2)Hold the module with the faceplate toward you and align the module with the guide slots in the rear panel of the Model 1092A.

3)While keeping the module’s faceplate parallel with the Model 1092A rear panel, slide the module straight in – so that the card edge contacts line up with the socket inside the chassis.

NOTE: The card edge connector should meet the socket when it is almost all the way into the chassis. If you encounter a lot of resistance, remove the module and repeat steps 2 & 3.

4)With the card edge contacts aligned with the socket, firmly seat the module by using your thumbs to apply pressure directly to the right and left edges of the module faceplate. Applying moderate and even pressure should be sufficient to seat the module. You should hear it “click” into place.

5)To secure the module in place, push the thumbscrews into the chassis and turn the screws clockwise to tighten.

4.2.2Connecting to a “DTE” Device

The serial port on most QuikConnect™ interface modules (all except the X.21 module) is hard-wired as a DCE. Therefore these modules “want” to plug into a DTE such as a terminal, PC or host. When making the connection to your DTE device, use a straight through cable of the shortest possible length—we recommend 6 feet or less. When purchasing or constructing an interface cable, please refer to the pin diagrams in Appendix C as a guide.

4.2.3 Connecting to a “DCE” Device

If the Model 1092A’s QuikConnect™ interface module is hard- wired as a DCE (all except the X.21 module), you must use a null modem cable when connecting to a modem, multiplexer or other DCE device. This cable should be of the shortest possible length—we recommend 6 feet or less. When purchasing or constructing a null modem interface cable, use the pin diagrams in Appendix C as a guide.

NOTE: Pin-out requirements for null modem applications vary widely between manufacturers. If you have any questions about a specific application, contact Patton Electronics Technical Support.

4.2.4 Configuring the X.21 QuikConnect™	Module
The serial port on the X.21 QuikConnect™	Module is default wired

as a DCE, but may be switched to a DTE. This is done by reversing the orientation of the DCE/DTE strap, as described below:

To reverse DCE/DTE orientation, remove the module according to the instructions in Section 4.2.1. The DCE/DTE strap is located on the bottom side of the module’s PC board. The arrows on the top of the strap indicate the configuration of the X.21 port (for example, if the DCE arrows are pointing toward the DB-15 connector, the X.21 port is wired as a DCE). Reverse the DCE/DTE orientation by pulling the strap out of its socket, rotating it 180º, then plugging the strap back into the socket. You will see that the DCE/DTE arrows now point in the opposite directions, showing the new configuration of the X.21 port. Reinstall the module according to the instructions in Section 4.2.1.

4.3 CONNECTING POWER

The Model 1092A is available with two power supply options:

Universal Interface AC Power Supply option (Model 1092A-UI) operates in environments ranging from 100 to 253 VAC, with no re- configuration necessary (see Appendix B for available domestic and international power cords).

DC Power Supply option (Model 1092A-DC) operates in 48 VDC environments and is equipped with a 3-pin “terminal strip” style connector.

4.3.1 Connecting to an AC Power Source

The Universal Interface AC Supply is equipped with a male IEC-320 power connection. A domestic (US) power supply cord is supplied with the unit at no extra charge. To connect the standard or universal power supply, follow these steps:

1)Attach the power cord (supplied) to the shrouded male IEC-320 connector on the rear of the Model 1092A.

2)Plug the power cord into a nearby AC power outlet.

3)Turn the rear power switch ON.
