9 and 15 Pin Y Connectors

[Bob Garrett]

Greetings Listers,

 

I'm getting ready to configure my K3 with my THP amplifier, Microham
DigiKeyer II and my K3 Pod with is a speech box for us blind hams.  I know
connecting more than one device to a 9 and/or 15 pin port is a slippery
slope however, I need to do it and will figure out the conflicts along the
way.  

 

Does anyone have a source for good quality 9 and 15 pin Y connectors?
Please let me know and thanks in advance for your help.  73, Bob K3UL

Bob – I get most of my cables and splitters from www.cablewholesale.com.  Here’s a link to a DB9 splitter:

And here’s a link to a DB15HD splitter:

www.cablewholesale.com/specs/vga-splitter-cable/10h1-27708.htm

These splitters have all pins connected through.

Note: you can not use a full DB9 splitter with microHAM interface
and the K3.  You must use a "listen only" Y - one that connects
the "foreign" device to only the data *from* the K3.  The data
lines *to* the K3 can connect only to the microHAM interface (or
computer).

Bob,

I don't have a source, but I need to give you some information regarding
the 9 pin connector.

The 9 pin 'Y' may give you problems.  RS-232 signalling is for point to
point communications only.  If there are two drivers on a signal line,
they will interfere with each other (even if idle).
In other words, if there is anything connected to pins 3, 4 or 7 in the
device on the far side of the "Y" connector, it will interfere with
communications between the K3 and the computer (Microham Digikeyer).

In other words, you cannot connect another device that normally drives
an RS-232 interface.
Anything that is connected to the "Y" must be 'listen only'

73,
