Data Communications Interface, Technical Data
For HP 9000 Series 300 Computer Systems Product Number 98628A
The HP 98628A Data Communications Interface enables your workstation to
communicate with any device that is compatible with standard
asynchronous or HP Data Link data communication protocols. Devices can
include various modems or link adapters, as well as equipment with
standard RS-232-C* or current loop links.
Features
o Asynchronous Serial Communications including RS-232-C (CCITT
V.28/V.24), RS-449, RS-423, and RS-422
o Distributed System Network/Data Link support for communication to
HP 1000
o Terminal Emulation software compatibility for communication with
other computers
o Data formats of 5, 6, 7, or 8 bits/character and 1, 1.5, or 2 stop
bits
o Selectable odd, even or no parity and fixing parity bit to 0 or 1
*RS-232-C is a data communication standard established and published
by the Electronic Industries Association (EIA). Copies of the standard
are available from the association at
20001 Eye Street N.W.,
Washington D.C. 20006.
Its equivalent for European applications is CCITT V.24.
Functional Specifications
Data Rates
Standard data rates available with internal clocking:
50 75 110 134.5
150 200 300 600
1200 1800 2400 3600
4800 7200 9600 19200
Interrupt Capability
The 98628A Serial Interface Card can be programmed to interrupt the
computer on the following conditions:
Async:
o Data or control block available
o Prompt received
o Framing and/or parity error
o Modem line change (DSR, DCD, CTS, RI)
o No activity timeout
o Lost carrier or connection timeout
o End-of-line received
o Break received
Data Link:
o Data block available
o Space available for new transmission block
o Receive or transmit error
o Modem line change (DSR, DCD, DTS, RI)
o No activity timeout
o Lost carrier or connection timeout
Buffer Size
The 98628A card contains the following buffer sizes:
Async:
o Tx control is 11 blocks of 50 bytes each
o Tx data is 549 bytes
o Rx control is 99 blocks of 7 bytes each
o Rx data is 699 bytes
FDL:
o Tx control is 11 blocks of 50 bytes each
o Tx data is 549 bytes
o Rx control is 11 blocks of 95 bytes each
o Rx data is 1049 bytes
Switch Configuration
The following switches are configurable:
Async/Data Link:
Select Code: The factory setting is 20; valid select codes are 8 to
31.
Interrupt Level: The factory interrupt priority level setting is 3;
valid settings are 3 to 6.
Async/Data Link: Selects between Async or Data Link personality;
the factory setting is Asynchronous.
Note: The settings listed below are not all switch selectable.
However, all values are selectable through the CONTROL statement.
Values selected through the CONTROL statement override the switch
settings.
Async: These settings are active when the ASYNC/DATA LINK switch is
set to its ASYNC position.
Parity-Bits/Character: A 2-bit switch selects between the following
Parity-Bits/ Character combinations: None/8, None/7, Odd/7, Even/7;
the factory setting is Odd/7.
Hardware Handshake: A 2-bit switch selects:
o Handshake Off, Non-modem Connection
o Full-duplex, Modem Connection
o Half-duplex, Modem Connection
o Handshake On, Non-modem connection
The factory setting is Full Duplex, Modem Connection.
Baud Rate: A 3-bit switch selects between the following
combinations of baud rates/stops bit settings: 110/2, 150/2, 300/1,
600/1, 1200/1, 2400/1, 4800/1, 9600/1. The factory setting is 300/1.
Data Link:
These settings are active when the ASYNC/DATA LINK switch is set to
its DATA LINK position.
DID: A 3-bit switch selects the following value for the 98628's
device address: @, A, B, C, D, E, F, or G.
Baud Rate: A 2-bit switch selects the following baud rates: 300,
1200, 9600, or 19200.
Hardware Handshake: A 2-bit switch selects between:
o Handshake Off, Non-modem Connection
o Full-duplex, Modem Connection
o Half-duplex, Modem Connection
o Handshake On, Non-modem Connection
