CN5: SyncBus Connector CN5 is a proprietary 16-pin header that is used for synchronizing RTD data acquisition and signal processing boards. The SyncBus Connector is a 2 x 8, 0.1” spacing right-angle connector. The lane assignments are shown in Table 5. A typical mating connector is an FCI 65043-029LF.
USB. When there is no transmission from the bus, the RX is switched to the RS232 TX input. RTS and DTR pins are not used and are pulled to GND with 10k. CTS is not connected. SYNC35104HR RTD Embedded Technologies, Inc. | www.rtd.com SYNC25104HR/...
