External Ports
The MK2200 has the following external ports:
•
RS485
•
Ethernet / Bias-T (Power-over-Ethernet)
•
Power
•
Headphones
•
Scanner/printer (RS-232, powered).
RS-485
The RS-485 (10-conductor RJ-45 connection) half-duplex interface is also called the Multidrop LAN since it
can connect several MK2200s in a LAN network environment. See
Figure 2-9 on page 2-13 . These devices
are all connected to a single pair wire (i.e., transmit and receive share the same two wires).
Ethernet/Bias-T
Wired Ethernet: Power through AC Outlet
The Ethernet / Bias-T (10-conductor RJ-45) port accommodates Ethernet data connection. The MK2200
receives power through the Symbol approved power supply.
Wired Ethernet: Power through Power-over-Ethernet
The MK2200 supports Power-over-Ethernet (POE), Symbol Technologies' proprietary
Bias-T functionality. An Ethernet (10/100Base-T) cable connected to the Ethernet/Bias-T port provides both
data communication and power to the MK2200.
