hi ron, as far as i know, there's no yellow block that will sync up two different adc boards. you'd have to modify the yellow blocks to do this.
there are yellow blocks that will sync up a pair of ADC2x1000-8's, or a pair of ADC1x3000-8's. best, dan On Tue, Apr 30, 2013 at 1:06 PM, <[email protected]> wrote: > I want to know how to clock two ADC > boards on one ROACH (1) board so they > will be in sync with the ROACH clock > which is taken from one ADC board. > We have two ADC boards: an old iADC > ADC2x1000-8 board and an ADC1x3000-8 > adc083000 board.
