Transio A52/53
Smart RS-232 to RS-422/485
Bi-directional Converter
Overview
Transio A52/53 is a smart RS-232 to RS-422/485
bi-directional converter, which allows one RS-232
port to be converted into an RS-422 or RS-485
port. With A52/53 you can control up to 32
devices, within 1.2 km, in a multidrop
environment.
Transio A52/53 is a Moxa Green Product. Moxa’s
Green Products satisfy the RoHS directive of the
European Parliament, and accordingly, do not
contain cadmium and cadmium compounds,
hexavalent chromium compounds, lead and lead
compounds, mercury and mercury compounds,
PBBs (polybrominated biphenyls), or PBDEs
(polybrominated diphenyl ethers).
To ease 2-wire RS-485 half-duplex control, fully
Automatic Data Direction Control (ADDC)
intelligence that requires no baud rate switch
settings is designed into each A52/53, simplifying
RS-485 software programming. Your applications
can easily manage data transmitting and receiving
via the half-duplex RS-485 port without using
additional code. Compared to other products that
require setting the clock speed manually with
switches, A52/53 lets you avoid many developing
and maintenance hassles.
To meet the high reliability required by harsh
industrial environments, all RS-422/485 signals
provide TVS protection, and ESD up to 25 KV. In
addition, A53 provides 2 KV of optical isolation
protection for all signals at the RS-422/485 end.

(DC) of optical isolation protection (A53
only)
• Provides overloading protection when there
are 2 signals shorted together at the

adapter can support up to 4 converters
• An external power adapter is required, with
input voltage for the converter ranging from
DC +9V to +30V.
• Operating temperature: 0 to 55°C
• Dimensions: 90 x 60 x 21 mm
• Mounting Kit: Plastic Plates and screws for
mounting A52/53 on the wall or any surface.
• Power consumption: A52: 157 mA max.
(+9V); A53: 285A max. (+9V)
Applications
• Multipoint data acquisition
• Factory automation
• Remote serial device control
• Building security automation
• Critical industrial control

Installation
Switch and jumper settings
To change the operation mode, remove the two
screws on top of the converter, open the cover,
and then use the array of sliding switches to set
the desired mode.
DIP switches are used to select the operation
mode (RS-422 or RS-485). For RS-485 mode,
the control mode (By RTS or ADDC) is also set
by DIP switch.

RS-422 mode Off
RS-485 mode On*
SW2

Auto Data Direction Control (ADDC) On*
(* Default settings)
In RS-422 mode, RxD is automatically set with
a 120 ohm terminating resistor.
In RS-485 mode, the 120 ohm terminating
resistor is set by one jumper.
When shorted, the resistor is enabled.
Basic Communication Wiring
Before placing a converter in an existing
network, the converter should be properly
configured. The following diagrams show
typical layouts for both converters.
LED Indicators
LED indicators for TxD, RxD, RTS, CTS
signals and PWR are located on top of
A52/A53. The indicator light is NOT lit when
there is no signal, or the power is off.
TxD: Shows green when connected and
transmitting data from RS-232 to
RS-422/485.
RxD: Shows green when connected and
receiving data from RS-232 to
RS-422/485.
RTS: Shows green when connected and
RS-232 RTS Signal is ON.
CTS: Shows green when connected and
RS-232 CTS Signal is ON.
PWR: Shows green when power is ON.
Power supply
A52/53 converters are designed for standard
+24 VDC unregulated power for use in
industrial environments. Operation is
guaranteed when using any power supply
between +9 and +30 VDC, 350 mA.
An optional power adapter (9V 1.5A UL/TUV
110V/230V) can support up to 4 converters
(see the following diagram).

Note: Each group of (DTR, DSR) pins are
shorted, freeing users from the hardware
flow control cable wiring problem. For
this reason, we list two types of RS-232
cable wiring below.
Type 1: To connect the RS-232 side of A52/A53 to
a DTE (e.g., PC COM1/2) or DCE (Be
sure to check the precise DTE/DCE
pinouts. The following DTE/DCE pinouts
are just an example)

COM1/2, with 3-pin wiring if you don't
need hardware flow control.
