Moxa's driver for x86 computing platforms support ARM-based platforms. Compile the driver using the following Linux commands to enable the use of UPort 1100 Series USB-to-serial converters with an Arm-based platform. You can download product drivers from Moxa website.
You can find the COM ports of the UPort converter in the Windows Device Manager. The COM ports are listed in the Windows Device Manager after you successfully install the UPort driver. You can check the properties of the ports just like you check the PC’s built-in COM ports. To change the serial interface settings for a UPort converter in Windows, do the following:
(1) Click on the Multi-port serial adapters setting in the Windows Device Manager.
You can change settings such as the COM port number and serial interface type (e.g., from RS-232 to RS-485).
(2) Right-click on the UPort converter and select Properties
(3) In the Properties box, click on the Ports Configuration tab
(4) Select the port configuration entry and click Port Setting
(5) In the Port dialog box, modify the converter settings
(6) Click OK
(1) Open the Device Manager on host computer/PC.
(2) Connect Moxa UPort to host PC.
(3) In Device Manager, expand the Universal Serial Bus Controllers tree. Native COM port is listed as Communications Port - COM1.
(4) Right-click on Communications Port-COM1 and select Properties.
(4) In the Properties window, go to port setting (Port Configuration tab)
(5) For the Port Number field, select COM2 for your Native COM Port and click OK.
(6) Click on the OK button in properties window. Native COM port number should change to COM2 on Device Manager.
(7) Connect Moxa UPort 1100 Series to host.
(8) Open Device Manager on host and check the Ports (COM & LPT) option. Moxa USB Serial Port for your UPort should be set to COM1.
(9) If the Moxa USB Serial Port for your UPort is not set to COM1, follow the procedure detailed in steps 1 to 7 to change it to COM1.
The recommended maximum number of UPort converters connected to one host computer is 4. Connecting more than 4 UPort converters could overload the system resources and potentially destabilise the system. Moxa's UPort driver does not restrict the number of devices that can be connected to a computer or notebook. Do keep in mind power requirements of the devices connected. Ensure there is sufficient power.
