HandKey II Installation and Operation Manual
Revision 2.0 Page 19
The master/remote network requires user enrollment at the “master” Hand Reader. The
master Hand Reader distributes hand template data with ID numbers and time
restrictions (if any) to the other Hand Readers in the network. Users removed at the
master Hand Reader are automatically removed from the remote readers. A printer
connected to the master Hand Reader will report transactions from all Hand Readers
on the network.
The master/remote network is highly effective with systems using card reader
emulation mode for user populations smaller than 500 people since it does not require
a host computer to manage the Hand Reader template database. Recognition Systems
highly recommends using Backhand™ software to backup template information
stored in the Hand Reader.
Remote Hand Reader in a Hand Reader Network Connected to a Host PC
Multiple Hand Readers can be linked to a personal computer (PC) for an integrated
access control network. Real time monitoring of door status and a variety of alarm
types can be done with Recognition Systems’ HandNet for Windows™ (Recognition
Systems model number HN-300) software. To run HandNet for Windows™ the
computer must be PC compatible, using a Pentium™-166 or faster microprocessor and
it must have a CD-ROM.
• The HandNet software can monitor over 1,000 Hand Readers simultaneously.
• An unlimited number of sites can be created with up to 32 Hand Readers per site.
• The Hand Readers report all transactions to the PC. The HandNet software records
all transactions and displays a variety of reports generated from this information.
• Template management is handled automatically.
• Users may enroll at any Hand Reader in the system. The PC collects the data and
distributes it to other Hand Readers in the network.
• Access may be restricted by time and by Hand Reader via HandNet’s access
profiles and by the use of time zones.
Typically, Hand Reader networks link to a PC using a 4-wire RS-485 (RS-422)
connection. These networks have the following requirements.
• Two twisted pair, shielded, AWG 22 wire or larger should be used (Recognition
Systems recommends Belden No. 82723 or equivalent cable).
• Hand Readers must be wired together in a “daisy chain” network from Hand
Reader to Hand Reader and then to the host PC. The total length of the wiring must
not exceed 4,000 feet per network.
• The network requires an RS-485(422) to RS-232 converter (Recognition Systems
P/N DC-102) at the PC.
