The TEV-IBx are interface boards. Two boards are currently supplied by Tibbo:
| • | TEV-IB0: RS232/422/485 serial port board (each EM1000-TEV system has two of them); |
| • | TEV-IB1: 3 x opto-input/ 3 x relay output board (each EM1000-TEV system has two of them). Opto-inputs can optionally be used to connected a Wiegand or clock/data reader. |
TEV-IBx Board Connector
The TEV-IBx boards are connected to the TEV-MB0 motherboard through a 2x10-pin connector. Each two pins of the connector are combined together for better electrical contact. Therefore, the connector effectively has 10 lines.
Each EM1000-TEV system has four interface boards and each board is controlled through one of the four serial ports of the EM1000 module.
