OVERVIEW

If you have a large polled network that uses 1200or 1800-bpsspeeds and want to upgrade incrementally to 9600 bps, then the 9600 FP Modem is for you.

This industrial-grade,leased-linemodem features two modes of operation: Fast Poll Mode for 9600and4800-bpsuses and Bell 202T Mode for up to1800-bpsspeeds.

Because it’s backward compatible with 202T devices (as well as ITU-TV.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-suitedfor unmanned locations.

You can use the 9600 FP Modem for 4-wire,full duplex

or 2-wirehalf-duplexoperation over avoice-basedleased line. It works with bothvoice-bandconditioned 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—23ms—inFast 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-dutysurge 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-TV.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-glanceconfirmation 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-232interface.

The Modem Rack II has slots for 16 modem cards and a power supply module (which is included) and can be mounted

in a standard 19" (48.3-cm)rack. It’s 7" (17.8 cm) high and

 

 

10" (25.4 cm) deep. In back, the rack has 16 DB25 female

 

 

connectors and 16 telco connectors.

 

 

Because the rack‘s front panel is hinged, you can add and

 

 

remove cards from the front of the unit without disturbing

 

 

the DTE and line connections at the rear of the rack.

 

 

 

 

The front panel is also translucent, so you can easily view

 

 

the LEDs on the front of the cards. To access a card’s test push

 

 

button to perform loopbacks, just lower the front panel.

 

 

When you order a modem, you’ll receive the Standalone

 

 

or Rackmount Card 9600 FP Modem, a leased-linecable, and

 

 

a user‘s guide. The MD1980A-DCalso includes a shielded DC

 

 

power cable.

 

 

With the rack (RM421A), you get a 115-VAC,60-Hzpower

Why Buy From Black Box?

Exceptional Value. Exceptional

Tech Support. Period.

Recognize any of these situations?

You wait more than 30 minutes to get through to a vendor’s tech support.

The so-called“tech” can’t help you or gives you the wrong answer.

You don’t have a purchase order number and the tech refuses to help you.

It’s 9 p. m. and you need help, but your vendor’s tech support line is closed.

According to a survey by Data Communications magazine, 90% of network managers surveyed say

that getting the technical support they need is extremely important when choosing a vendor. But even though network managers pay anywhere from 10 to 20% of their overall purchase price for a basic service and support contract, the technical support and service they receive falls far short of their expectations—andcertainly isn’t worth what they paid.

At Black Box, we guarantee the best value and the best support. You can even consult our Technical Support Experts before you buy if you need help selecting just the right component for your application.

Don’t waste time and money—callBlack Box today.
