F9P output NMEA on UART1 at slower hz

I want to output NMEA on UART1 to my old Lexion Cebis display. I’ve tested the Cebis serial input at 4800 baud 1hz but that’s far too slow to keep up with 8 or 10 hz update like the rest of the F9P ports are doing. I suspect there’s some way to set the UART1 port to a slower output rate but as usual with u-Center, you have to go read the manual to figure it out. Does anyone know how?

I figured it out. In configuration view, messages, the number behind the port’s checkbox is a message frequency divider. So in my case, at 8hz base frequency, I set the UART port to divide by 8 to output at 1hz.
