Page 6: Product Description
Product Description IP-OCTAL-422 is part of the Industry Pack™ family of modular I/O components. It is based around the Signetics CMOS SCC2698 Octal Universal Asynchronous Receiver/Transmitter. This component provides eight channels of full-duplex asynchronous serial communications, baud rate generators, state change detect logic, and four 16-bit counter/timers. - Page 7 The IndustryPack is controlled by a single CMOS 22V10 type PAL. Connection to the IP-OCTAL-422 is via a standard 50-conductor ribbon cable. An optional connection panel is available which provides a 50-pin flat cable input with 16 DB- 9 male or female connectors. The metal reinforced connection panel mounts in a standard 19 inch rack-mount space.

Page 8: Vmebus Addressing
IP-OCTAL-422 is accessed using 8-bit bytes at odd locations only. It is usually accessed in the I/O space. Shown below in Figures 2 and 3 are the register maps of the IP-OCTAL-422. All addresses are offsets from the I/O base address of the IP as set on the IP carrier board. -

Page 10: Nubus Addressing
NuBus Addressing Since the Nubus uses only 32-bit wide accesses, 8-bit wide peripherals such as the IP- OCTAL-422 appear in the host address space every fourth byte. To calculate the RM1260 Springboard register addresses from the VMEbus address (given in the previous section in Figures 2 and 3), multiply by two and subtract one. To convert VME addresses to RM1270 SupportBoard addresses multiply by two and add one. -

The five lines are Ground, Transmit Data output Minus, Transmit Data output Plus, Receive Data input Minus, and Receive Data input Plus. The common ground line for all channels connects to the local logic ground.

Page 15: Programming
Programming The IP-OCTAL-422 is designed around the SCC2698B and all of the SCC2698 functions are available. The SCC2698B is divided into four Functional Blocks lettered A through D. Each functional block contains two serial channels. The channels are identified by lower case letters a through h. -

IP. If a driver requires that a particular revision be present, it may check for it directly. Standard data in the ID PROM on the IP-OCTAL-422 is shown in Figure 7 below. For more information on IP ID PROMs refer to the IndustryPack Logic Interface Specification, available from SBS. -
Page 17: User Options
Figure 8 Strobe Connection Options The IP-OCTAL-422 is configured to support minimum Direct Memory Access (DMA) on Channels C and D. To use DMA, program the SCC for TxRDY or RxRDY on MPOc and/or MPOd. See Figure 9 below for DMA Shunt Assignments. -
Page 18: Construction And Reliability
Construction and Reliability IndustryPacks were conceived and engineered for rugged industrial environments. The IP-OCTAL-422 is constructed out of 0.062 inch thick FR4 material. The six copper layers consist of a ground plane, a power plane and four signal planes. Surface mounting of components is used extensively. IC sockets for the control PAL and ID PROM use gold plated screw-machined pins. -
