Wiring information in this section applies only to single-reader applications. For 28SA-Plus’s used with the SK-SS Smart
Switch, use wiring information provided with that device or with the software.
The 11-65000 is designed to communicate with a printer, terminal, personal computer or a modem, using an RS-232
interface. The wiring for a printer cable is different from the wiring for a PC or Terminal. (see Figures 2 through 9 for
communications wiring instructions).
Cable distances of up to 300 feet (100 meters) are possible, using high-quality shielded cable, with the shield
connected to Earth ground at the reader end. Recommend 5-conductor, 18-24 AWG shielded cable, such as Belden
9535 (24 AWG), 9610 (24AWG), 9910 (24AWG), 9941 (22 AWG), or where Plenum rated cable is required, Belden 83506
Teflon insulated (24 AWG). Most cable manufacturers offer Belden equivalents. DO NOT USE un-shielded and/or
twisted pair wire, such as “Category 5” for RS-232 communications.
Route communications wiring away from equipment that generates RF interference, such as transmitters, fluorescent
light ballasts, large motors, compressors, elevators, etc.
Whenever communications cable runs enter or exit a building, lightning transient suppressors are strongly
recommended at both ends of those cables. Parking lot, pool gate, marina and tennis court applications with
long buried cable runs are susceptible to nearby lightning strikes, and unprotected Readers, PC’s, and Printers are
frequently damaged. Contact Secura Key for additional information on lightning suppression.
Wire runs of up to 4,000 feet are possible using “line drivers” (RS-232/422 converters). One converter is required at
each end of a two-twisted pair overall-shielded cable. Each converter will require AC power. If you have already
pulled wire for RS-232 and need to add RS422 converters, new twisted-pair cable must be pulled. Contact Secura
Key for the correct converter model for your specific application.
ModeM CoMMUnICAtIonS
The 11-65000 has been designed to communicate with a PC or terminal via modem in auto answer mode with any
Hayes compatible modem (minimum 1200 baud). The modem must be properly configured for operation with the
28SA-Plus. This is done by connecting the modem to the serial port of a PC, running a terminal program (supplied
with most modems), and by entering a setup string. Be sure that during modem setup, the terminal program is
communicating with the modem at the same Baud rate that the 28SA- Plus will be communicating. Note that some
modems also require DIP Switch settings. Also note that if using SA-LINKTM or SA-NET TM, you must install DOS modem
driver software in your PC, even if your PC is running Windows.
For example, to configure a US Robotics Sportster 14.4, 28.8, 33.6 or 56 kBaud modem, you would type in the following
string of characters (note that 0 = zero):
At&r1&d0&S0&H0S0=1&w0 [enter]
Then set DIP switches 1, 4, and 6 to ON and all others to OFF. Disconnect the modem and connect it to the reader.
Other modems may require a different setup string. Also refer to your modem manual. For further information,
contact Secura Key.
