Introduction
Serial Communications
The ZT 8832 includes two asynchronous serial communication
channels, each with a programmable baud rate generator. The V40
provides one serial channel with an architecture similar to the
asynchronous portion of the 8251. Configured as RS-232 DTE, this
serial channel supports transmit data (TxD), receive data (RxD), and
ground. These signals are available through a 3-pin frontplane
connector. The optional 1 meter ZT 90069 cable is available to
connect the 3-pin connector to a male 25-pin D type connector.
The second serial channel (Intel 82050, or equivalent) is functionally
equivalent to the serial controller used in the IBM line of personal
computers. This channel supports all handshaking and modem control
signals and can be jumper programmed for RS-232 or RS-422/485.
Other features include loopback diagnostics, maskable interrupt
generation, and jumper selectable DCE or DTE configuration. The
82050 serial channel is accessed through a 14-pin frontplane
connector. The optional 1 meter ZT 90014 and ZT 90027 cables
connect the 14-pin connector to a male or female 25-pin D type
connector, respectively.
Parallel
Input/Output
There are three 8-bit parallel ports on the ZT 8832, for a total of
24 I/O lines. Each I/O line can be programmed as input or as output
with readback. The I/O signals, fused power, and ground are
accessible through a 26-pin frontplane connector. The optional
1 meter ZT 90068 cable is available to connect the 26-pin connector
directly to an 8-, 16-, or 24-position I/O module mounting rack, such
as Ziatech’s ZT 2226 or the rack offered by Opto 22.
