Omron’s 3G2A5-LK201-EV1 host link unit is engineered for streamlined communication between devices. It operates using RS-232C and RS-422 communication interfaces, providing flexibility in transmission methods that can be configured as half-duplex or full-duplex. The unit can accommodate various baud rates: 1200, 2400, 4800, 9600, or 19200 bps, allowing it to adapt to specific network requirements.
Data can be formatted in either 7-bit or 8-bit ASCII to suit diverse communication needs. The host link unit includes two communication ports, with Port 1 configured for RS-232C and Port 2 capable of RS-232C or RS-422 connectivity, enabling connections for up to 32 devices when utilizing the RS-422 interface.
For improved reliability, the unit implements error detection mechanisms, such as vertical parity (even or odd) and FCS checksum. Maximum transmission distances are specified as 15 meters for RS-232C and up to 500 meters for RS-422, offering robust connectivity across various setups.
The power requirements include a 5V DC output for optical interfaces, while CTS signal control is supported for both available ports. Additionally, the device comes with a wrap communication test feature accessible via a DIP switch, allowing for quick diagnostics.
Status indicators such as RUN, Error (ERH, ERC), Send (SD), and Receive (RD) provide immediate feedback on the operational state of the unit, facilitating easier monitoring. For customized settings, DIP switches offer a straightforward configuration method, allowing users to adapt the host link unit's parameters easily.
