Models 4WSD9TB and 4WSD9R, universal serial converters, provide RS-232
to RS-422/RS-485 conversion using either port-power or an external power
supply. Model 4WSD9TB has a terminal block RS-485 connector; Model
4WSD9R has a DB9 female RS-485 connector.

Data is converted in both directions, RS-232 Transmit Data is converted to
balanced RS-422 or RS-485 Transmit Data. Received RS-422/485 signals are
converted to RS-232. Unlike converters which require programming hardware
handshaking signals to control RS-422 or RS-485 operation, Models 4WSD9TB
and 4WSD9R provide automatic Send Data Control. In RS-485 mode, the
RS-485 driver is enabled by circuitry which senses the RS-232 TD input. In
half-duplex RS-485 mode, the receiver is enabled when not transmitting. For
full-duplex operation, the receiver is set always enabled.

In RS-422 mode, the transmitter and receiver are always enabled. The
operating mode is set with 4 switches see Table 1. The converters are
powered by the RS-232 signal lines whether they are set high or low. If not
enough power is available from the port, or no handshaking lines are available,
a DC jack is provided to connect an external 12VDC supply. The DB9 female
connector for RS-232 is wired as DCE (like a modem).
The RS-232 port has a female DB9 connector with pins 2 (RD), 3 (TD), and 5
(Signal Ground) supported. Pins 7 (RTS) and 8 (CTS) are tied together, and pins
6 (DSR), 1 (DCD), and 4 (DTR) are also tied together. Any incoming data lines
in either the high or low state are used to port power the converter. The more
handshake lines available, the more likely the unit can be port powered. Table 2.
shows the RS-232 pinout.

No external power is required if two RS-232 output handshake lines are
available and the cable run is short. If the handshake lines are raised and no
termination is used, the power efficiency is greatly increased. Less than 3 mA
is required to operate the converter - plus the load current. For applications
that do not have handshake lines or require a large load current, power may
be externally supplied with a +12 VDC power supply with a 2.5mm plug (tip
positive).
Although handshake lines can be used to power the converter, no handshaking
is required to control the RS-422/RS-485 driver. With Switch 1 set to RS-422, the
driver is always enabled. When Switch 1 is in the RS-485 position, the RS-485
driver is automatically enabled during each spacing state on the RS-232 side.
During the marking or idle state, the RS-485 driver is disabled and the data lines
are held in the marking state by the 4.7K Ohm pull-up and pull-down resistors.
The value of these resistors may need to be changed to a different value when
termination is used in order to maintain the proper DC bias during the idle state.
All product specifications are subject to change without notice.
