Compact serial device server with DB9 port and Ethernet jack

ALSEYE

ALSEYE NPort 5150 1 Port RS-232/422/485 Serial Device Server

SKU CH-YMJZ-CMGRB

Compact serial device server converts one RS-232/422/485 port to Ethernet for networked equipment integration

  • Compact size simplifies installation in tight spaces
  • Real COM/TTY drivers support Windows and Linux systems
  • Multiple operation modes via standard TCP/IP interface
  • Configure units through Windows utility, Telnet or web browser
  • Adjustable pull high/low resistors optimise RS-485 signal integrity

Compact Serial Device Server

The ALSEYE NPort 5150 is a single-port serial device server that connects legacy RS-232, RS-422 or RS-485 equipment to an Ethernet network. It suits engineers and system integrators who need to add remote access to industrial controllers, data loggers or building-automation gear without rewiring existing serial cabling.

Bundled Software and Drivers

Windows and Linux Real COM/TTY drivers let legacy applications treat the networked port as a local COM or TTY device, removing the need for code changes. A Windows configuration utility supports batch setup of multiple units, while SNMP MIB-II, Telnet and a web browser interface give administrators several ways to manage devices centrally.

Installation Notes

The small form factor fits tight enclosures and DIN-rail mounts with minimal clearance. Adjustable pull high/low resistors on the RS-485 port simplify bus termination for long cable runs. The main difficulty is matching serial parameters such as baud rate, parity and flow control on both the server and the attached device; mismatches will prevent communication until corrected.

Questions about this item

Will the DB9 serial connector or the 5150's internal flash need periodic replacement?

The DB9 port is a passive connector with no wear-out mechanism, and the 5150 stores its configuration in non-volatile memory that does not require scheduled replacement.

What limits throughput first when the 5150 runs at 485 speeds continuously?

The serial line rate set for the RS-485 port determines the maximum sustained throughput; the 5150 forwards data at that configured baud without internal buffering bottlenecks.

How much heat does the 5150 produce when powered all day?

The 5150 draws low power from its external supply and runs without a fan, so it stays cool to the touch during continuous operation.
