Turnkey Interface

Orders can be taken for the Turnkey MorseKOB Interface as detailed below.  Depending on demand and inventory at the time you order, it could take a few weeks to build, test, and ship a unit.  I am trying to keep a few completed units in stock so that I can get them out when orderd.  Please contact Chip Morgan with the details listed in the To order: section below.  Bare PCBs will be for sale if available, please contact me before ordering PCBs to check the availabiity - PCB pricing details below.

USB version:  Black plastic housing, 4.25" L x 2.6" W x 0.9" H; Integral USB adapter (FTDI drivers will be available on the MorseKOB website) with USB A to USB Mini B cable; removable plug-in connector with screw terminals for connection to the loop supply and telegraph equipment.  Unit will be fully assembled and tested.  $85, including shipping via USPS Priority Mail to addresses in the US.

RS-232 version:  Same as above, but USB adapter is replaced with a female DB-9 connector for use with a "real" serial port with RS-232 specs.  No cable.  $65, including shipping via USPS Priority Mail to addresses in the US.  Please make sure your computer has a real serial port before ordering this version.  Many computers, particularly laptops, have only USB ports.  If you don't have any DB-type connectors on your PC, you can be sure that you will need the USB version!

TVS Snubber:  One TVS diode will be included for use as a snubber across the sounder terminals. 
Two types are available:      a) for instruments of 100 Ohms or less
                                       b) for instruments greater than 100 Ohms
The diodes are selected assuming that the loop current running through the instrument is within the recommendations found on the MTC website for Electrical Specifications for Telegraph Instruments.  A photo of a non-destructive type of installation on a sounder can be seen at http://kob.sdf.org/morsekob/interface.htm#snubbers (solder it to the ring terminals to ensure a good connection).
Additional TVS Diodes can be ordered for $1 each with no charge for shipping if included with an interface order.

Extra Loop Connectors: $3.00 each with no charge for shipping if included with an interface order.

Bare PCB (no parts, no cable, no snubber diodes):  If available, bare PCBs are $12 each, including shipping via USPS Priority Mail to addresses in the US.

For shipping addresses in PA, 6% PA Sales Tax will be added to the order total.  For International orders, shipping will be via USPS Priority International Mail for an additional charge.
