Telenetics PE-LDM Limited Distance Modem Module

Pony Express modem modules are available for both dial and leased line applications, including all standards from Bell 202T (1200bps) to V.32 bis (14.4kbps). Other modules include a fiber optic line driver, a limited distance modem and an RS232/RS485 converter.

If the available power supply is limited (eg; a battery), the Pony Express module can be configured to fall into a "sleep" mode, or to completely power down, at times of inactivity.

These modules are also available to OEMs for integration into meters, controllers, RTUs, etc.

will work with you to embed a Pony Express modem module into your product. The modem can be installed in your existing rack chassis or will connect to your existing serial data interface. Because all of the Pony Express modules are fully interchangeable, a single design will enable you to install any modem in your product.

A Pony Express module is a part of every Telenetics? standalone and rack mount end user product ? See MIU, MIU/PowerPort and Myriad? products. These modules are also available to OEMs for integration into meters, controllers, RTUs, etc.

The various models provide a choice of DC power supply voltage (regulated and unregulated) and data interface (RS232 or TTL), and are designed to operate over a wide range of temperatures (-40?C to 85?C). If the available power supply is limited (eg; a battery), the Pony Express module can be configured to fall into a ?sleep? mode, or to completely power down, at times of inactivity.

Dial modems include an auto-reset feature, whereby the modem configuration, if lost, can be restored by making an incoming call. Most dial modems also include an autodial feature, whereby the closure of, say, an alarm contact can initiate an outgoing call to a host computer or a pager.

will work with you to integrate a Pony Express modem module into your product. If necessary, we will design and manufacture a custom motherboard for the Pony Express module, such that a modem can be installed in your existing rack chassis or will connect to your existing serial data interface. A single design will enable you to install any modem in your product.

MIU STANDALONE Modem

A Pony Express module is a part of our popular standalone products, the MIU and MIU/PowerPort. The MIU can even accommodate 2 modules, providing such combinations as a dial modem with fiber optic interface or an internal RS232 to RS485 convertor. Our standalone products are surge protected, will operate in extreme temperatures, and can be powered from a wide range of AC and DC voltages.


CUSTOM MOTHERBOARDS

will work with you to integrate a Pony Express modem module into your product. If necessary, we will design and manufacture a custom motherboard for the Pony Express module, such that a modem can be installed in your existing rack chassis or will connect to your existing serial data interface. A single design will enable you to install any modem in your product.



MYRIAD RACK MOUNT Modem Bank
The Myriad Rack Mount Modem Bank is an industrial grade 19? 3U chassis with slots for 18 modem cards.









METER MODEMS
For automatic meter reading, will integrate a modem into an electric, gas or water meter. Special features can be provided, such as off-hook detect and automatic call-in on power outage.

TECHNICAL SPECIFICATIONS:
Each Pony Express module is a fully functioning modem, complete with a 10-pin header for power and serial data, and an appropriate connector (eg; RJ11 or ST) for the analog or fiber optic data.

Serial Data: RS232 or TTL

Voltage: 5.5-9VDC unregulated or +5VDC?5% regulated

Current: 50 to 150mA, depending on model

Low Power Operating Modes:
Dial modems can be configured to fall into a ?sleep? mode, or to completely power down, at times of inactivity. In sleep mode, the inactive modem will draw less than 10mA and will instantly ?wake up? on an incoming ring (RI) or transmit data (TxD) signal.

In the power down mode, the current drain drops to 20?A and the modem will automatically turn on to full power within 400ms of receiving a DTR signal or an incoming call.

Auto Reset Feature
If a dial modem loses its configuration for any reason, the configuration is automatically restored by dialing the modem and allowing it to ring several times.

Auto Dial Feature

Most dial modems have the ability to automatically dial out to a stored phone number in the event of, say, an alarm condition.
