IPIN-300 1 General Description
Hardware Manual 1
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).

Hardware Manual 7
3 Installation
3.1 Installation of the Serial IPINs
To install the IPIN-300 or IPIN-302 on a LEB base module, plug the IPIN into the LEB
connector and fix it with three screws.
The serial IPINs have only a 80-pin LEB connector. If you use a base module with a 100-pin
LEB connector, row E is not used.
The front panel may be attached just aside the base board or at the back side of the card cage.
This panel has the same size as a front panel of a single width, double high VME board, i.e.
4TE, 6HE.
The connection cable is appropriately 0.3m. For special usage, a cable with a length of 1.5m
is available.
For the address of the LEB, please refer to the documentation of the base module. I.e. the
EUROCOM-5 uses the address space $FE40.0000 to $FE7F.FFFF for the LEB.
If you use the IBAM, the base address of the IPIN module connected to X4 is $50.0000 and
X3 and X2 have the base addresses $50.8000 and $51.0000. For more information, refer to
the hardware manual of the LEB base module.
3.2 Connecting to the I/O Panel
IPIN-300:
The serial input/output connectors (X2, X3 and X4) should be connected with a double 9-pin
Sub-D cable. Six 9-pin Sub-D connectors (all channels of an IPIN-300) can be fixed at the
front panel.
As shipped, the IPIN-300 has a configuration as a RS232 interface. For other usage, the IPIN
can be arranged (see Chapter 4 ‘Configuration’) in different ways.
IPIN-302:
The IPIN-302 uses a 26-pin connector for all isolated I/O lines. It should be connected to the
IPIN-303 via a 26-pin flat cable.
The IPIN-303 mounting panel can be used as I/O for up to two IPIN-302 (12 I/O channels).

4.1 The Configuration Array of IPIN-300
The IPIN-300 can be configurated for synchronous or asynchronous serial data transfer.
The next figure shows the position of all jumpers. On the soldering side, pin1 is marked by a
bevelled corner.
Figure3: Jumper Location Diagram (Bottom View)
Normally the pins6 and 18 of the serial I/O connectors SIOC (X2, X3, and X4) are used for
the DSR signals of each channel. For a synchronous data transfer, these pins may be used as
clock input or output signals. Pin18 is used for channelA and pin6 is used for channelB of
each SCC.

4 Configuration IPIN-300
10 Hardware Manual
DSR can only be used in asynchronous mode as input. In synchronous mode, SCC allows this
pin only as SYNCH output, so the signal DCD of channelB is used as DSR input of
channelA.
The following table shows the connection between the function of each SCC and the
configuration of his jumper field.

4.2 The Configuration Array of IPIN-302
The IPIN-302 can be configurated for different opto-coupler and data transfer options. The
next figure shows the jumper location of the IPIN-302.
Figure4: Jumper Location of IPIN-302 (Bottom View)
• Jumpers J301 and J302: Opto-Coupler Configuration
These jumpers are used to connect pin8 of the opto-coupler to Vcc or GND (Vaa or AGND).
They have to be configurated as shipped. Do not change these jumpers!

4 Configuration IPIN-300
12 Hardware Manual
• Jumper J401 to J406: TD/RD - Selection
For differential data transfer (RS422) the pins3 and 4 of the 6-pin modular jacks of the
IPIN-303 are used for the inverted receive and transmit signals. For asymmetric data
transfer (RS232) these pins must be connected to signal ground.
4.3 The Configuration Array of IPIN-303
The IPIN-303 can be used as I/O connector board for up to two IPIN-302 modules.
Each modular jack has a jumper to connect pin1 and pin6 (RDYin - RDYout) and a resistor
to terminate the receive data lines (RD+ and RD-) for RS422 applications. As shipped, the
jumpers are open and the resistors are not inserted.
