EIA-422 Mode (EtherLite 2 or 162 only)
To operate a port of the EtherLite 162 EIA-422 in EIA-422 mode, set the
port’s EIA-422 ENABLED switch to the up position. Set the TERMINA-
TION (422 ONLY) switch to the down position. This switch connects a
120 ohm, 1/2 watt resistor across the input signals.
EtherLite 2 EIA-422 ports are hard-wired to EIA-422 mode, and have no
termination installed. Pinouts are shown in the table below.
Note: 2-wire multidrop configuration for EIA-422 is not supported.

*EIA-232 signals on EtherLite EIA-422 only
EIA-485 Mode (EtherLite 2 EIA-485 only)
EtherLite 2 EIA-485 ports are wired for half duplex multiple drop EIA-
485 mode and have no termination installed.

Overview
Digi EtherLite serial port servers connect asynchronous serial ports to
10Base-T or 100Base-T Ethernet connections. Most EtherLite servers
support speeds up to 115 Kbps or 230 Kbps on all ports simultaneously.
This table shows all EtherLite models and their capabilities.
EtherLite Models
* Individual ports are configurable as either EIA-232 or EIA-422.
** 115 Kbps is not attainable on all ports simultaneously on the EL-32.
Ethernet Cabling Requirements
The EtherLite unit requires an unshielded twisted-pair (UTP) 10Base-T
or 100Base-TX Ethernet connection. In order to maintain radio frequency
emissions compliance, use EIA/TIA 568-compliant Category 4 or Cate-
gory 5 for 10Base-T and Category 5 only for 100Base-TX.
Installing the EtherLite Software
Install the hardware before you install the device driver software. Follow
the software installation instructions on the Access Resource CD.
