2400 baud RS232. 8 bit data, no parity, 1 start bit, 1 or 2 stop bits.
Serial data is sent to the unit on one of the parallel channel select pins (P0). It is very important that
the unit does not ‘decode’ switch bounce in ordinary operation as a command string, or spurious re-
writing of the EEPROM will result. For this reason the user must send the 16 character string
ENABLESERIALMODE to fully enable the serial command mode before sending any of the command
strings listed below. Command mode is disabled on power down, or on reception of a # character.

SINGLE mode does not store the N value in EEPROM. Therefore the unit is inoperative
after a power down until either another valid SINGLE command is received, or mode is
changed by a GOCHAN, SETPAR or SETSER command. SINGLE mode is intended for
frequency agile applications.
