The Delta Series models include the Delta3, Delta5, and Delta 6.4. The Delta 6.4 is simply a Delta5 with a
keypad attachment.
All Delta Series Readers are compliant with the following organizations:
FCC compliance Statement: This device complies with part 15 of the FCC rules. Operation is subject to the
following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause undesired operation. Changes made to this
equipment that is not authorized by Farpointe Data Inc. may void the user’s authority to operate the equipment.
1.0 Cable Requirements
All readers operate at up to 500 feet (152 m) of cable, using nine-conductor, shielded, stranded cable. Per the
Security Industry Association’s Wiegand specification, AWG 24 (such as Belden 9539) is the minimum gauge
required for data transfer in a 500-foot run length. However, the proper wire gauge to use must be determined by
the current draw requirements of the reader, the length of the cable run, and the voltage applied to the reader.
If the reader is to be operated at 5 VDC, 5 VDC must be available at the reader (long cable runs have a voltage
drop due to the resistance in the cable). A larger gauge of wire (having less resistance) or a separate power
supply near the reader may be required to ensure 5 VDC is available at the reader.
2.0 Reader Modes
Delta Series readers can be configured to operate in any of the following modes:
• Sector Only Mode: Reader looks for access control data in a secure sector but if no valid data is found
the reader outputs nothing. This is the default mode.
• CSN Only Mode: Reader does not look for access control data in a secure sector data and simply
outputs the card’s CSN.
• Sector Plus CSN Mode: reader looks for access control data in a secure sector but if none is found the
reader outputs the card’s CSN instead.
3.0 CSN Output Formats
Delta Series readers can be configured to output the card’s CSN in any of the following ways:
• 32-bit Wiegand: The reader outputs the 32-bit CSN as Wiegand data starting with the MSB. This is
the default mode.
• 26-bit Wiegand: The reader outputs 26-bit Wiegand data comprised of the 16 lower bits of the 32-bit
CSN, fixed 8-bit facility code, and beginning and ending parity bits. Facility code defaults to 001
(Note: cutting off 16 MSBs from CSN can cause card duplication).
• 34-bit Wiegand: The reader outputs 34-bit Wiegand data comprised of the 32-bit CSN MSB first plus
beginning and ending parity bits.
• 40-bit Wiegand: The reader outputs 40-bit Wiegand data comprised of the 32-bit CSN followed by an
8-bit check sum.
• Magnetic Stripe (ABA Track II, clock and data, with card present): 32-bit CSN is output in ABA Track
II format.
4.0 Secure Sector Access Control Data Output Formats
Access control data programmed onto a secure mifare sector can be output in any of the following ways:
• Wiegand (industry standard 26-bit Wiegand and custom formats)
• Magnetic Stripe (ABA Track II, clock and data, with card present)
5.0 Grounding
Shield (drain) continuity must run from the reader to the access panel. Shield (drain) and reader ground must be
tied together at the access panel and connect to an earth ground at one point.
