Tews TIP865
Industry Pack	PowerPC	v. 4.0
Multiport Serial I/O

Tews' TIP865 is an IndustryPack®-compatible module with four channels of high-performance multimode serial interface.

The TIP865-10 offers four RS232 interfaces, the TIP865-11 provides four TTL interfaces, the TIP865-20 supports four RS422 interfaces, the TIP865-30 provides four RS485 multidrop interfaces and the TIP865-51 offers two RS422 and two RS485 interfaces.

The full modem control is available for each of the four serial interfaces on the TIP865-10 and -11 supporting RxD, TxD, RTS, CTS, DCD and clock. The TIP865-20 provides RxD, TxD and clock. The TIP865-30 supports a bidirectional RS485 bus.

The TIP865-51 is a combination of the TIP865-20 and TIP865-30. Two channels support RxD, TxD and clock for the RS422 interface and two channels supports a bi-directional RS485 bus.

Features include programmable baud rates to 2 Mbit/sec, asynchronous or synchronous protocols including NRZ, NRZI, FM, T1, SDLC/HDLC.

The maximum baud rate of the TIP865 is affected by several options like the clock input source, clock frequency, used clock mode, synchronous or asynchronous serial mode and the on board physical transceiver.

The communication controller used is the industry-standard Z85C30.
