returned in a text string terminated by <CR><LF>. The serial number for every IC20/25 unit is unique. If the command is not received in the proper syntax, e<CR><LF> will be returned. Torrey Pines Scientific, Inc.
