Patton electronic 1185, 1184 Installing the New QuickConnect Module, Connection to a DTE Device

Installing the New QuickConnect™ Module

1)Make sure the power switch is off. Leave the power cord plugged into a grounded outlet to keep the unit grounded.

2)Hold the module with the faceplate toward you and align the module with the guide slots in the rear panel of the Model 1184/1185.

3)While keeping the module’s faceplate parallel with the Model 1184/1185 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.

4.2.2Connection to a “DTE” Device

The serial port on most QuickConnect™ interface modules (all except the X.21 module) are hard-wired as 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 D as a guide.

4.2.3 Connection to a “DCE” Device

The serial port on most QuickConnect™ interface modules is hard- wired as a DCE (all except the X.21 module). Therefore 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 D 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 Technical Support at

4.2.4 Re-configuring the X.21 QuickConnect™ Module

The serial port on the X.21 QuickConnect™ 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 POWER CONNECTION

The Model 1184/1185 is available with three power supply options:

Standard AC Power Supply option (Model 1184/1185, or 1184/1185-230) is switchable between 100 and 253 VAC and is available with a variety of domestic and international power cords. (See Appendix C).

Universal Interface AC Power Supply option (Model 1184/1185- UI) operates in environments ranging from 85 to 256 VAC, with no re- configuration necessary (see Appendix C for available domestic and international power cords).

DC Power Supply option (Model 1184/1185-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 two AC power supply options–Standard and Universal–are 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 1184 or 1185.

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

3)Turn the rear power switch ON.
