Installation: Networked ESD Constant
Monitor System
General: Installing the AEI Network Monitoring System consists of mounting and plugging in the Network Monitoring Hub (NMH) and the AEI-9202DM ESD monitors that will be connected to it. The AEI-9202DM units will be on the workbenches where the operators can plug in their wrist straps and bench connections. The location of the NMH should be chosen so that you can run the cables from the AEI-9202DM's to it and be able to connect to your local area network. You connect multiple NMH units the same as multiple computers to your Ethernet network switch/hub/router. See the diagrams below Cable Lengths: The maximum distance for the Ethernet network cables is about 300 feet. The maximum distance for the ESD monitor cables is about 3000 feet. You should avoid running either of these cables near electric motors or other machinery that will create electrical noise in the wires. Network: The NMH has a 10/100 Ethernet port on it to connect to your LAN. Standard Ethernet cable is used to connect the NMH to your LAN. The NMH will be accessed by it's IP address. The default address is 192.168.0.101. If this must be changed to operate on your network, call your network installer or administrator. They should know what IP addresses can be used on your network. The default Username is "AEI" and the default Password is "NMS". ESD Monitors: The cable used to connect the AEI-9202DM's to the NMH looks like standard phone cable but it must wired correctly. Cables you would buy at retail for your home phone will NOT work. Stock length cables can be provided. If custom cables need to be made, they need to be 4-conductor cables and have the same color code and pin connections on both ends. Many "phone cables" for home use have the connections reversed. Some specialized knowledge is required to install and configure the AEI Network Monitoring System. You may be able to just plug in and operate a small installation but if special cables must be made or the network configuration must be changed, you should call a network professional. The diagram below shows the connections for a single Network Monitoring Hub (NMH) and a single computer
 
1. Mount the AEI-9202 in a
convenient place on the workbench using the Velcro supplied with the
unit or the optional mounting bracket. The units are
frequently mounted on the underside of the workbench to keep them
out of the way.
2. Plug the power adaptor
into the 9202 and into a grounded outlet. Both LEDs should
turn red and the buzzer should sound. The ground in the outlet
is an important part of the system and should also be connected to
the ESD common point ground. The outlet and the common point
ground can be located at any convenient place on the workbench.
3. Plug the bench cable into
the back of the unit and connect it to the bench mat. It
should
be connected to the opposite side of the mat from the mat ground
connection. The BENCH LED should turn green.
4.) plug data cable into
monitor and attach to NMH
NOTE: The continuous
monitors are designed to work in the static conductive range of
matting but work well with static dissipative tri layer
matting (like our and
UltraComfort or
UltraTough) or dual layer matting with a conductive bottom layer
and static dissipative top layer (like our
ElectraTherm ESD rubber matting). If using tri layer static
dissipative matting the unit (and ground connection from the
matting) must make contact with the conductive
inner layer of the esd mat. To insure this contact use either our
push
and cinch or mat snap kit. Many customers hardwire the bench
cable to the fastener (the unit is supplied standard with an
alligator attachment) or use the optional
snap attachment available at a cost of . . .
4. Plug a wrist strap into
the front of the unit and put it on. The OPERATOR LED should
turn green. If it doesn't, touch the wrist strap to the common
point ground. If the OPERATOR LED turns green then the wrist
strap was not making good contact with the Operators wrist.
5. If incorporating with the
network monitoring system: Plug the grey flat cable
into the back of the ST-020 and into the AEI NMH. Verify that
the NMH status is the same as the LED on the front of the ST020.
Note: A calibration / test
unit is available for the ST-020. Simply plug the ground cable
into the common point ground and the operator cable into the
OPERATOR input. The LED should be red. It should be
Green when you press the "test" button.
