Product Manual
The rear panel RS232 communication port operates at 1200baud, and can be interfaced via any
terminal application. This port is limited to changing the output frequency. Selection of the
output frequency is made by using a proprietary protocol that sends a 10 digit ASCII character
string across the rear panel serial bus at a transfer rate of 1200baud, No parity, 1 stop bit. The
synthesizer firmware will not accept alpha or symbolic characters as part of the frequency data.
The Figure below demonstrates the messaging sequence:
To manually set a new frequency: type cntrl b; capital “E”; then type the10-digit frequency (ex:
0500000000), and press enter.
