Cost-effective
industrial-grade
CommFront
offers
a range of cost-effective industrial-grade RS232/RS485/RS422 to TTL
converters, which are suitable not just for industrial but also
commercial applications.
Why industrial-grade?
Just as there are many differences between industrial- and
commercial-grade computers, industrial- and commercial-grade TTL converters differ in many ways, such as the level of
circuit protection, temperature range and noise tolerance. Most
importantly, true industrial-grade converters, such as CommFront's, require rugged
components and reliability-engineering designs to withstand heat,
vibration, shock and other environmental factors, therefore, they
are much more durable than commercial-grade converters.

Hassle-free auto-turnaround feature
CommFront's RS485 to TTL
converters come with the auto-turnaround feature. Upon sensing a
"start bit" (a logic high "Mark" to low "Space" transition) from its
TTL data transmit line (TxD), the RS485 transceiver circuit will
automatically change the data direction so that the RS485 side is in "listening" mode, thus reducing the chance of data
collusion. The auto-turnaround feature eliminates the need of using flow
control and/or software drivers; therefore, it is very useful for
half-duplex RS485 communications.
Note: Auto-turnaround feature is not applicable to full-duplex communications such as RS232, RS422,
and TTL, because full-duplex communications consist of two channels:
TX (Transmitting) and RX (Receiving), and both channels can operate
simultaneously.

Plug-and-play with full circuit protection
CommFront's
RS232/RS485/RS422 to TTL converter products come with the
auto-sensing and self-adjusting features, which automatically adjust
baud rate, parity, stop bit and other COM port parameters to the
devices that they are connected to.
The converters are hot-pluggable and are equipped with 600W surge
protection, 15kV ESD protection, and additional circuit protection,
thus making the devices highly reliable and truly plug-and-play.

ALL-IN-ONE rugged terminal block with
selectable 120-Ohm and 5VDC input
Most of our TTL converters
come with an ALL-IN-ONE rugged terminal block professionally
designed for different requirements, such as the selectable 120-Ohm
terminator jumper, which is important for reducing noise and
reflections when the RS485/RS422's distance exceeds 660ft (200m) or when
the baud rate is above 19.2kbps; the external 5VDC input for compact
RS485 / RS422 to TTL converters; and the TX, RX, and GND inputs for shielded twisted-pair
cables such as CAT-5e cables.

SGS/TUV
strictly-certified
superior-quality products
CommFront's RS232/RS485/RS422 to TTL converter products are strictly certified by SGS
and/or TUV - the world's leading inspection, testing, and
certification companies. Both SGS and TUV are Nationally Recognized Testing Laboratories (NRTLs) in North
America (approved by the Occupational Safety & Health
Administration [OSHA]) and Notified Bodies in the European Union.
Why SGS/TUV? The market
includes many certifying laboratories. From small-scale to
large-scale and non-reputable to reputable, every certifying
laboratory serves its own customer base. As part of our commitment
to providing superior-quality, safe, and reliable products, we
have selected SGS/TUV as our certifying partners. SGS and TUV conduct the most meticulous and thorough tests
required for safety certifications. Typical testing and certifying times
at SGS/TUV range from 3 to 6
months, compared to 3 days for some
other laboratories, such as SEM Test Compliance.
