Installation and Operation
1 .2 Netlink Network Communication Module Overview
1
C1 (H1) and C2 (H2) Inputs (J12 & J16)
These are the connectors for the current sensors . Only an
NL2 or NL4 current sensor should be plugged into this con-
nector . The sensors have a range of +/-20A and are typically
used to monitor battery discharge current . See section 1 .3 .4
2
Event 1 Input (J14)
This is the connector for the Event1 input . This input will
accept 9-30VDC to initiate an event alert . This input will only
indicate an active or inactive condition and will not measure
the voltage level . See section 1 .3 .5
3
ADC1 Input (J15)
This is the Analog to Digital Converter (ADC) input, which
acts as a voltmeter . It accepts 0-30V and is used to mea-
sure positive or negative system voltages which are common
grounded with the Netlink board . The ADC cable wiring must
be routed away from high voltages . See section 1 .3 .7
4
Input V+ & V- (J1 & J3)
This is the power input for the Netlink board . This input ac-
cepts 8 to 30VDC ONLY from any power supply . If the Netlink
is being used in an FPA series system, an NS2 board is
re-
quired
to convert the AC power to DC power . See Appendix 2 .
Note - The voltage input of the Netlink must be connected
directly to the DC1 output or to the V+/V- fastons (if present)
of the power supply .
5
Ethernet Connection (SK1)
This is the RJ45 jack for the network connection . The ethernet
cable is plugged into this jack . See section 1 .3 .2
i
NOTE: This port does not accept PoE power . Do not con-
nect PoE to this port .
6
Status LED Indicators (D2, D3, D4)
These LEDs indicate the status of the Ethernet link to the
Netlink board .
LED Indicator:
Green (LINK)
Lights when Netlink is connected to a network
Red (DATA)
Flashes during data transfer
Blue (SYS)
Lights when the Netlink is fully booted up and
running . During the bootup process, this LED may flash
on and off several times . The Netlink will not be able to be
accessed until this LED lights steady . Older NetLink boards
may have a Yellow SYS LED .
7
External Temperature Sensor
This connector is for the external temperature sensor and is
only present on the NL4 board . See section 1 .3 .6
8
Dual ADC Jumper (J9)
This jumper enables "Dual ADC Mode" when using the Netlink
with an NS2 board . If an NS2 board is not being used, leave
this jumper OFF .
The following are basic Netlink board descriptions . Refer to the appropriate section for more detailed information .
NOTE - There are two generations of NetLink NL2/NL4 boards . Generation 2 can be identified by the red PCB color, while
Generation 1 uses a green PCB . Use the appropriate illustration above .
