 Telenetics
introduces the latest addition to the family of industrial grade,
temperature hardened Modems, Model Telenetics MOT202T
modem. This 0-1800 bps leased telecom line or private wire modem is a
pin-for-pin, form, fit and function replacement
for the Motorola/UDS RM16M202T and 202T modem. Telenetics recently signed a
manufacturing license with Motorola and we are now delivering this new
product line.
Telenetics had to change some of the older
chips for newer analog filters which gives new life to a world class modem.
With these new changes we can offer an even a better unit - now with wider
voltage and temperature range.
Features
such as built-in diagnostic, anti-streaming, multi-power inputs (115 to
240AC, 12 to 125VDC) and heat/cold rated operating range capabilities make
this modem a must for industrial applications.
Telenetics has designed
modems that work in "remote" remote sites with very low failure rates. These
devices work where other modems roll over and die. When a service call to a
remote site can mean an all day trip these modems are the ideal solution.
To service the growing need for
efficient, reliable data communications in the harsh environments of
"remote" remote sites and industrial facilities.
Telenetics
has developed a family of data communications products
that can operate from various AC & DC power supplies and survive high
surge levels and extreme heat and cold. All this without compromising the
performance expected from state-of-the-art communications devices.

Telenetics MOT202T moem is a direct
replacement for the very popular 30-year-old (a defacto standard)
UDS-Motorola 202T modem design that Motorola acquired through the
purchase of Universal Data Systems

The
Telenetics
MOT202T
is a Frequency Shift Keyed (FSK) modem
which is designed for asynchronous operation at 0 to 1800 bps with good line
conditioning, or 0 to 1200 bps asynchronous operation on unconditioned
lines. The modem provides half duplex communications on 2 wire private lines
or full duplex communications on 4 wire private lines, and is ideal for use
in multipoint networks.
The
Telenetics MOT202T modem is a single printed circuit card enclosed in a new
compact size housing. The unit features an integral anti-streaming
protection option which prevents network Tie-ups by incorporating a delay
timer that will disconnect a modem, if it remains in transmit mode longer
than a selectable period of time. The 202T also features strap options for
Request to-Send/Clear to Send Delay timing, Transmit Carrier, local Copy
Squelch, Turnaround squelch, Soft Carrier Turn Off, Carrier Detect Level,
Carrier Detect Delay, and Test Generator Baud Rate Select. These strap
options allow the user greater control of the modem, for his individual
application.
The
Telenetics MOT 202T
modem features built-in diagnostic and anti-streaming capabilities. The
anti-streaming capability prevents a modem from remaining in the transmit
mode when the modem is not actively transmitting data. The diagnostic
features allow the user to verify transmitted and received data.
The
modem is designed to be interchangeable between the Universal Data Shelf
multiple modem enclosure (RM16M series) and the stand alone modem enclosure.
By removing the modem card and attaching the optional front panel, the modem
can be directly inserted into the Universal Data Shelf. With this feature, a
data-communications facility can be easily upgrade front multiple standalone
enclosures to a centralized rack without the expense and trouble of
purchasing new modems. Telenetics had to change some of the older chips for
newer analog filters which gives new life to a world class modem. With these
new changes we can offer an even a better unit - now with wider voltage
choices and a temperature range.

Test Operate Switch DL (Digital Loopback);
When the switch is in the ST position, the received data is looped
back into the transmitter and the data is transmitted to the remote end.
The modem must be in the 4 wire mode.
TTP (Transmit Test Pattern): When the switch is in the TTP
position, the transmitter is forced ON and transmits the date from the
dot pattern generator to the COMM Line. The RS-232 interface lines to
the transmitter are not active (RS, CS, TD).
DATA: The switch must be in the DATA position for all normal
data transmission Indicators
RS (Request to Send): is illuminated when the RS line is high
(ON)
CS (Clear to Send): ON when the CS line is high (ON)
CD (Carrier Detect): ON when a carrier is detected by the
modem receiver.
RD (Receive Data): On when data is received, decoded, and
furnished to the terminal equipment. RD is also ON when the receive cats
line goes into a space condition, OFF in a mark condition.
TD (Transmit Data): Responds in the same manner as the RD LED,
but only when data to be "transmitted" is furnished to the modem.
However, the LED may be on when the DTE is disconnected.
TM (Test mode): Active when Test switch is in any test mode.
The indicate' will blink OFF/ON when errors occur in Self Test mode
POWER: ON when power is applied
