Adapter Panel Bluetooth Modification



Paramount ME Adaptor Panel +5V Power Modification

Paramount ME Adaptor Panel modification  - WARNING! This modification should be preformed by a qualified electronics engineer or technician!

Background

By performing this modification, you have a very clean and convenient solution to powering a Bluetooth or Wi-Fi adaptor.

NOTE: Software Bisque has redesigned the Adaptor Panel to power third-party devices (Wi-Fi and Bluetooth) as well as perform hardware handshaking required by some Bluetooth devices. The new adaptor panel can supply the +5 volts directly to pin 9 of the serial port and a tie pins 7 and 8 where needed using 2 DIP switches. The Adaptor Panel Revision F can be purchased from the Software Bisque Store.  If you are leery about performing the modification purchasing a newer updated model is the better option. Please refer to the latest Paramount ME manual for details.

adaptor Panel Removal: Preparing for the Modification

To remove the Adaptor Panel you will need a 5/32-inch hex key. One is supplied with the Paramount ME. Start by removing the 14 - 10/32 NF by 3/4th socket cap screws that hold the adaptor panel in place.

You will also have to remove the wires from the backside of the adaptor panel before it will become free. The purple power cable, the ribbon cable, and the DIN power cable. Note the location of each before removing them. All but one of the connectors are notched (idiot proofed). This is connector labeled J3 where the purple power cable is connected.

The purple wire that supplies power to the adaptor panel must be oriented such that the notched side of the white connector faces TOWARDS the large black heat sink.  See below showing exactly this. Plugging any power connector in backwards is asking for trouble!

Purple Power cable

Be careful!

Other connectors are notched or keyed

Note keys on the other connectors!

Again, be careful when reconnecting the cables. With a bit of force you can still plug a notched cable in backwards!

WARNING!

If you are inexperienced at soldering it is best to have someone else perform the modification for you! Or contact Software Bisque directly for options. You must be very careful soldering the wire in place and you must avoid the possibility of the wire shorting out by touching the other pins on either side. See the disclaimer below.

HINT: A bit of Hot Glue will keep the wires in place and keep them from being shorted. Place glue around all the connectors used in the modification.

Location of PC to Serial DB-9 connector on the adaptor Panel

The female serial port connector is the one located closest to the large black heat sink. The location is indicated below. Also note the pins being used in the modification are highlighted. The advantage to this easy to perform mod is you don't have to remove the adaptor panel from the housing and there is nothing to get in the way of soldering the +5 volt line to Pin 9. As long as you are careful to short across adjacent contacts you will be fine.

The pin to use is square not round by the way!

If your Bluetooth adaptor doesn't require hardware handshaking don't bother tying pin 7 to pin 8! Even easier!

 Pin 9 highlighted and 7 tied to 8 (may not be needed)

Very nice and easy to do!
Don't tie 7 to 8 unless the device needs it

Hardware handshaking CTS pin 7 and RTS pin 8 tied

NOTE: Tying pins 7 and 8 is not required with all Bluetooth serial adaptors! The Parani10, Air Cable, and Free2Move devices do not for example. These devices can disable handshaking. However, remember some of these require the additional null modem adaptor and/or male to male gender changer which is not as clean.

Consider hardwiring (or jumping) pin 7 to pin 8 of the Adaptor Panel's 9 pin female serial port. This satisfies the hardware handshaking needed by the Socket Serial adaptor and will not cause a problem if another brand is used. See the back of the adaptor panel centered on the serial connector below.

Tie 7 and 8 together - Pin 9 is 5 volts power
Not required with ALL Bluetooth serial devices

Hot Glue to protect your work

By placing hot glue over the pins you can protect them from pulling loose or being shorted.

Protect wires!

Final Touches

Place another dab on the middle of the 5 volt affixing it to the adaptor panel.

 

Now the Bluetooth serial adaptor is powered by the Paramount ME! Using the Socket brand or Air Cable Bluetooth serial adaptor all that is required is the serial adaptor plugged directly into the Paramount ME's female 9 pin serial port. No additional adaptors (gender changer/null modem) or external wiring for power is required. Very clean and slick because the Bluetooth serial adaptor is powered by the Paramount ME!

WARNING! Use of a serial cable with all 9 wires connected AFTER performing the modification is not recommended. The serial cables supplied with the Paramount ME have all 9 wires connected do not use the supplied cable.

When the adaptor panel modification has been performed you should NO LONGER use a straight through 9 pin male to 9 pin female serial cable with the Paramount ME. This includes the default 25 foot length serial cable supplied with the Paramount ME uses all 9 lines.

In doing so you would be supplying +5 volts directly to pin 9 - Ring Indicator on the PC or Laptop computers' serial port. I do not know what that could or would do! Just eliminate the use of pin 9 in the serial  cable and there is no problem. All that is needed for serial communications with the Paramount ME are pins 2, 3, and 5 ground, wired straight to each other.

Option Two for supplying +5 volts power using Aux power Connector #2

Using the same + 5 volt pin for power described above wire from there to the center post of the Aux 1 or Aux 2 power connector. Aux 2 is shown here. To the left in the image below is Aux 1. Either will work!

Alternative source for power

NOTE: If you choose this method DON'T forget that you now have an active power connector! Do not plug anything in this Aux connector that requires more than +5 volts center pin and minimal power requirements, i.e. the low power consumption Bluetooth serial adaptors. Probably best to place a label on the connector used so you don't forget or use Pin 9 for power instead!

If you Bluetooth adaptor requires hardware handshaking also make sure you tie pin 7 to pin 8, i.e. Socket brand Cordless Serial adaptor.

Option Two - Finished but not as neat!

Clicking Sound when Connecting/Disconnecting - Paramount ME

The small clicking sound you here connecting to the Paramount ME is normal. You will hear the click once when establishing the connection and once when disconnecting. You may also notice a single packet error when first establishing the connection. This too is normal.

Disclaimer

Note that only qualified persons should perform this modification. Improper soldering could cause damage to the board voiding the warranty on the Adaptor Panel!
