1. Introduction
The Moxa UPort 1400-G2/1600-G2 Series comprises USB 3.2-to-serial converters that add four or eight
serial ports to a PC through the PC’s USB port. The UPort 1400/1600 is compatible with both new and
legacy RS-232 or RS-422/485 devices. These plug-and-play USB-to-serial converters are ideal for mobile,
instrumentation, and point-of sale applications.
In this manual, we refer to the products in the series collectively as the UPort 1400/1600-G2 Series, or
simply as the UPort. The UPort 1400/1600-G2 Series includes the following models:

Overview
The UPort 1400/1600-G2 Series is easy to install and use. After installing the drivers on your PC, connect
the UPort to your computer, plug in your serial devices, and you’re ready to go. Programming is not
required, and you do not need to worry about IRQs, configuring a board, power requirements, or connection
schemes.
The UPort 1400/1600-G2 Series complies with USB 3.2, 2.0, and 1.1 specifications, and meets the 5 Gbps
of Super-Speed USB 3.2. Connecting serial devices to your computer’s USB ports reduces the total cost of
ownership, investment in hardware, and long-term management and integration costs.
Most models of the UPort 1400/1600-G2 Series supports bus power and external power, and only the UPort
1650I-8-G2 and UPort 1650-8-G2-Hub converters require external power. You may refer to the Power
Input Supply section on page 9 for the applicable table.
When an external power adapter or power cord is used, the UPort will only draw 100 mA through the laptop
or workstation’s USB port.
Automatic Data Direction Control (ADDC) for
RS-485
Automatic Data Direction Control (ADDC) simplifies the management of 2-wire RS-485 half-duplex
connections, eliminating software interference. Thus, it is unnecessary to write extra code for Windows
applications to control the half-duplex protocol. ADDC intelligence is built into the UPort 1200/1400/1600
USB-to-serial converters that support RS-485 serial interfaces.
Automatic Recovery Data Communication
(ARDC)
Automatic Recovery Data Communication (ARDC) simplifies the auto recovery of data transmissions even if
a cable gets unplugged accidentally. Thus, you do not need to worry about reconfiguring complex settings to
ensure smooth data transmissions. If the USB cable is accidentally unplugged, just plug it back into the
same port, and the converter will automatically reconnect with the host and continue transferring data. This
feature not only reduces reconfiguration time but also the probability of data loss.

2. Product Installation
We recommend installing the UPort driver first before connecting the UPort to your computer’s USB port.
Hardware Description and Installation
NOTE
1. A maximum of 4 UPort converters can be connected to one PC host. Connecting more than 4 UPort
converters may strain system resources and potentially destabilize the computer.
2. We recommend connecting the UPort directly to your PC’s USB port.
3. Although your UPort supports USB 1.1, we recommend using a USB 3.2 host controller or hub for the
best and most stable performance.
Installing the driver before connecting the UPort to your PC. Some UPort models require an external power
adapter or cord; other models may support both external and bus power.

Adjustable Pull High/low Resistors for the RS-485 Port
The UPort uses DIP switches to set the pull high/low resistor values for each serial port.
To set the pull high/low resistors to 150 KΩ, make sure both SW 1 and SW 2 switches are in the OFF
position. This is the default setting.
To set the pull high/low resistors to 1 KΩ, make sure both SW 1 and SW 2 switches are in the ON
position.
To set the termination on, SW 3 should be set to the ON position.
You will need to unscrew the DIP switch cover to access the DIP switches.

Latching USB Cable User Guide
Here is how you can plug in Moxa’s USB cable into the UPort and computer securely.
The new latch USB cable comes with a latch on the side of a type A connector and a screw on the type B:
Always press both latches when plugging the connector into the receptacle on your computer.
Plugging in the USB cable to a host computer
Step 1: Press both latches.
Step 2: Plug in.

UPort 1400/1600-G2 Series User Manual
14
Plugging out a USB cable from a host computer
Step 1: Press both latches hard and make sure
they are pushed to the end.
Step 2: Plug out the cable 90 degrees horizontally to
the USB s
lot.
Caution on plugging in or out the latch connector
1. Always press both latches when plugging in or pulling out the cable.
2. If the type A connector doesn't come off smoothly, DO NOT pull the cable out by force as it will
deform the hook on the connector, and you may not be able to use the cable again. Try again by
pushing the latch hard and shaking the connector from left to right gently.
NOTE
The latch cable locks to most computer USB slots, however, there may be some slots designed with a
slight difference, preventing the latch from locking to your computer USB slots perfectly.
Plugging in an USB cable to the host computer
The screw on the side of type B connector is for fixing the cable firmly to the UPort. Please remember to
swivel bolt after plugging in and before pulling out the connector.
Step 1: Plug in type B connector.
Step 2: Swivel the bolt about 5 rounds.

UPort 1400/1600-G2 Series User Manual
15
Pulling out an USB cable from the host computer
Step 1: Swivel the bolt about 5 rounds until it is loose.
Step 2: Pulling out the type B connector.
Ground Screw
All the product’s certifications are performed with ground-screw wiring. We strongly recommended to wire
the ground screw before any operation takes place. With without wiring to a ground screw, please consider
the product’s environment and prevent any possible surge that may damage the product or cause
interference to the communication.
Reset
The reset button is on the front panel of the UPort, and the button is to restart the UPort when necessary. If
it is required to reset the UPort to default settings, you will need to access the function in the driver
property. Please refer to Reset to Default in the Configuring UPort section below.

NOTE
If you require more screws, please contact your reseller or Moxa sales representative.
If the UPort models on the rackmount are connected directly to a computer or have an external power
source from a power adapter, it is fine to place an 8-port or 4-port model on either the right-hand or left-
hand side. If you would like to leverage the UPort 8-port hub model’s USB bus output power to include other
UPort models, the UPort 8-port hub model needs to be placed on the right-hand side of the rackmount tray
(left-hand side from the rear view). However, please note it is necessary to use a USB 3.2 compatible cable
to ensure enough power.
