Master Clock Connections
The CH1000 is capable of acting as a master clock. As such it can be set up to synchronize Sapling RS-
485 based slave clocks. The RS-485 port is located inside the CH1000 cabinet (See Figure 16). This port is
wired as shown below. Pins 4 & 5 provide RS-422 communications to the Sapling clocks. (Feature not
available at time of manual release. Contact factory to confirm when feature will be supported).
