485SD9R shown
These port-powered, two channel converters allow your computer to
communicate longer distances by converting TD and RD RS-232 lines to
RS-485 signals. RS-485 also provides multi-drop capability.

All converters feature Automatic Send Data Control which enables the
driver when data is present on the RS-232 side. Control of the driver is
automatic at speeds up to 115.2 kbps.
✔
The unit is powered from the RS-232 data and handshake lines whether
the lines are high or low. No handshake line change is necessary to
control the data lines. The RS-485 driver is enabled with each bit of
data. The RS-485 receiver is disabled when the driver is enabled and is
enabled when the driver is disabled. Model 485SD9TB can be optionally
powered by an external 12 VDC power supply.
ACCESSORIES
SM16-12-V-ST - Power Supply, 12 VDC 6 Watt, Stripped and Tinned, International
AC Input, International AC Blades
9PAMF6 - DB9 male to DB9 female adapter cable, 6 ft. (1.8 m)
These converters are suitable for field service, where a power supply
would add clutter, or anywhere you need compact, easy-to-use,
economically priced serial conversion.
Why use an “optional” power supply
with a port-powered converter?
Automatic Send Data Control Explained
As operating systems become more complex, it is increasingly difficult to control
an RS-485 driver with standard software and the RTS line. This is especially true
in Windows and multi-tasking operating systems. With Advantech B+B SmartWorx’
Automatic Send Data Control circuit, driver control is in the converter hardware, so
you do not have to work with software at all.
Simply put, all RS-232 ports are not created equal. Many laptop PC’s, for
example, deliberately reduce power to the RS-232 port to save the battery.
And, if you are working at the distance limits of RS-422 or 485, you might need
an extra boost. For the majority of applications though, the converter’s port
powering is sufficient to accomplish the task.
The circuit monitors data flow and enables the driver during transmission and
automatically disables it when no data is being sent. There is no need to rework
software or install new drivers. Most Advantech B+B SmartWorx RS-232 to RS-
485 converters and RS-485 serial cards include Automatic Send Data Control.
