Serial line RS-485

RS-485 Serial Line Interface

The MICRO-RAY circuits are each equipped with a standard RS-485 serial interface.

The communication parameters are as follows:

Mode: Asynchronous Half-Duplex

Speed: 9600 b/s

Character length: 8 bit

Parity check: None

Stop bit: 1

All the circuits are connected in the factory in a serial way to the MICRO-RAY Interface module.

Any connections between MICRO-RAY columns can therefore be carried out easily via the

interface.

Connections for RS-485 serial line

The serial connection between the various columns must be made using a shielded. The network

architecture must be of the "BUS" type, with a maximum bus length of 1200 m. If it is necessary

to use a star architecture, or the maximum length of the bus is greater than 1200 m, one or more

line-repeaters model "BUSREP" must be used.

Plugging an IP-DOORWAY to the MICRO-RAY interface it will be possible to transmit the alarms

through the Ethernet network using for example the IB-System IP product.

4 SETTING OF THE RAYS

Alignment and Verification

Each MICRO-RAY ray is equipped with an electronic alignment system, a work parameter

adjustment system and a test system, which make installation operations particularly simple and

without the need to use special tools.

It is possible to align the rays one at a time while leaving the other rays powered. In case of

disturbances or difficult in the alignment, it is possible to inhibit microwave emission of the other

rays.

Operations on TX rays

Open the column starting from the top cover, remove the screws using a crosshead screwdriver,

remove the cap (this action causes the tamper switch to open), open the cover.

• Connect the direct current power supply wires (13.8 V ) to terminals 1 and 2 of MS1 (MICRO-

RAY Interface).

• Open the tamper removing the terminal block MS1 of the TX circuit. Only the rays 2, 3, 4 (the

ray 1 tamper is already open because column tamper)

• Perform the installation / setting of the channel and the barrier number

4.1.1.1 Read/Write Barrier Number

By turn the function switch SW1 to position 8 it is possible to read and/or set the barrier number

NB: Set the same barrier number for all the rays of the same barrier.

NB1: By setting the barrier number, a default channel is automatically assigned for that barrier.

DON’T NECESSARY MODIFYING THE CHANNEL AUTOMATICALLY SET. if not

needed (see 4.1.1.2).
