Compatible with the Recommended Standards of RS232, RS422 and
RS485, UT-216 interface converter can convert the single-ended
RS232 signal into balance differenced RS422 or RS485 signal. Also,
there is a rapid transient voltage suppression protector for
protection of RS422 RS485 interface with advanced TVS (TRANSIENT
VOLTAGE SUPPRESSOR) technology adopted.
Under normal conditions, the TVS tube is in the state of high
resistance. However, when both ends of the TVS tube are hit by a
transient high energy, the impedance at both ends can be depressed
by the TVS at a very high speed, and after absorbing a high
current, the voltage between the two ends is suppressed and kept at
a pre-set value, therefore no damage is caused to the electrical
components behind by the transient high voltage impact.
The protector can effectively restrain lightning or ESD (electro
static discharge) with a protection voltage of 600W on each line
for lightning surge and surge voltage or transient over voltage
possibly caused up by various reasons, and at the same time, a
high-speed transmission of RS422 RS485 interface is ensured by the
tiny capacitance between the poles. Through a DB9 female connector
RS232 interface is connected to other interfaces compatible with
RS232 standard, and for RS422 and RS485 interfaces a DB9 male and
RJ45 connector is to be used for connection. The unique I/O circuit
of the internal zero delay auto transceiver contained in the
converter controls the data stream direction automatically without
any handshaking signal (for example RTS, DTR etc). The converter is
plug-and-play without any jumper settings needed for mode shift
between full duplex (RS422) and half duplex (RS485).
The converter is applicable for all the existing communication
software and interface hardware without any software modifications
for the previous working mechanism based on
A reliable and stable point-to-point and
point-to-multipoint communication can be ensured by UT-216
photoelectric isolation interface converter. For
point-to-multipoint communication, as many as 32 interface
facilities of RS422 or RS485 standard can be connected to each
converter, and a high data transmission rate of 300-115.2Kbps can
be achieved. Power indicator light and data traffic indicator light
are also available with the converter for malfunction indication.
Two conversion communication modes including RS232 to RS422 and
RS232 to RS485 are supported.
