USB to Serial Gateway - USG-2
Page 5
Features
NMEA 0183, RS422 and RS232 compatible
- this differential input is fully compliant with the NMEA 0183
standard specification.
ISO-Drive
TM
technology
- creates a driver unique to Actisense that has 1500 volts of isolation.
Isolated output (1500V)
- the ISO-Drive™ creates a completely “floating” output, making a safe connection to a
computer an easy task. The ISO-Drive™ output can safely transfer data to an NMEA 0183 device, or any other RS232/
RS422 device. The output automatically changes between differential, single-ended, RS232 and RS422 depending
upon the type of instrument it is connected to.
Isolated input (2500V)
- a floating receiver OPTO-isolated to 2500 volts protects the connected devices even
during the most extreme fault conditions.
Inputs & outputs fully protected against over voltage, ESD & short circuits
- electrical isolation makes
inputs and outputs robust enough to withstand many fault conditions and an electronic fuse will disconnect the USG-2
from any short-circuit until the fault is removed.
Fully encapsulated electronics
- the USG-2 PCBA is sealed inside a potted case, giving perfect protection to the
internal electronics from water and dust ingress.
High retention Type-B receptacle (USB 1.1, 2.0 & 3.0 compatible)
- there is naturally a lot of vibration in
the marine environment which can cause some connections to become loose over time. The High retention Type-B
receptacle on the USG-2 prevents the USB cable from vibrating loose.
Diagnostic LED’s show both Talker & Listener activity
- quickly and easily diagnose potential data
transfer issues.
Separate power LED
- immediately identify the power status of the USG-2.
Supports baud rates from 300 up to 230400 bps
- meets and exceeds NMEA 0183 baud rate requirements
while also covering the majority of RS232 or RS422 networking situations.
Bulkhead mount, with optional DIN rail mount kit
- makes mounting the USG-2 quick and easy in
professional installations.
Pluggable screwless connector with locking latch
- the spring loaded wire clamps and the locking latch prevent
wiring from being accidently pulled out or working loose over time due to vibration. The 2-part connector allows wires
to be connected quickly and easily, even in hard to reach locations.
Built-in strain relief on screwless connector
- maintain the integrity of your NMEA 0183 data wiring connections
by letting the USG-2 take the strain.
Software updates
The USG-2 does not have built-in firmware so it does not require updates. Actisense provides free access to the latest
USB drivers on the Actisense website,
