5 Installing the IG502

5.1 DIN rail mounting and dismounting

5.1.1 DIN rail mounting

The DIN rail mounting plate is attached to the rear panel of the IG502 as shown below:

Installation steps are as follows:

1. Select the installation location of the equipment and ensure that there is enough space;

2. Snap the upper part of the DIN rail holder onto the DIN rail, and rotate the device at the lower end of the device with a little force upwards as shown in arrow 2 to snap the DIN rail holder onto the DIN rail, and confirm that the device is reliably mounted onto the DIN rail, as shown in the figure below:

  

5.1.2 DIN rail dismounting

The method of dismounting the IG502:

1. As shown by arrow 1 in the figure below, press down on the device to give clearance at the lower end of the device to disengage from the DIN rail.

2. Turn the device in the direction of arrow 2 and move the lower end of the device outwards at the same time. Lift the device upwards after the lower end is detached from the DIN rail to remove the device from the DIN rail.

5.2 Wall mounting

The IG502 can be mounted using a wall mounting kit, which needs to be purchased separately. There are three wall mounting options and the steps are shown below for each:

Wall mounting method 1: Mount the wall mounting kit on the upper and lower panels of the IG502 (lug mounting)

Step 1: Fix the wall mounting kit to the upper and lower panels using the screws

When the fixing is completed, it is shown in the figure below:

Step 2: Once the wall mounting kit is secured to the device, use screws to secure the device to the wall or cabinet

Wall Mounting Method 2: Mount the wall mounting kit on the rear panel of the IG502 (back lugs)

Step 1: Screw the wall mounting kit to the rear panel of the device

When the fixing is completed, it is shown in the figure below:

Step 2: Once the wall mounting kit is secured to the device, use screws to secure the device to the wall or cabinet

Wall Mounting Method 3: Install the wall mounting kit on the upper and lower panels (large surface lugs) of the IG502

Step 1: Screw the wall mounting kit to the top and lower panels of the device

After the fixing is completed, it is shown in the following picture

Step 2: Once the wall mounting kit is secured to the device, use screws to secure the device to the wall or cabinet.

6 Connector Description

6.1 Ethernet Interface

The IG502 has 2 RJ45 Ethernet ports that support 10M/100M adaptive rates.The RJ45 pins are described below:

Pin	10M/100M
1	TX+
2	TX-
3	RX+
4	-
5	-
6	RX-
7	-
8	-

6.2 DC Input/Serial Port

The IG502 supports 12-48V DC power supply. Plug the adapter terminal into the DC port of the IG502 and then connect the power adapter. When the PWR power indicator lights up long then it means the device has been powered up normally.

IG502 has 2 serial ports, one serial port supports RS485 and one serial port supports RS-232 or RS-485 mode.

When the interface combination is RS232+RS485:

Device node corresponding to RS232 serial port: /dev/ttyO1

Device node corresponding to RS485 serial port: /dev/ttyO3

When the interface combination is RS485+RS485:

Device node corresponding to RS485-1 serial port: /dev/ttyO1

Device node corresponding to RS485-2 serial port: /dev/ttyO3

The power supply and serial port use 7PIN terminals, and the interface pins are described below:

PIN	Name	Definition
1	V+	Power Positive
2	V-	Power Negative
3	TXD or 1A	Serial RS232 send or first RS485+
4	RXD or 1B	Serial RS232 acceptance or first RS485-
5	GND	Serial RS232 signal ground
6	2A	Second RS485+
7	2B	Second RS485-

6.5 USB interface

The IG502 provides a USB 2.0 Host interface, which is mainly used for expanding storage devices.

IG502 supports USB storage device hot-plugging. It will mount all the partitions automatically.IG502 will mount all the USB storage device partitions under the path /mnt/usb/sda1, and only the first partition of the USB storage device will be mounted.

ATTENTION:

Before disconnecting the USB mass storage device, remember to enter the sync command to prevent data loss. When you disconnect the storage device, exit from the /mnt/usb/sda1 directory. If you remain in /mnt/usb/sda1, the automatic uninstall process will fail. If this happens, type umount /mnt/usb/sda1 to manually unmount the device!

6.6 Micro SD

The IG502 has a Micro SD card. The SD card does not support hot plugging and needs to be operated when the power is off. It will automatically mount all partitions.

The IG502 will mount all partitions of the micro SD memory card to the /mnt/sd path. The naming format of the mounted folder is mmcblk0p<num>, where <num> is a number from 0 to 9.

6.7 SIM card slot

The IG502 is equipped with two Micro SIM card holders for cellular communication, located on the upper panel. The SIM card installation does not support hot-plugging and needs to be operated when the power is off.

6.8 Antenna Interface

Identification	Name
GPS	GPS antenna
WLAN	WAN Antenna
AUX	AUX Antenna (Auxiliary Antenna)
ANT	ANT (Main Antenna)

6.9 DIP switches

As shown in the above figure, the 4-digit dip switch can be used to realize the enable selection of the pull-up/down resistors of A/B of RS-485 interfaces COM1 and COM2 respectively. Enabling the pull-up/down resistors of A/B of the RS-485 interface can improve the anti-interference ability of the RS-485 bus and solve the problem of garbled characters caused by interface chip compatibility.

Identification	Description
PU1	ON: Enable pull-up resistor for COM1 RS-485 A OFF: Disable pull-up resistor for COM1 RS-485 A (default)
PD1	ON: Enable pull-down resistor for COM1 RS-485 B OFF: Disable pull-down resistor for COM1 RS-485 B (default)
PU2	ON: Enable pull-up resistor for COM2 RS-485 A OFF: Disable pull-up resistor for COM2 RS-485 A (default)
PD2	ON: Enable pull-down resistor for COM2 RS-485 B OFF: Disable pull-down resistor for COM2 RS-485 B (default)

Note: Enabling the RS-485 pull-up/down resistors, however, reduces the maximum number of access devices allowed on the RS-485 bus.

6.10 Factory Reset Button

There is a reset button for restoring the system to the factory, and the procedure for restoring the factory device using hardware is as follows:

7 Power and Environmental Requirements

Input Voltage	12-48 VDC (dual pin terminals, V+, V -)
Operating Power Consumption	250mA@12V
Operating Temperature	-25-70°C (-13-158°F)
Storage Temperature	-40-85°C (-40-185°F)

8 Access to IG502

Use the following default IP address to connect to the IG502.

Step 1: Interconnect the IG502 to the PC

Insert one end of the cable into any of the IG502's network ports as shown in the figure below, and the other end into the computer's network port, and set the computer's IP address to the same network segment address as the device interface.

Step 2: Network and system management of IG502 via web

IG502 supports the WEB interface management based on IEOS, which is a set of network management and system management programmes developed by InHand and running on Linux system, and IEOS can provide web interface service. Taking the network cable network port inserted into the LAN port as an example, the device login information is as follows:

Login: https://192.168.2.1

Initial login account: adm

Initial login password: check the nameplate on the device panel for the initial password information

The following figure shows an example of using a WEB connection:
