1 General Description
The IPIN-300 and IPIN-302 are single Intelligent Peripheral INterface (IPIN) modules for use
in connection with an ELTEC Local Extension Bus (LEB) base module.
The most important features of these IPINs are:
•Three Zilog Z8530 8MHz serial communications controllers (SCCs) for six high-speed,
multi-mode, multi-protocol channels with program control.
•In asynchronous mode, each channel is programmable for five to eight bits per word with
one, one and one-half, or two stop bits. The user can also select odd, even, or no parity.
•Programmable baud rate generators and digital phase-locked loops for clock recovery for
50bps up to 115 200bps in asynchronous x16 mode.
•In synchronous mode, you can select external or internal character synchronization on one
or two characters, CRC generation and checking with CRC-16 or CRC-CCITT, present to
either 1s or 0s.
•Each SCC has also an SDLC/HDLC mode with comprehensive frame-level control,
automatic zero insertion and deletion, I-field residue handling, abort generation and
detection, CRC generation and checking and SDLC loop mode operation.
•Multi-protocol operation under program control; programmable for NRZ, NRZI, or FM data
encoding.
•Vectored interrupt support with three different vectors per channel for transmit, receive, and
status interrupt sources.
•Software driver for OS-9 and UNIX, for other operating systems sample drivers available.
•In connection with an IBAM board, the user has up to 18 multi-mode high-speed serial I/O
channels in a single VME slot.
Special features of the IPIN-300:
•0 to 2Mbps in synchronous mode.
•RS232 / V 24 (X.21 bis) full modem control with a 9-pin IBM compatible Sub-D connector.
•RS422,485 / V 11 (X.21) converter available.
•500mV pico fuse to protect 12V supplied chips.
Special features of the IPIN-302:
•On-board level converter for RS232 or RS422.
•Opto-isolated channel, 500VDC isolation voltage against system, not between channels.
•Only RxD and TxD supported.
•Front panel with 12 x 6-pin modular jack for two IPIN-302s available (IPIN-A303).
