All
above use very low power CMOS circuitry and, in most applications,
are powered entirely from the RS232 interface's RTS and/or DTR signals.
All can also be powered from an external DC supply, typically +9V.

Custom Design and Manufacture |
|
High
Volume Products
 We
offer a custom development service for all types of interface or
protocol converters, incorporating RS232, RS422, RS485, USB or fibre
interfaces. Illustrated are examples of some recent custom designs:
inline moulded converters that are extremely competitively priced
and delivered in 1000+ volume within 16 weeks from receiving customer's
specification. Most are based on the K2-ADE.
To achieve a very low price, parts of the manufacturing process
are carried out in the Far East using our own test equipment. Some
of the isolated converters use 10kV-rated BASEEFA optoisolators.
We
have also developed custom versions of our USB-485 converter, with
high voltage isolation suitable for reinforced isolation requirements
for 3 phase 415V AC supplies.
Custom
Protocol Converters
These
are usually based on the KD485-PROG
and occassionally on the PPC.
We have considerable expertise in the development of protocol converters
involving various protocols including MODBUS Master or Slave. The
software is developed to an agreed specification and can be tested
using customer's loan equipment. The customer normally receives
the full sources and subject to the purchase of the KD485 C COMPILER
/ MODBUS LIBRARY is able to maintain the program in-house.
Both
the KD485-PROG and the PPC have security features to prevent a user
application being transferred from one unit to another and this
enables value added resellers to resell our products with custom
software in them.
