3.2 Wiring the Readers
3.2.1 Wiegand
Each reader port supports one or two readers (entry and exit readers) with
Wiegand output format. The maximum power draw is 500 mA for readers
and AUX Power combined.
To fully utilize each reader port, a shielded 8-conductor cable (18-24 AWG)
is required. You can use standard FTP cable with RJ45 plug 8-wire CAT
5E/6E/7 (recommended) 6-conductor cable (HAS part number
NC186-BL).
Note:
If you are using HOLD lines for readers, this signal is standard
included in the RJ45 reader connectors.
The cable is shielded and grounded at the panel. Grounding at both ends
can cause ground loops which can be disruptive. The maximum
recommended length of wiring is 50 m (150 feet) per reader.

attached to the reader ports for Door 1 (J11, J10).
3.2.2 OSDP
The MPA2 Access Control panel also supports OSDP readers. OSDP (Open
Supervised Device Protocol) is a bi-directional RS485 Multi-drop AES128
Encrypted protocol.
The MPA2 provides 2 separate OSDP ports, one for DOOR1 and one for
DOOR2. Each port can have 2 OSDP readers connected (Address 00 =
Entry reader and Address 01 = Exit reader).
The OSDP readers are connected through CAT7 S/FTP RJ45 cable (See
). The (OSDP) bus (TRX+, TRX-, 12V, GND) supplies standard 12V
for the readers.
The maximum power drawn is 500mA for the readers including AUX power.
The maximum recommended length of the OSDP readers wiring is 150 m
(500 feet) per OSDP port.

Notes:
• Make sure your MPA2 DIP switch settings (SW1, S1) are set correctly
for corresponding Wiegand and/or OSDP reader usage.
