TEV-IBx Boards
The TEV-IBx are interface boards. Two boards are supplied by Tibbo:
- TEV-IB0: RS232/422/485 serial port board (each EM1000TEV has two of them);
- TEV-IB1: Three opto-input and three relay output board (each EM1000TEV has two of them). Opto-inputs optionally can 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 EM1000TEV system has four interface boards and each board is controlled through one of the four serial ports of the EM1000 module.
