FEATURES
• Dual mode: Use in both 1200-/1800-bps
and 9600-bps environments.
• Ideal for collecting data from modem
banks in large polled networks.
• Connects to 4-wire full duplex or 2-wire
half-duplex over voice leased line.
• Surge-protected line interfaces.
• Poll-response time of 23 ms.
• Configure easily with DIP switches.
• Standalone and rackmount card
versions available.
These modems work in extreme conditions and provide
super-fast polling times for multidrop applications.
OVERVIEW
If you have a large polled network that uses 1200- or
1800-bps speeds and want to upgrade incrementally to
9600 bps, then the 9600 FP Modem is for you.
This industrial-grade, leased-line modem features two
modes of operation: Fast Poll Mode for 9600- and 4800-bps
uses and Bell 202T Mode for up to 1800-bps speeds.
Because it’s backward compatible with 202T devices
(as well as ITU-T V.23 modems), you can extend the life of
your existing hardware and worry about upgrading later. For
this reason, it’s the perfect transitional modem for multidrop
automation applications in industrial settings. You can use
the 9600 Modem, for instance, to communicate with Bell
202T remote modems that perform well enough now but
will eventually be replaced with 1200/1800 models.
Typical applications are to use the 9600 FP Modem
for system control and data acquisition (SCADA) or for
communicating with utility substations or industrial facilities.
Because the modem requires no human intervention for it to
operate, it’s particularly well-suited for unmanned locations.
You can use the 9600 FP Modem for 4-wire, full duplex
or 2-wire half-duplex operation over a voice-based leased line.
It works with both voice-band conditioned or unconditioned
leased line and pilot wires, and features selectable
asynchronous data rates of 9600 and 4800 bps in Fast Poll
Mode and 0 to 1800 bps in Bell 202T Mode.
The modem features a DSP chip set and powerful line
equalizers. These enable reliable operation over long
runs of copper wire and leased telco lines that don’t meet
conventional specifications and offer limited performance.
Designed specifically for outdoor use and harsh environments,
the 9600 FP Modem works where other modems don’t,
permitting more drops per polled link than any other modem.
Digital signal processing (DSP) technology gives the
modem its power. With its fast turnaround—23 ms—in Fast
Poll Mode, the 9600 FP Modem ideally suits systems that
require fast response, short training time, and low
throughput delay.
It’s available in an AC or a DC standalone version or a card
version for use in our Modem Rack II. The rackmount version
occupies only one rack slot.
Both standalone and card versions feature heavy-duty
surge protection that guards the line interface and can
withstand a surge voltage up to 15 kV.
To configure the 9600 FP Modem, simply set a few DIP
switches. Because no PC is required, it’s easy to set up in the
field. Configure the modem for your host DTE interface
and network topology; select your mode and (if necessary)
whether you’re connecting to a Bell 202T or ITU-T V.23
modem; then choose the transmitter output level and receiver
dynamic range.
Troubleshooting is also easy. An LED control display on the
9600 FP Modem gives you at-a-glance confirmation of modem
operation, and a local and remote test push button enables
you to perform analog or digital loopbacks.
For attaching DTE devices, the modem’s back panel has
a DB25 connector on an RS-232 interface.
The Modem Rack II has slots for 16 modem cards and a
power supply module (which is included) and can be mounted
