About

Proximity

This utility helps determine the correct number and facility code for access cards or fobs. It converts binary or hexadecimal card values into usable data, and can also reverse the process by generating binary values from facility codes and card numbers.

Highlights
  • Binary to number conversion
  • Hexadecimal to number conversion
  • Number to binary generation
  • Supports multiple bit lengths
  • Supports numerous card formats
  • Reverse calculation functionality

Have a "naked" access card or fob and need to determine its appropriate number and facility code? If you're able to extract the binary or hexadecimal value then Proximity will do the rest. The first calculator of Proximity works one of two ways: By inputting the raw binary value of the card or by inputting the hex equivalent. To use the binary input, simply tap on the box and type in the binary value. The counter in the lower-right corner of the box will keep track of the amount of digits currently displayed. To use the hex input, tap on the box and enter the hex value. Once complete, select the bit length from the wheel below. This is only necessary when calculating from a hex value. After tapping on calculate, the output will be displayed. If there is more than one system in the same bit length, tap on Next to cycle through the different formats. The second calculator is simply the reverse of the first: 
Input the facility code, card number, select the format, and tap calculate to generate the raw binary value. More formats will be released in future versions so long as the information is acquired. If there's a format not on this app and you have the breakdown information, send it to me and I'll fulfill the request. Currently supports the following formats: 26 bits HID® Standard (H10301) 26 bits Indala 31 bits HID® ADT 33 bits HID® Standard (D10202) 34 bits HID® Standard (H10306) 34 bits HID® Northern (N1002) 34 bits Indala Optus 35 bits HID® Corporate 1000® 36 bits Simplex 36 bits Lenel 36 bits S2 37 bits HID® Farpointe (H10304) 37 bits HID® (no Facility Code) (H10302) 37 bits HID® PointGuard 37 bits Software House 40 bits Casi Rusco 40 bits XceedID 40 bits Honeywell (P10001) 48 bits HID® Corporate 1000® Disclaimer:

Read full description

The Z-COMM SSG series of Smart Phase Locked Loop (PLL) modules provide high performance in a compact package suitable for any number of applications. Fully programmable through a unique Bluetooth interface, or USB cable, the user may adjust functions such as frequency, sweep mode, step time, step size, and power output, among others. LED indicators provide a visual cue of the status of the various functions. Its rugged enclosure lends itself to in-field use as well as bench top testing. The highly reliable output signal, excellent phase noise, and flexibility of an internal reference or input for an external reference, provides RF engineers with an adaptable RF tool.
