Configuring open collector
mode
CAUTION
The open collector configuration procedure
cannot be reversed.
Configuring the frequency/pulse or control outputs for
open collector mode requires jumpers on the RFT9709
to be cut. Once cut, the jumpers cannot be reconnected.
Do not cut jumpers unless you are certain your process
requires outputs in open collector mode.
• To configure the frequency/pulse output for
open collector mode, cut jumper JP2.
• To configure the control output for open
collector mode, cut jumper JP1.
