IP502: Serial Communication, 485 Half-Duplex Industry Pack Modules
These modules provide an asynchronous serial communication interface for your system. The IP502 has four asynchronous, half-duplex EIA-485 serial ports. It provides a cost-efficient interface to EIA-485 multi-driver networks which support up to 32 nodes. However, for full handshaking support, use the full-duplex IP501. Software-configuration quickly sets the baud rate, character-size, stop bits, and parity. For more efficient data processing, each serial port is equipped with16-character FIFO buffers on the transmit and receive lines. Benefi tsNon-isolated communication module with four asynchronous, half-duplex EIA-485 serial ports, 16-byte FIFO buffers.
Once you accept your quote and confirm your order, we prepare by retrieving related parts and components from our inventory. Anything we do not currently have in stock is sourced.
Upon receipt, all parts are visually inspected for damage and then photographed to document their condition. Parts acquired from vendors must meet our quality standards.
Industrial computer boards and other parts we are equipped to evaluate are tested to verify functionality and discover possible damage.
Industrial computer boards have all components with low MTBF numbers (such as capacitors and connectors) replaced and are washed in our PCB cleaner to remove dust and grime.
Industrial computer boards are fully diagnosed and repaired by our engineers. Logs of the problems encountered and solutions implemented are recorded.
Industrial computer boards have all I/O connections rigorously tested to ensure that everything is working properly before the board is certified as ready to ship.
After photos are taken to document the exterior condition of the part, it is packaged and sent to the customer. ESD-safe materials are used to protect sensitive equipment on its journey.
IPC Station is a website of GID Industrial, an ISO 9001:2015-certified company that has specialized in servicing industrial computer boards and providing other industrial products for sectors including manufacturing, defense, aerospace, entertainment, healthcare, and more by utilizing our combined skills and vast international network of trusted suppliers since our founding in 2015.
