3560 Extended Communication Module
This section explains the features and operation of the optional 3560 Extended
Communication Module.
14.1
Description
The 3560 is an add-on module that extends the communication capabilities of
the 1560. First, it provides a GPIB (IEEE-488) interface. With this interface a
system controller can remotely operate the 1560 and read measurements
through an IEEE-488 bus. The Centronics printer interface allows the 1560 to
connect to a printer. The 1560 can then be programmed to print out measure-
ment data in real time. Measurements previously acquired and stored within the
1560 can also be printed. The 3560 also provides an analog output. This output
sources a voltage that represents the value of measurements. The analog output
can be connected to a strip-chart recorder for a graphical plot of temperature
over time. Finally, the 3560 also adds a second RS-232 serial port. This can be
used as a bi-directional communication interface or as a serial printer interface
for the printing out of data.

Specifications
See Table 30 on page 164.
14.3
Installation
The 3560 Extended Communication Module attaches to the back of the 1560
system as any other module. For instructions on installing modules onto the
1560 see Section 4.1. Since the 3560 Module has connectors placed on the
back it must be installed as the last module in the stack.
Once the 3560 is installed onto the 1560 the 1560 will automatically recognize
the Communication Module and the functions it provides. Five devices are
added: the GPIB Communication Device (GPIB), Serial Communication De-
vice (SERC), Serial Printer Device (SERP), Parallel Printer Device (PARP),
and Analog Output Device (AOUT). These devices will appear labeled as indi-
cated with the appropriate soft-key functions. The operation of each device is
explained in the following sections.
14.4
GPIB Communication Device
The GPIB (IEEE-488) interface allows the 1560 to be connected to an
IEEE-488 bus along with other instruments. A system controller can remotely
control the operation of the 1560 and read measurements.
