This Quick Start Guide is intended for experienced installing technicians. It is a basic reference to ensure all connections are properly
made. Models include EM-30-OSDP, EM-50-OSDP, and EM-64-OSDP. For additional information please reference Farpointe Data’s
website, www.farpointedata.com.
1.0 Introduction
A key component of a physical security electronic access control
system, a proximity card reader is based on RFID technology. In
operation it is capable of reading data stored on a proximity credential
via radio frequency and without physical contact, and then passing the
data obtained to the physical access control system. Access control
systems typically manage and record the movement of individuals
through a protected area, such as a locked door.
2.0 Mounting Provisions
Each reader may be installed either indoors or outdoors. Mounting
options shown in the table below. Use supplied #6 mounting screws,
or equivalent security screws, for installation.

3.0 Cable Requirements
Cable, 4 conductor, 22 or 24 AWG [65 mm or 51 mm] twisted pair,
over-all shield and UL approved (Belden 8723, or equivalent).
Maximum bus length: 4,000 ft – 24 AWG (1,219 m)

5.0 Output Formats
The SIA standard OSDP protocol is supported for clear and secure
channel communication.
Default Address: 0
Default Baud rate: 9600bps (bits per second)
Default Secure Channel Key:
SCBK_D = 0x303132333435363738393A3B3C3D3E3F.
OSDP Protocol Technical Support:
SIA OSDP Application Profile: Basic Reader (OSDP v2.2 and higher)
6.0 Grounding
Shield (drain) continuity must run from the reader to the access panel.
Shield (drain) and reader ground must be tied together at the access
panel and connect to an earth ground at one point.
7.0 Power
Reader may be powered by the access panel. A linear power supply is
recommended for best operation.
8.0 Voltage and Current
Voltage: 5 to 16 VDC
Current Draw: 70mA to 120mA
9.0 Read Mode
Reader (OSDP “PD”) operation is controlled by the access panel
(OSDP “ACU”) per the OSDP specification.
10.0 Connection
Connection must be done in accordance with NFPA 70. Do not
connect to a receptacle controlled by a switch. Connect to a power
limited DC voltage source.
11.0 Troubleshooting
1. When the reader is first powered on it will beep 4-times.
2. Presenting a supported access credential will result in the
reader beeping once.
3. OSDP communications with the panel will be established after the
reader has completed its start-up sequence. The panel can query
the reader for status using OSDP commands. Note, at this point,
the access panel controls the reader beeper and LED functionality.
If the reader does not recognize the card or tag (no beep, no LED
flash), refer to possibe OSDP communications errors detected at the
access control panel. Please see the following table for additional
possible causes and solutions.
See additional troubleshooting information on reverse.
