The NTI ETH-4X1-GManual Ethernet Switch was designed to enable the connection between a common DEVICE or NETWORK and one of up to four DEVICEs or NETWORKs using standard Ethernet cable. The ETH-4x1-G is a switch that provides reliable physical signal separation between connected devices while supporting 10Base-T, 100Base-T, and 1000Base-T connections.
Be careful to route the cables away from any sources of magnetic fields or electrical interference that might reduce the quality of the signal (i.e. AC motors, welding equipment, etc.). • A 120V electrical outlet must be available close enough to the mounting location of the ETH-4X1-G to plug the AC adapter into. •...

INSTALLATION Connect the Cables Position the ETH-4X1-G such that the Ethernet cable from the COMMON , the AC adapter power cable, and the Ethernet cables from the SELECTABLEs can reach the ETH-4X1-G. Connect one end of an Ethernet cable to the COMMON (See Fig.1.) Connect the other end of that cable to the "COMMON"...
Plug-in and Boot Up Connect the AC adapter power connector to the 5VDC port on the ETH-4X1-G. Make sure the power connector is properly inserted. (See Fig. 3.) Plug the AC adapter into a power outlet. The status LED for SELECTABLE port 1 will illuminate indicating a proper power connection has been made.
RS232 Control RS232 (optional) enables the ETH-4X1-RS-G to be remotely controlled via RS232. To control the ETH-4X1-RS-G via RS232 the user has three options: • write a program that runs on a PC using the Command Protocol (below) • use the NTI Switch Control Program (page 8) provided on the CD •...
NTI Switch Control Program For Windows 9X, NT, 2000 AND XP The NTI Switch Control Program is an easy and powerful graphical program that controls NTI switches through an RS232 interface. The NTI Switch Control Program is included on the manual CD packaged with the ETH-4X1-RS-G. The NTI Switch Control Program can be downloaded to your computer by clicking on the link "Download NTI Switch Control Program"...
