25 Pin RS232 to RS485 Converter

Serialcomm - Model CON-485-PE25

   Commercial vs Industrial ?
There are no quality differences between the two.  All of our converters come with a 5 year warranty and are made to last. The only difference is the operating temperature range. Industrial typically is from -40°F to 185°F as compared to Commercial which typically is from -5°F to 140°F.   For most applications, industrial converters are not necessary and especially for indoor usage, commercial converters provides the best value.

The SerialComm CON-495-PE25 is a high quality economical bi-directional port powered RS232 to RS485 converter in a 25 pin format. It can convert any standard full duplex RS232C port to any two-wire balanced half duplex RS485 port. In simple terms, it will convert any RS232 signal to a RS485 signal and vice versa. The unit is powered from the RS232 data lines. It also supports data direction auto-turnaround. Therefore, no external power or flow control is required. The data direction auto-turnaround automatically enables the RS485 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers. The CON-485-PE25 has a DB9 female connector on the RS232 side and a DB9 male connector on the RS485 side.

TROUBLESHOOTING INSTRUCTIONS

 

Perform a loop back test on two CON-485-PE25 converters. Attach the two CON-485-PE25s to two serial ports on a PC and using two instances of HyperTerminal, send a character from one and see if it echoes to the other. This will test both transmit and receive functions..
