RS232 DB9 FEMALE TO RS485/RS422
DB9 MALE OR TERMINAL BLOCK

The SerialComm CON-485/422-PI9 is an industrial grade bi-directional port powered RS232 to RS485 or RS422 converter in a 9 pin format. It can convert any standard full duplex RS232C port to any two-wire half duplex RS485 port or four-wire balanced full duplex RS485 or RS422 port. In simple terms, it will convert any RS232 signal to a RS485 or RS422 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 / RS422 driver when data is present on the RS232 side making the device plug-and-play, requiring no software drivers. The CON-485/422-PI9 has a DB9 female connector on the RS232 side and either a DB9 male connector or 5-way terminal block on the RS485 / RS422 side. Separate terminal block is included in package.

TROUBLESHOOTING INSTRUCTIONS

RS232 TO RS485 MODE OPTION:

Configure jumper settings to place two CON-485/422-PI9 converters in RS232 to RS485 mode. Perform a loop back test on a pair of CON-485/422-PI9 converters. Using figure 1, attach the two CON-485/422-PI9s to two serial ports on a PC and using two instances of a HyperTerminal program send a character from one and see if it echoes to the other. This will test both transmit and receive functions of the converter in RS485 mode.
RS232 TO RS422 MODE OPTION:

Configure jumper settings to place one CON-485/422-PI9 converter in RS232 to RS422 mode. Perform a loop back test on one CON-485/422-PI9 converter. Tie signals T+ to R+ and T- to R- of the CON-485/422-PI9. Attach the converter to the serial port on a PC and using HyperTerminal send a character from one and see if it echoes to the other. This will test both transmit and receive functions of the converter in RS422 mode.
