Bidirectional pass counter v.1.x

Description

The counter consists of two modules:

• emitter - with one LED in the middle of the front panel (Fig. 1).
• receiver - module with LED in the middle of the front panel and two holes on the edges of the front panel (Fig. 2). Also on this module top you can find a narrow hole to access the button to activate the WiFi setting mode (Fig. 3).

Both units have a rectangular hole for the power cord at bottom side (Fig. 4).

Installation

1. Connect the power cords to the modules. If you connect the emitter power is necessary to observe the polarity ( "+" - near the wall, Fig. 5).
2. Fix the modules on both sides of the aisle at a height of 1.20 — 1.40 meters. The receiver must be placed horizontally (to account for the direction of the input/output).
3. Connect the power supply.
4. The efficiency of the emitter can be checked using the smartphone camera. When viewed from the front side on the emitter LED from a short distance through the smartphone's camera, LED of running emitter will be painted in red-blue/purple color (Fig. 6).
5. Receiver LED will flashing red and/or green in the different modes:
   • Normal: the green every 5 seconds and/or at the intersection of the beam visitor;
   • Setup mode: the green 10 Hz;
   • Overlap beam: frequent blinking red (~ 10 Hz). The mode is set when there is no signal from the transmitter for 25 seconds;
   • There is no WiFi network: the red every 5 seconds.

WiFi Setup

All devices use the same WiFi Setup procedure. The difference is in where placed and how the init setup button looks. At the pass counter receiver:

version 2: the top has a narrow hole to access the button to activate the WiFi setting mode (Fig. 3). Button is pressed with a toothpick. Sometimes an angle. When pressed felt (not heard) a click.

version 3: the button is inside the hole under three diods on the front of receiver.

WiFi Setup

Setting and checking the operation of the device

1. Go to the page at https://baozam.net
2. In the "Inventory" section, select the desired device.
3. Over the device page, click on the link «Tuner». When the next transfer data to the cloud the device will go into the settings mode.
   • The device sends data to the cloud every five (5 minutes). The device immediately reports about cutting/opening the beam, turning on. To avoid to wait up to five minutes, you can: a) cut off the beam - a message in 25 seconds, b) turn off/on the device.
   • After the device come into the setup mode you will get a message at the «Tuner» page, and all device parameters will be displayed.
4. Hovering the cursor over the "blue" parameter causes the appearing of «Stream & Monitor» buttons.
   • Stream - on/off sending this parameter to the cloud.
   • Monitor - on/off immediate displaying parameter in the "Monitor" box at the page.
5. You should check
   • Entering the emitter beam on the receiver sensors (parameters «left sensor» & «right sensor»). Turn on sensor monitors. Normal values ​​range 5 - 6. If the reading is less than 5, the emitter and receiver are not aligned or something overlaps the beam. Adjust the alignment, clean the beam path. If values are ​​greater than 7 look for the source of noise.
   • The direction of the entrance/exit. By default, the input direction is from left to right relative to the receiver. Turn on monitoring parameter «count_in_tmp». Cross the beam ... change the direction by using the «Mode Control» button. Use the drop-down button «LEFT to RIGHT is ENTER» or «LEFT to RIGHT is EXIT» to select the desired direction.

   Important! If you change the direction of the passage, be sure to save your changes («Settings» button - «Save»). Otherwise, when you turn off the device power your settings will be lost.
