Installation of a Serial Reader
Required Materials
•
A standard one-to-one connection RS-232 cable (computer
modem cable) of sufficient length to connect the Reader to any
device that accepts RS-232 as input. The length required for your
installation will vary. One end needs to be a DB9 male connector.
IMPORTANT!
DO NOT use a null-modem cable or a null-modem
adapter.
Connecting the Serial Reader to a Computer or Device
Step 1:
Attach the female end (it can be either DB25 or DB9
according to the device serial connector) of the cable to
the third-party device. Connect the DB9 male end to DB9
female connector on the Reader.
Step 2:
For the third-party device, configure the communications
port settings to the following:
Baud Rate
4800
Data Bits
8
Parity
None
Stop Bits
1
Flow Control
None
The Reader is a DCE (Data Circuit-terminating Equipment)
device, and data is output through a DB9 female RS-232
connector. Only the following pin assignments are used:
•
Transmitted Data (pin 2)
•
Received Data (pin 3)
•
Signal Ground (pin 5)
Note: Although the Serial Reader has a terminal block
labeled with Wiegand Data Zero, Data One and Ground, it
cannot be used to connect to a Wiegand control panel.
Step 3:
Apply power to the Reader. See section
