Section 3. Instrumentation Installation
3.3 Communication and Data Storage Peripherals
One or more peripherals (i.e., CompactFlash modules, modems, etc.) can be
mounted to the enclosure backplate (ENC12/14, ENC14/16, or ENC16/18
enclosures).
3.3.1 CFM100, NL115, or NL120
Connect the CFM100, NL115, or NL120 module to the peripheral port of a
CR1000 or CR3000 datalogger (see Figure 3.3-1). One CompactFlash card
fits in the CFM100 or NL115’s card slot. For the NL115 or NL120, Ethernet
communications is supported by connecting a 10baseT Ethernet cable.
3.3.2 COM220 Phone Modems
A phone modem enables communication between the datalogger and the
computer (with a Hayes compatible phone modem) over a dedicated telephone
line.
Mount the modem to the enclosure backplate as shown in Figure 3.3-2.
1. Mount the modem to the backplate using the four screws and nylon
grommets provided.
2. Connect the modem to the datalogger's I/O port with the SC12 cable
provided.
3. The telephone company generally provides surge protection, and a patch
cord that plugs into the RJ11C jack. If surge protection has not been
provided, the Model 6362 Surge Protector Kit can be installed to the
enclosure backplate. Connect the two terminals on the surge protector to
the "tip" and "ring" terminals on the modem as shown in Figure 3.3-2.
FIGURE 3.3-1. The NL115 connects to the CR1000’s peripheral port
allowing data to be stored on removable Compact Flash cards.
