Matrix IV EHT Metal
EM-Marine / HID ProxCard II / Atmel (T5557) 125kHz RFID Reader
with connection via iButton (1-Wire) / Wiegand-26/42 protocols
1. OVERVIEW
Matrix IV EHT Metal Reader is used in Access Control Systems (ACS). The reader transfers EM-
Marine, HID ProxCard II or Atmel (T5557) token codes into controller, via iButton (Dallas Touch
Memory) or Wiegand-26/Wiegand-42 protocols.
Special features:
- Reader can distinguish the original ID cards from their cloned copies. This allows to disable
transferring the numbers of cloned cards into controller, at the reader level. Such reading mode is
dubbed "anti-clone".
- Reader case is made of Silumin for increased anti-vandalism protection.
2. MOUNTING AND CONNECTION
The reader should be mounted on a flat surface at a place where proximity cards can directly
approach the reader (see Figure 1).
To mount the reader, perform the following steps:
- Unscrew the screw at the bottom of the case and remove the back lid.
- Apply the back lid to the wall, to mark mounting holes locations.
- Drill the holes.
- Screw the back lid to the wall.
- Mount the reader and attach it with the screw at the case bottom.
- Connect the wires as per Table 1.
- To select the protocol for data transfer to controller, connect DATA0 and DATA1 wires as per
Figure 2.
- Insulate all the wires junctions.
- Power on the reader and verify its proper operation by touching it with a card.
Notes:
1. Do not install the readers within 10 cm from one another.
2. To work at specified line distance to controller, please use a UTP cable (e.g. a CAT5e cable).
- When connecting via iButton, one wire of a twisted pair connects to GND and another to DATA0
terminals.
- When connecting via Wiegand, first twisted pair connects to GND and DATA0, and the second
to GND and DATA1 (See Figure 2).
