Moxa Technologies warranty Connector Description, Powering on the UC-7122/7124

5. Connector Description

Power Connector

Connect the 12 to 48 VDC LPS or Class 2 power line to the UC-7122/7124’s terminal block. If the power is properly supplied, the Power LED will light up. The OS is ready when the Ready LED glows a solid green.

Grounding the UC-7122/7124

Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw to the grounding surface prior to connecting the power.

6. Powering on the UC-7122/7124

To power on the UC-7122/7124, connect the “terminal block to power jack converter” to the UC-7122/7124’s DC terminal block (located on the left side of the top panel), and then connect the power adaptor. Note that the Shielded Ground wire should be connected to the right most pin of the terminal block. Once the system is ready, the Ready LED will light up.

7. Connecting the UC-7122/7124 to a PC

There are two ways to connect the UC-7122/7124 to a PC: (1) through the serial console port, and (2) by Telnet over the network. The COM

settings for the serial console port are: Baudrate=115200 bps, Parity=None, Data bits=8, Stop bits =1, Flow Control=None.

ATTENTION

This product is intended to be mounted to a well-grounded mounting surface, such as a metal panel.

SG	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 here. Connect the SG
	wire to an appropriate grounded metal surface.

Ethernet Ports

The 10/100 Mbps Ethernet port uses RJ45 connectors.

SD Slot

The UC-7122/7124 have internal SD slots for storage expansion. To install an SD card, first use a screw driver to remove the SD slot cover to access the slot. The slot is located on the right panel of the UC-7122/7124. Plug the SD card directly into the socket, and then replace the SD slot cover. When an SD card is inserted, the system will create a directory called StorageDisk for accessing SD storage. To remove the SD card from the slot, press the SD card in slightly with your finger, and then remove your finger to cause the card to spring out partially. You may then grasp the top of the card with two fingers and pull it out.

USB

The UC-7122/7124 has one USB 2.0 host port located on the top panel for storage expansion. When a USB storage device is plugged in, the system will create a directory called StorageDisk for accessing the data stored on the device. If there is already an SD card in the SD slot, the

ATTENTION

Use the CBL-4PINDB9F-100 cable included with the product to connect a PC to the UC-7122/7124’s serial console port. Remember to choose “VT100” terminal type for the connection settings.

To use Telnet, you need to know the UC-7122/7124’s IP address and netmask. The default LAN settings are shown below. For first-time configuration, you may find it convenient to use a cross-over Ethernet cable to connect directly from the PC to the UC-7122/7124.

LAN 1	Default IP Address	Netmask
	192.168.3.127	255.255.255.0
LAN 2	192.168.4.127	255.255.255.0

system will name the newly created directory “StorageDisk2”.

Console Port

The serial console port is an RS-232 port that uses a 4-pin pin-header connector. The port is designed for serial console terminals, which are useful for viewing boot-up messages. Use the CBL-4PINDB9F-100 cable

Once the UC-7122/7124 is powered on, the Ready LED will light up. Use the following default login name and password to proceed. The defaults are:

Login: admin

Password: admin

Serial Ports

The serial ports use DB9 connectors for the UC-7122, and RJ45 connectors for the UC-7124. Each port can be configured by software for RS-232, RS-422, or RS-485. The pin assignments for the ports are shown in the following table:

DB9 Male (UC-7122)				Pin	RS-232	RS-422	RS-485	RS-485
1	2 3	4	5				(4-wire)	(2-wire)
				1	DCD	TxDA(-)	TxDA(-)	---
				2	RxD	TxDB(+)	TxDB(+)	---
				3	TxD	RxDB(+)	RxDB(+)	DataB(+)
				4	DTR	RxDA(-)	RxDA(-)	DataA(-)
				5	GND	GND	GND	GND
6	7	8	9	6	DSR	---	---	---
				7	RTS	---	---	---
				8	CTS	---	---	---

Reset

Press the “Reset ” button and hold it in for at least 5 seconds to load the factory default configuration. After the factory default configuration has been loaded, the system will reboot automatically. The Ready LED will blink on and off for the first 5 seconds, and then maintain a steady glow once the system has rebooted.

8. Configuring the Ethernet Interface

Please refer to the UC-7122/7124 User’s Manual for information on how to configure the Ethernet interface.
