RS232 to RS422/RS485 programmable converters

Programmable converters which can manipulate the data stream, using a user-developed program.
The PPC Programmable Protocol Converter has four serial ports which are RS232 but can be field-changed to RS422/485. It is programmed in Pascal (built-in) or C (a compiler purchased separately).
The KD485-PROG has two serial ports which are factory configured with any combination of RS232, RS422/485, or 20mA loop (TTY). It is programmed in C, with a compiler purchased separately.

KK Systems also offer a custom programming service.
