HP-PB 16-Channel Asynchronous Multiplexers, Technical Data Product Numbers HP J2092A, J2093A, J2094A The 16-channel Asynchronous Multiplexers provide a means to connect up to sixteen asynchronous serial devices to PA-RISC HP9000 Series 800 Computers which use the HP-PB (Hewlett-Packard Precision Bus) as their primary system input/output bus (8x2 and 8x7 Series ) and have HP-UX operating system version 8.0 or later installed. Based on on-board microprocessor and memory, the Multiplexer handles data transmission and control, inbound and outbound traffic flow control, and modem signals control. It is thus an intelligent and powerful IO card freeing the system CPU of traffic overhead and guaranteeing data integrity and no character loss. The 16-channel multiplexers provide one of the following solutions: J2092A: 16 RS-232-C compatible ports for direct connection J2093A: 16 RS-423-A compatible ports for direct connection requiring long distance cabling J2094A: 16 RS-232-C compatible ports for direct and remote connection with support of full duplex modem control A wide range of configurable transmission modes and formats permits hardwired and remote connection of various CRT terminals, printers, plotters, and other asynchronous devices. Features Feature set common to the three products: o Programmable data-rate for each channel o Programmable character size: 7 or 8 data bits o Programmable number of stop bits: 1 or 2 o Parity, overrun, framing error check detects transmission faults o Break detection and generation o Automatic and programmable device XON/XOFF handshaking to pace MUX input and output data transmission o Programmable parity: odd, even, or none o On-board buffering to send/receive data to/from host for multiple ports o Firmware based self tests executed at "power-on" o A customer diagnostic utility is available to verify hardware/software and data path integrity for each port with the use of loopback hood supplied with the product o Online diagnostic tools are also available to support engineers to troubleshoot the card Features specific to the J2092A product: o EIA RS-232-C and V24/V28 compatibility for data only connections (no modem control) on default DB-25 female standard connectors provided with the product, or on customized connection scheme o Line speed up to 38.4 kb/s o Remote support of the card is possible through the use of the diagnostic tools. Features specific to the J2093A product: o EIA RS-423-A and V10 compatibility for data only connections (no modem control) on the default DB-25 female standard connectors provided with the product, or on a customized connection scheme. This allow the operation of RS-423 & RS-422 devices such as HP terminals (HP700/32, HP700/92, HP700/94, HP2392A) and HP printers (HP LaserJets) at distances up to 1200m. o Line speed up to 38.4 kb/s Features specific to the J2094A product: o EIA RS-232-C and V24/V28 compatibility for connection of terminals, modems, or serial printers on DB-25 standard connectors. o All lines support full-duplex modem control (8 signals per channel) which permit point-to-point dialup or leased line operation. . o Three types of modem protocol are supported: - Bell protocol, 2 signals: DTR and DCD - CCITT protocol,6 signals: DTR,DCD,DSR,RTS,CTS,RI - No protocol, user can handle 8 signals (4 input/4 output) o Line speed up to 19.2 kb/s. o Hardware flow-control capability through the use of CTS/RTS signals. o Remote support of the card and connection panels is possible through the use of the diagnostic tools. Functional Description The 16-channel Asynchronous Multiplexers comprise three major functional assemblies: o The MUX card: A single width HP-Precision Bus card that interfaces with the system backplane o Two "distribution panels" (8 ports each) offering standard DB-25 connectors for peripheral attachment. For the J2092A and J2093A products, they are known as "Direct Distribution Panel - DDP." For the J2094A product, they are known as "Active Distribution Panel - ADP II." These distribution panels can be rack mounted in standard 19" bays. (Refer to the section "related products" of this data sheet for more details) Optionally, these distribution panels can be removed for the direct connect multiplexers - J2092A, J2093A - thus allowing the MUX to be linked to any type of connectors or cabling scheme (i.e. RJ11, RJ45, punch panels, data switches...). See "functional specification" section of this data sheet for connector pin-out. o The link cable between the MUX card and the distribution panels (4 meters). At the heart of the HP 16-channel multiplexers is a circuit card that contains a 68000 microprocessor and associated PROM and RAM memory. The 128 Kbyte PROM contains the power-up self-test and system support code. The code downloaded from the host is stored in the 256 Kbyte RAM. Download operation and card diagnostics are performed through a special supervisor on-card buffer. Functional Specifications Buffering: On-card buffering to send/receive data for multiple ports to increase throughput and reduce host CPU load. Transmit Buffer Size: 255 bytes per port Receive Buffer Size: 511 bytes per port Software: HP 9000 Series 800 HP-UX revision 8.0 or later Communications Signals available on the DB-25 connectors of either the DDP or ADP II for the RS-232-C products. ________________________________________________________________________ Input/ Connector Connector RS- V.24 Abbrev.

In addition, 38400 bits/s is supported with J2092A and J2093A products. ________________________________________________________________________ cross talk between pairs bits/sec meters/(feet) 1 volt (RS 423 recommendation) 0 to 38400 300/(1200) 2 volts (with HP peripherals) 0 to 19200 1200/(4000) 38400 300/(1200) ________________________________________________________________________ Note regarding the J2093A product: The maximum baud rates/distances supported are the following: Throughput: The 16-channel Multiplexer hardware and firmware is able to support an inbound data throughput of 19.2 K baud simultaneously on each channel (or 38.4 K baud simultaneously on 8 channels), without character loss when flow control is activated, or an outbound data throughput of 19.2 K baud simultaneously on each channel. However, the global system performance of the system is dependent on the customer application and on the HP 9000 HP-PB Series 800 computer load and performance. Communication Mode: Bit serial, asynchronous. Break Detection and Transmission: Break condition is recognized by the interface, and message is sent to the host. Break condition can also be generated by the MUX at the request of the host. Device Handshakes: The MUX is capable of pacing both inbound an outbound data via an "XON/XOFF" type of protocol. The "XON/XOFF" characters are programmable. The host may program the MUX card to automatically manage "XON/XOFF" flow control, thus avoiding any character loss. The "XON/XOFF" may also be under application control, but no data loss is guaranteed only if the MUX is responsible for flow-control. In the J2094A product, in addition to the XON/XOFF flow control mode, inbound and outbound data flow can be managed by the MUX card through the use of CTS/RTS modem signals. Edit Functions: Edit functions such as backspace, character delete, and line delete are passed to the host and managed by the host operating system.
