A RS232 / Serial Loopback Tester designed to help test you either test your 9 Pin RS232 devices
or use for fault finding. Can work with a serial port terminal e.g. SimpleTerm Gold or PuTTY for easy testing.

A very handy, portable device as part of a serial port test tool kit.

We use these in house to test a range of our devices from USB to Serials and bespoke hardware RS232 designs
to make sure they go out working every time.

This RS232 serial loop back tester is a 9 Pin device and all connections are within the device.

If you need to extend this device, we would advise you to use a "straight through" cable
and not a "Null Modem".

Wiring:
The following wires are linked for loop back testing (including hanshaking signals)
i.e. 2 to 3 (TX,RX), 4 to 6 (DTR,DSR), 7 to 8 (RTS/CTS).

Has a female connection to allow you to connect to most serial devices.

If there is a similar product you need let us know and we may stock it for you depending on demand.
