Communications
HandPunch/host computer communications can be configured in one of three
ways:
•
via a direct RS-232 connection
•
via a direct RS-422 connection using a data converter
•
via an optional Ethernet network connection (one HandPunch terminal
must have the Ethernet communication option installed)
•
via an optional Modem connection (one HandPunch terminal must have
the Modem communication option installed)
A direct HandPunch connection to a host computer can be made through an
4-conductor cable in an RS-232 serial configuration. A 6’ or 50’ cable may be
purchased through Schlage Biometrics or a wiring diagram for the RS-232 to
host computer connection is found on “Table 4” on page 33.
If you make the RS-232 to host computer connection you cannot use the serial
printer option (see page 21).
A direct HandPunch network connection to a host computer can be made
through a shielded, 4-conductor cable in a full-duplex RS-422 configuration.
An RJ-11 jack must be installed within 6 feet of the host computer. Position
the RJ-11 jack using the template provided in this manual (see “Figure 3-2” on
page 25). The HandPunch RS-422 network is connected to this jack.
A data converter (Schlage Biometrics P/N: DC-102) is required to connect the
host computer to the RS-422 HandPunch network. The DC-102 is connected
to an available RS-232 serial port on the computer. Then connect the DC-102
to the RJ-11 jack using the 8 foot cable provided with the DC-102. A wiring
diagram for the RS-422 to host computer connection is found on page 31.
A HandPunch communication network is then connected, unit-to-unit, via an
RS-422 “daisy-chain” network. A network RJ-11 jack is installed on or in the
wall behind each terminal. Each RJ-11 jack is then interconnected in daisy-
chain fashion using two, twisted-pair, AWG22 wires (Schlage Biometrics
recommends using Belden No. 82723 cable). The daisy-chain network can
extend up to 4,000 feet in length, and can have up to 31 HandPunch terminals
connected to it.
Connect the HandPunch terminal to the RJ-11 jack using the short silver cable
provided with the terminal.
