• Extended temperature version available for harsh industrial environments.
1.2 Board Overview
The PB-SIO4A has two connectors for interfacing to the carrier board. Connector ST101
interfaces to the CPU side of the carrier board whereas connector ST102 provides interfacing to the external interface side of the carrier board.
ID 19958, Rev. 0300 Page 1 - 3® PEP Modular Computers GmbH
PB-SIO4A Introduction
This piggyback is fitted with DUART devices (two driver/receiver devices each handling
two of the four serial channels), as well as a GAL device containing the specific interrupt
handling logic and other features such as the I.D. number.
The optoisolated versions have eight optocouplers which are replaced with wire bridges
on the non-optoisolated versions.
For operational configuration of this piggyback there are solder jumpers located both on
the front and rear side of the board.

1.4 PB-SIO4A External Interfacing
Connection of the PB-SIO4A piggyback to external devices is a function of the specific
carrier board for the piggyback. In conjunction with the carrier board there are various
possibilities for connecting the I/O channels of the piggyback to external devices.
For the carrier boards themselves there are three types of connectors available.
Front Panel:
• 50-pin male, double row, flat-ribbon cable connector, locking
• 50-pin female, Dsub connector
I/F LOGIC
On-Board:
• 50-pin male, double row, flat-ribbon cable connector head
In conjunction with the carrier board’s connectors, there is also the possbility of providing connection to external devices using the AD-SIO4 adapter. This adapter utilizes
either of the carrier board’s flat-ribbon connectors to provide 4, 15-pin female, Dsub connectors. One connector for each channel of the PB-SIO4A. Two PB-SIO4A’s and two of
these adapters can be combined to provide 8 serial I/O channels. The AD-SIO4 is
optional and must be ordered separately. See chapter 4 of this manual for a description
of the AD-SIO4.

3.1 PB-SIO4A Address Map and ID Byte
The PB-SIO4A is addressed (odd byte access) by using the carrier board base address
and one of the following offsets for the piggyback location:
Piggyback location A ( the upper position on the carrier board)
Base Address + $01 DUART1
Base Address + $21 DUART2
Base Address + $41 ID Byte
Piggyback location B ( the lower position on the carrier board)
Base Address + $81 DUART1

Base Address + $C1 ID Byte
The PB-SIO4A has an ID Byte of $E7 (RS422/RS485).
3.2 VMEbus Interrupts
Each DUART device is able to issue an interrupt request (*IRQ) to the carrier board. In
the event of simultaneous interrupt requests those from DUART #1 have priority over
those from DUART #2.
The interrupt level is set by the carrier board. See the carrier board documentation for
setting of the level. The interrupt vector itself is provided by the DUART.

PB-SIO4A Adapter AD-SIO4
4. Adapter AD-SIO4
4.1 Product Overview
The AD-SIO4 is a special adapter designed to provide front panel connection to the PBSIO4A using 15-pin Dsub connectors as opposed to the 50-pin connector provided by
the carrier board.
This adapter consists of a separate, 8 HP front panel with four, 15-pin female Dsub connectors mounted on the front side for external device connection, and two, 24-pin, male
dual row connectors for internal connection to the PB-SIO4A carrier board. Connection
from the carrier board to the adapter is done via a 50-way, flat band cable with a 50-pin
dual row female connector for the carrier board, and two, 24-pin dual row female connectors for connection to the adapter. This cable allows for the connection of two PBSIO4A’s to two AD-SIO4’s where pins 25 and 26 are not used. See Table 3-4 for the
pinout of this cable.
