External Tamper Switch Connector
Optional GPS MMCX or u.FL Antenna (J14)
The optional GPS feature includes an antenna connector for an externally mounted
passive or active antenna. The 50 Ohm MMCX antenna connector (standard loading
option) is a vertical mount Molex 73415-2061, or equivalent. The 50 Ohm U.FL
connector (optional) is a vertical mount Sunridge MCBG-ST-00T, or equivalent.
Optional Input Power (J15)
Power is normally applied to through the barrel jack or through the GbE Ethernet
connector in either a Passive or 802.3af Compatible Power over Ethernet configuration.
The barrel jack can be replaced with a 2-pin header in a 1x2 configuration with
0.156-inch pin spacing as an ordering option. The mating connector is a JST
B2P-VH-FB-B. The mating connector pins are a JST SVH-21T-P1.1.

Optional Input Power Connector
Input Power Barrel Jack (J16)
Power is normally applied through the barrel jack or through the GbE Ethernet
connector in a Passive or 802.3af Compatible Power over Ethernet configuration. The
barrel jack should have the positive input voltage on the inner sleeve and ground on the
outer sleeve. The barrel jack inner pin diameter is 2.5mm. The input voltage
requirements are given in Section 3. The mating connector is a G/S SR2048A-R,
available from Jameco as part number 190538PS. The schematic symbol representing
this configuration is shown below.

Gigabit Ethernet Ports and Passive PoE Input Power (J17)
The Gigabit Ethernet Ports are available through a standard 8-pin RJ45 connector. The
connector also supports 802.3af Active and Passive Power over Ethernet. The power
inputs are diode protected to prevent back feeding with other power inputs. The Passive
PoE architecture is discussed in more detail in Section 1 and the input voltage
requirements are listed in Section 3.
