Model 422CFCR
www.advantech-bb.com
PRODUCT FEATURES
• Converts 4 channels unbalanced RS-232 signals to balanced
RS-422 signals
• Data rates up to 115.2 kbps
• Extends RS-232 line up to 1200 meters (4000 feet)
• RS-422 driver can drive ten RS-422 receivers in parallel
• Ten receivers can be connected to any one driver for use in
multidrop systems
Model 422CFCR, 4-channel RS-232 to RS-422 converter, converts unbalanced
RS-232 signals to balanced RS-422 signals. Model 422CFCR supports TD, RD,
RTS and CTS. The RS-422 Standard uses a balanced voltage digital interface
to allow communications of 90k bits per second on cable lengths of 1200
meters (4000 feet). Ten receivers can be connected to any one driver for use in
multi-drop systems.

The polarity of the two RS-422 lines must be correct. With no data being sent,
the RS-232 line should be negative and the RS-422 “A” terminal should be
negative with respect to the “B” terminal. If your equipment uses a “+” and “-”
naming scheme, in most cases, the “A” line will be connected to the “-”, and the
“B” line will be connected to the “+”.
The RS-422 Standard wire recommended is number 24 AWG copper
conductor, twisted-pair telephone cable with a shunt capacitance of 16 pF per
foot. For long runs and/or high rates (more than 200k bits per second), it is
recommended that the wires be terminated with a resistor at the receive end.
The twisted pair usually used has an impedance of about 100 Ohms, therefore
a 100 Ohm resistor is normally used for the termination. In no case should the
resistive termination be less than 90 Ohms.

REGULATORY APPROVALS
The RS-422 driver has the ability to drive ten RS-422 receivers, connected in
parallel. A system of multiple receivers may require some experimentation with
location and size of termination resistors, line lengths, grounding, etc.

The RS-422 Standard recommends that Protective Ground (pin 1) be
connected to a good “green wire” ground. This may already be connected
in your RS-232 equipment. Protective Ground and Signal Ground should be
connected through to each end of the system and be connected to each other
using a 100 Ohm 1/2 Watt resistor at one end only. If a shielded, twisted pair is
used, the shield should be connected to Protective Ground.
