1 Introduction
EMG101 Gateways are components of Symbol Technologies Wireless Controller System. An EMG101 Gateway
links to wireless 802.15.4 electronic shelf label tags. It installs in minutes anywhere a CAT-5e (or better) cable is
located.
The EMG101 Gateway ships with two single-band 2.4GHz 802.15.4 radios. The radios are configured for redundant
operation. If the currently operating radio fails, the gateway will automatically activate the second radio.
The EMG101 Gateway is approved under MODEL: EMG101.
Symbol recommends the EMG101 Gateway receive power and transfer data through the same CAT-5e (or better)
Ethernet cable using a Symbol Power Injector. The Power Injector ((Part No. AP-PSBIAS-2P2-AFR) is an 802.3af PoE
injector. For information, see
Power Injector System.
A separate power supply (Part No. PWRS-147376-01R) is also available if you do not wish to use a Power Injector.
This standard power supply just supplies power to the EMG101 Gateway’s power connector and does not converge
power and Ethernet within a single cable connection.
