Overview
About the Lantronix EDS4100
The EDS4100 (also written EDS 4100) combines an Ethernet terminal server and a multiport device server in one metal enclosure, so four serial devices at one location can be networked, accessed and managed through a single unit. Lantronix positions it for integrating edge equipment such as medical devices, kiosks, POS and retail terminals and security equipment into enterprise networks, where encrypted access and a familiar management interface matter.
It has four DB9M serial ports: two RS-232 and two software-selectable RS-232, RS-422 or RS-485, each at 300 bps to 921.6 Kbps with CTS/RTS or XON/XOFF flow control. An Intel XScale IXP420 at 266 MHz with 32 MB SDRAM runs Lantronix Evolution OS. Security includes SSL v3, SSH v2, AES 128-bit, 3DES and RC4 encryption, password protection and IP filtering. Configuration uses a Cisco-like CLI, a built-in web server, XML, SNMP v2 with RS232 MIB, or DeviceInstaller, and Com Port Redirector provides virtual COM ports.
Power options remove the need for separate power converters: 802.3af PoE, 9-30 VDC on a barrel connector or 42-56 VDC on a screw terminal, at 5.4 W. Order ED41000P0-01 without a power supply or ED41000P2-01 with a universal AC supply. The unit operates from 0 to 55 C and measures 3.81 x 17.65 x 12.7 cm in a metal enclosure with removable wall mounts.
Key capabilities
- Four serial ports
- Four DB9M ports: two RS-232 and two selectable RS-232, RS-422 or RS-485, each running at 300 bps to 921.6 Kbps.
- Three power inputs
- Power from 802.3af PoE, 9-30 VDC on a barrel connector or 42-56 VDC on a screw terminal, so it runs from a PoE switch, a low-voltage DC source or a 48 VDC feed.
- Encrypted management
- SSL v3 and SSH v2 with AES 128-bit, 3DES or RC4 128-bit encryption, plus password protection and IP filtering to block unauthorized hosts.
- Cisco-like CLI
- A Cisco-like command line, built-in web server, XML configuration and SNMP v2 make the EDS4100 easy to script and manage alongside network gear.
- Surge and ESD protection
- 2 kV common-mode and 1 kV differential surge protection on power, 15 kV ESD protection on serial ports and 1500 VAC Ethernet isolation.
How to choose the right EDS4100 part number
Both EDS4100 SKUs are the same four-port device server; they differ only in what is in the box. ED41000P0-01 ships without a power supply, for sites that will power it from 802.3af PoE, a 9-30 VDC source or a 42-56 VDC screw-terminal feed. ED41000P2-01 includes a 100-240 VAC international power supply with regional adapters. Both include DeviceInstaller and Com Port Redirector software and a quick start guide. ACC-520-0182-00 is a 12VDC 10W wall-cube supply sold separately.

EDS4100 FAQ
How many RS-485 ports does the EDS4100 have?
Two. The EDS4100 has four DB9M serial ports: two dedicated to RS-232 and two that are software-selectable between RS-232, RS-422 and RS-485. All four run from 300 bps to 921.6 Kbps.
Can the EDS4100 be powered by PoE?
Yes. It is IEEE 802.3af PoE compliant. It can also run from 9-30 VDC on the barrel connector or 42-56 VDC on the screw terminal. Typical power is 5.4 W, or 450 mA at 12 VDC.
What is the difference between ED41000P0-01 and ED41000P2-01?
ED41000P0-01 has no power supply included and suits PoE or existing DC power. ED41000P2-01 includes a 100-240 VAC international power supply with regional adapters. The device server hardware is the same.
What security does the EDS4100 support?
SSL v3 and SSH v2, with AES 128-bit, 3DES and RC4 128-bit encryption, MD5, SHA-1 and Base-64, password protection and IP filtering. These protect both serial data sessions and management access to the unit.
What is the operating temperature of the EDS4100?
The EDS4100 operates from 0 to 55 C (32 to 131 F) at 10% to 90% humidity and can be stored from -40 to 70 C. It is housed in a metal enclosure with removable wall mounts.
