Remote Handreader Connected To A Host Pc Via Optional Modem - Recognition Systems HANDKEY II Manual

Networking and Communications
• An unlimited number of sites can be created with up to 32 HandReaders per
site.
• The HandReaders 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 HandReader in the system. The PC collects the data
and distributes it to other HandReaders in the network.
• Access may be restricted by time and by HandReader via HandNet's access
profiles and by the use of time zones.
Typically, HandReader networks link to a PC using an 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).
• HandReaders must be wired together in a "daisy chain" network from
HandReader to HandReader 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-422 to RS-232 converter (Recognition Systems
P/N DC-102) at the PC.
Recognition Systems' optional HandNet for Windows™ software allows
programming of most of the remote HandReader setups from the computer.
However, each HandReader on the network requires the setting of an address.
HandReader addresses may be repeated, but only on different sites. Display
language, date format changes, and the communication mode must also be set
at the HandReader.
Remote An optional, internal "answer only" 14.4 bps modem is available for
HandReader HandReaders. This modem is designed for operation with United States phone
Connected to systems. Site wiring should conform to standard telephone wiring standards
a Host PC via and terminate at the HandReader with a standard RJ-11 modular phone jack.
Optional Each HandReader with a modem includes a 6' modem cable for the final
Modem connection between the phone jack and the HandReader modem. Modem
HandReaders may be networked with up to 31 non-modem HandReaders using
RS-422 wiring. Refer to the Modem Application Note (available from
Recognition Systems) for detailed information.
