UC-7101 Hardware User’s Manual Hardware Introduction ATTENTION This function only takes effect when the user directory is working correctly. If the user directory has crashed, the kernel will automatically load the factory defaults. Real Time Clock The real time clock in the UC-7101 embedded computers is powered by a lithium battery. We strongly recommend that you get help from Moxa’s technical support team to replace the lithium battery.
3 Chapter 3 Hardware Connection Description In this chapter, we show how to connect the UC-7101 embedded computer to the network and to various devices.
UC-7101 Hardware User’s Manual Hardware Connection Description Wiring Requirements This section explains how to connect the UC-7101 to serial devices. You should heed the following safety precautions before installing any electronic device: y Use separate paths for power wiring and wiring for devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.
UC-7101 Hardware User’s Manual Hardware Connection Description ATTENTION This product should be mounted on a well-grounded mounting surface such as a metal panel. SG V- V+ SG: The Shielded Ground (sometimes called Protected Ground) contact is the left most contact of the 3-pin power terminal block connector when viewed from the angle shown in the figure at the left. Connect the SG wire to an appropriate grounded metal surface.
UC-7101 Hardware User’s Manual Hardware Connection Description Connecting to a Serial Device Connect the serial cable between the UC-7101 and the serial device(s). The two serial ports (P1 and P2) use male DB9 connectors, and can be configured for RS-232/422/485 by software.
UC-7101 Hardware User’s Manual Hardware Connection Description Installing a Secure Digital (SD) Memory Card UC-7101 The SD slot is located on the right side of the UC-7101 enclosure. To install an SD card, you must first remove the protective cover to access the slot, and then plug the SD card directly into the slot. Step 1: Use a screwdriver to remove the screws holding the SD card slot’s outer cover. Step 2: After removing the cover, insert the SD memory card into the slot.
