QPS Fix Generator MK 2 - not sold anymore
General Description
The QPS Fix Generator MK 2 is a hardware extension manufactured by QPS to be used with the Qinsy software.
It has the possibility to receive and/or send closure (CLS) or TTL pulses.
Outgoing closure or TTL pulses can be used to activate external devices, whereas incoming closure or TTL pulses can be used for PPS (Pulse-Per-Second) support or fixmark activation from other navigation systems.
Device Description
The QPS Fix Generator supports 2 fix out ports (FIX OUT) and 1 fix in port (FIX IN). All ports can be configured to send (receive) closure or TTL pulses. The selection can be made with the switches on the front panel of the fix device. The switch in the up position (TTL) sets the particular port to TTL mode, down (CLS) sets it to closure mode. All fix ports are BNC connectors on the rear panel of the fix device. The length of the fix out pulses can be adjusted with the 2 pot meters next to the BNC connectors. The length of the pulses can be set between 0.1 second (100 milliseconds) and 2.2 seconds (2200 milliseconds). The time that the fix LED is on corresponds with the length of the pulse.
Make sure the core of the power supply wire has a positive polarity (12V).

Cable Diagrams
If Fix Out is used the fix device needs to be powered by a 12 Volts DC adapter (9 Volts will actually be enough).
The serial connection cable between the QPS fix device and the computer's COM port should be wired as follows:
DB-9M | Fix Device | DB-9F | COM port on pc | DB-25F | COM port on pc | |
|---|---|---|---|---|---|---|
Pin 3 | FIX out | — | Pin 3 | FIX out | Pin 2 | FIX out |
Pin 5 | SG | — | Pin 5 | SG | Pin 7 | SG |
If Fix In is used the connection between the fix device and the computer's COM port should be wired as follows:
DB-9M | Fix Device | DB-9F | COM port on pc | DB-25F | COM port on pc | |
|---|---|---|---|---|---|---|
Pin 2 | FIX in | — | Pin 2 | FIX in | Pin 3 | FIX in |
Pin 5 | SG | — | Pin 5 | SG | Pin 7 | SG |
Fix in and Fix out can be used simultaneously by using two cables and three connectors.
Connect pin 2, 3 and 5 of the DB9 connector cable from the rear panel of the QPS fix device to two different COM ports on the computer:
(The wiring of the two cables should be in accordance with the two diagrams given above.)
DB-9F OUT | COM port on pc | DB-25F OUT | COM port on pc | DB-9M | Fix | DB-9F IN | COM port on pc | DB-25F IN | COM port on pc | ||
|---|---|---|---|---|---|---|---|---|---|---|---|
Pin 2 | FIX in | — | Pin 2 | FIX in | Pin 3 | FIX in | |||||
Pin 3 | FIX out | Pin 2 | FIX out | — | Pin 3 | FIX out | |||||
Pin 5 | SG | Pin 7 | SG | — | Pin 5 | SG | — | Pin 5 | SG | Pin 7 | SG |
If Fix In is the only option used, for PPS support for instance, powering is still required but it can also be supplied through the DB9 connector on the rear panel, instead of from the external adapter.
If this last option is chosen the serial connection between the fix device and the computer's COM port should be wired as follows:
DB-9M | Fix Device | DB-9F | COM port on pc | DB-25F | COM port on pc | |
|---|---|---|---|---|---|---|
Pin 2 | FIX in | — | Pin 2 | FIX in | Pin 3 | FIX in |
Pin 4 | 5V in | — | Pin 4 | 5V out | Pin 20 | 5V out |
Pin 5 | SG | — | Pin 5 | SG | Pin 7 | SG |
If this wiring does not power up the QPS Fix Generator the external adapter will have to be used.
