Connector Type Function
LAN RJ45 10 BaseT Ethernet connection to your “Local Area Network”. It runs at
10 MHz half or full duplex. See table 1.5 for the pin assignments. The
gateway “bridges” this LAN port to the WAN port.
E1/T1 RJ45
BNC
(NX-2E1/T1-B model) each of the two RJ45 connectors includes pins
for a balanced E1 or T1 serial stream. The wiring of these connectors is
shown in Table 1.4.
(NX-2E1/T1-U model) each unbalanced E1 serial port consists of a pair
of BNC connectors, one for the Transmit and the other for the Receive
signal.
GND Ground connection used for surge suppression. We recommend that you
connect this to an Earth Ground in order to reduce the possibility of
damage to the unit due to transients on external lines

RJ45
RJ45
10/100 Base T Ethernet connection to the “Wide Area Network”. If you
are connecting the Gateway to an AFAR Radio use the connector labeled
“Radio”. This connector includes voltage to power the radio directly
(see table 1.6). In all other cases use the connector labeled “Switch”
(table 1.5)
SYNC RCA Synchronization signal used to synchronize multiple AFAR radios, each
one connected to its Gateway.
Power Switchcraft DC Voltage to power up the gateway and optionally one AFAR radio
through the WAN/Radio connector.
