RS-232 to RS-485 Connector (CONV485)

Product Description

RS232 and RS485 bidirectional switch.
Passive pocket-sized design is suitable to the many kinds of environment. The ultra low power loss, under three striations condition work normally Does not have retards, fast retransmits. -20~70º C width warm operating temperature.

CONV485 is one section general level low cost RS-232/RS-485 switch, uses the pocket-sized contour design, matches has may insert pulls out, the installment is simple, dexterous. It can from RS-232 connection TXD, RTS and the DTR signal gain power source, even if in only has when the TXD signal power supply also can normally work. Widely uses in the control, sells system and so on in food and parking lot.

2. Characteristic:
* The volume is exquisite, the installment is simple
* The unique string mouth takes the electricity technology, guarantees string mouth when three work, still could normally work
* The power loss is extremely low, when static work equates to the ordinary light emitting diode power loss, mays be called true " passive "
* Uses the data flows to the automatic control technology, automatic distinction and control data transmission direction
* Automatically detects the string mouth signal speed

3. Communication target:
Standard: Conforms to EIA RS-232, the RS-485 standard
RS-232 signal: TX, RX, GND
RS-485 signal: D+, D-, GND

Work way: Asynchronous work point-to-point or multi- spots, 2 half-duplexes
The direction controls: Uses the data flows to the automatic control technology automatic distinction and control data transmission direction
Baud rate: 300-115200bps, automatically detects the string mouth signal speed
Load capacity: Supports 32 wheels inquires the environment (may have custom-made 128)
Transmitting range: RS-485 carries 1200 meters (when 115200bps), the RS-232 end suggests does not surpass 5 meters
The connection protects: The 600W surge protects the 15KV static electricity protects
Connection form: RS-232 carries the dB-9 mother head, RS-485 carries dB-9 male or 3

4. Environment target:
Operating temperature: -20 to 70
Memory temperature: -40 to 85

5. Power source target:
Inputs the power source: Needs not the external power supply from RS-232 mouth TXD, RTS, DTR signal gain power source
Power loss: Within static power loss 10mA, within dynamic power loss mean value 40mA

6. Outward appearance target:
The long * width * is high: 90mm: 33mm: 16.5mm
Outer covering: Models the shell
