Serial data analyser adds conversion
functions
Handheld serial data analyser can now act as a level convertor, and as a half to full-duplex or full to half-duplex convertor.
New Forest Electronics has added an "online download" feature to its handheld serial data analyser This allows it to continuously retransmit serial data as they are received

New Forest Electronics reckons its SDA-02 handheld serial data analyser is the first instrument of its type to incorporate a time-stamping function.
Serial data analyser becomes transmitter
New Forest Electronics has added a significant new feature to its SDA-02 handheld serial data analyser.
As the analyser can accept serial data at CMOS/TTL and RS485/422 signal levels, and retransmit at RS232 signal levels, it can therefore now provide several conversion functions.
Online download allows the analyser to be used as a "front end" to feed a second equipment or PC.
In particular it can be used as a level convertor.
For instance the analyser can connect RS485/422 or CMOS/TTL signals to a PC equipped with only RS232 input COM ports.
It can also act as a full to half-duplex convertor to combine two separate data lines (eg RS232 transmit and receive signals) onto one data line, in such a way that the data bytes are always separated even when arriving simultaneously.
This allows a PC running an application with only a single serial data input (eg Microsoft HyperTerminal) to monitor data on two signal lines.
It can also act as a half to full-duplex convertor - ie to divide half-duplex data onto two physically separate lines.
This allows a user running a PC application with two serial inputs to clearly visually separate for instance half-duplex signals monitored on an RS485 two-wire line.
