HXSP-158RS232 serial port photoelectric isolator, also known as serial port isolator
(ISOLATORS), It uses advanced photoelectric isolation technology, which greatly
It protects the RS-232 serial interface equipment, avoids the ground line voltage, surge,
Harmful damage to RS-232 equipment caused by lightning strikes, static electricity, hot plugging, etc.
2. Performance parameters
①, interface: in line with EIA RS-232 and CCITT V.24 asynchronous protocol;
② Connector: DB9 connectors are used on both sides;
③ Transmission mode: asynchronous, full duplex, full transparency
④ Isolation voltage, 2500V continuous or 7500V pulse;
⑤ Communication rate: 0-57600BPS;
? Power supply: power supply from RS-232 interface(TXD, RTS or DTR);
?、Working environment: 0℃ to 50(0%-95%RH);
Three, connectors and signals
Comply with EIA RS-232 CCITT V.24 standard. 2, 3 pins are numbers
According to transmission and reception; 7 and 8 pins are RTS and CTS. 4,1 pins are DTR and
DCD; 6 pin is DSR; 5 pin is GND
RS-232 interface(TO DTE) RS-232 interface(TO DCE)
Connector: Use DB-25/9 hole type connector Connector: Use DB-25/9 hole type connector
Signal: internal signal lines are independent signal: internal signals are independent
1. Model selection
Users should first understand how many signals their RS-232 system uses
Cable, and then choose the suitable model to protect your RS-232 communication system.
2. Connection method
HXSP-158 can be serially connected to the original RS-232 series connection RS-232 interface
Between the ports, at either end, pay attention to the TO DTE direction. Generally speaking, PC
Multi-user belongs to DIE equipment, MC multi-user belongs to DCE equipment, but not necessarily
To truly judge that the device is DIE, the signal line of the RS-232 interface of the device should be
Get started. 2 pin sends and outputs DIE, 2 pin receives input
