NTI Manual Ethernet Switch
INTRODUCTION
The NTI ETH-4X1Manual Ethernet Switch was designed to enable the connection of on e of either four
DEVICEs to one NETWORK or one DEVICE to one of four separate NETWORKs using standard ethernet cable.
The user can control the ETH-4X1 manually to make a single connection active between one NETWORK and one
DEVICE at a time.
Available Options
• Manual Ethernet Switch with 2 user selectable connection ports rather than 4 (ETH-2X1)
• RS232 control to change connections in the ethernet switch via a serial stream (ETH-4X1-RS or
ETH-2X1-RS)
Glossary
NETWORK- Local Area Network (LAN)* , File server, DSL internet connection
CPU- Computer for user access
DEVICE- CPU or other data entry/acquisition equipment
COMMON- A DEVICE or NETWORK that is to be commonly connected to the selected NETWORK or DEVICE
(up to 4) through the ETH-4X1 Manual Ethernet Switch
SELECTABLE- Any NETWORKs or DEVICEs (up to 4) that will be plugged into the user selectable ports
(1-4) and connected to the COMMON through the ETH-4X1 Manual Ethernet Switch
*Note: The ETH-4X1 Manual Ethernet Switch cannot differentiate between LANs and modems. For the purposes of this manual
they will be considered to be identical.
Limitations
All SELECTABLEs must be of the same type (All NETWORKs or all DEVICEs)
If a DEVICE is connected to the "COMMON" port, then only NETWORKs may be connected to the user selectable ports.
If a NETWORK is connected to the "COMMON" port, then only DEVICEs may be connected to the user selectable ports.
