Description:

Electronic interface: At the side of RS-232 is a DB9 female (hole-type) connector. At the side of RS-485 is a DB9 male (needle-type) connector, with connection board.

Uses with this item Adding an RS-485 interface to a PC via RS-232 is now a snap.

This interface converter does this without requiring any AC or DC power.

Features a female DB9 connector(EIA/TIA), thus allowing it to be plugged directly into any one of the PC's Com ports.

It uses a particular pump to gain power from RS-232 signal (RTS, DTR, TXD) without initializing the RS-232 series interface.

 Specifications :

• Data Transfer Rate: 300-115200bps
• Operating Distance: 1200m for RS485, 5m for RS232
• Power: None required, uses TD as power source
• Environment: -10C to 85C, 5% to 95% RH
• Interface: Compatible with EIA/TIA RS-232C standard and RS-485 standard.
• Working mode: Asynchronous, half-duplex, differential transmission.
• Transmission media: Twisted-pair or shielded twisted pair (STP).
