AS01367 Serial Gateway
DeviceNet™ to RS422/485 Interface
The AS01367 is a compact RS422/485 to DeviceNet™ serial gateway. The unit is housed in a 21/2 x 31/4 inch plastic housing with mounting tabs. A 5 pin micro connector provides the DeviceNet™ interface and a 9 pin D connector provides the RS422/485 interface. The DeviceNet™ channel is fully isolated from the supplied power.
The AS01367 may be used to interface peripheral devices to a DeviceNet™ system. The RS422/485 serial stream is internally buffered, allowing a Master node to send and receive data using standard DeviceNet™ messaging.
The power is conditioned by a loss-of-ground protection circuit and applied to a non-isolated DC-DC converter to provide 5 volts @ 500 mA. An isolated DC-DC converter provides power to the DeviceNet™ channel.
AS01367 provides a fully buffered serial interface between DeviceNet™ and peripheral devices. Internal FIFO's, buffer up to 256 bytes of receive and transmit data, easing the interface to slower RS422/485 based devices. Hardware or software flow control is supported.
The AS01367 replaces the CDN367 and is backwards-compatible.
