FOR YOUR SAFETY
Before undertaking any troubleshooting, maintenance or exploratory procedure, read carefully the
WARNINGS and CAUTION notices.
This equipment contains voltage hazardous to human life and safety, and is capable of inflicting
personal injury.
If this instrument is to be powered from the AC line (mains) through an autotransformer, ensure the
common connector is connected to the neutral (earth pole) of the power supply.
Before operating the unit, ensure the conductor (green wire) is connected to the ground (earth)
conductor of the power outlet. Do not use a two-conductor extension cord or a three-prong/two-
prong adapter. This will defeat the protective feature of the third conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with power applied
and protective covers removed. Read the procedures and heed warnings to avoid “live” circuit
points.
Before operating this instrument:
1. Ensure the instrument is configured to operate on the voltage at the power source. See
Installation Section.
2. Ensure the proper fuse is in place for the power source to operate.
3. Ensure all other devices connected to or in proximity to this instrument are properly grounded or
connected to the protective third-wire earth ground.
If the instrument:
-fails to operate satisfactorily
-shows visible damage
-has been stored under unfavorable conditions
-has sustained stress
Do not operate until performance is checked by qualified personnel.

User Manual 1260-14C
Module Specification 1-1
Chapter 1
MODULE SPECIFICATION
Module
Specification The 1260-14C provides 96 Open Collector (OC) I/O lines in twelve
groups of 8 bits each. Each group of 8 bits (hereafter referred to
as a port) can be read from or written to asynchronously using the
commands READ and WRITE. Additionally, up to 12 ports may
be grouped together and synchronously operated using an
external clock for as many as 256 consecutive operations by using
the appropriate SETUP commands. The last data previously
written to or read from a port is retrieved by using the PDATAOUT
command. The current state of the 1260-14C is determined by
using the PSETUP command. Refer to the individual syntax
descriptions for each command and the examples given later for
the specifics regarding these operations.
The outputs of the 1260-14C are connected to an external voltage
that provides inductive fly-back protection. If inductive loads are
to be driven, the external voltage must be supplied to the module.
Failure to do so may cause damage to the module's output stage.
If protection for inductive voltage fly-back is unnecessary, Vext does
not need to be supplied to the module.
The 1260-14C allows twelve separate external voltages to be
supplied to the module's front panel. These external voltages are
supplied to the output stages on a byte-by-byte basis. This allows
some flexibility as to the OC output voltages that are supported
simultaneously by the module (see the 1260-14C Block Diagram).
Also, the VXIbus supplied voltages (+5V, +12V, and +24V) are
used to pull up the output stage if the module is fitted with internal
resistive pull-ups.
The 1260-14C includes provisions for the installation of internal
pull-up resistors. This includes twelve 16-pin DIP sockets
designed to accommodate standard 16-pin, eight resistor-isolated
style DIP packages, such as CTS P/N 761-3-R10k or Bourns P/N
4116R-001-103. The 1260-14C contains no internal pull-up
resistors at time of shipment.
It is recommended that outputs be pulled-up with 10kΩresistors if
driving standard logic gates. Internal pull-ups are limited to a
minimum value of 10kΩdue to the amount of current available

User Manual 1260-14C
Module Specification 1-2
from the VXIbus supplies.
The output stage of the 1260-14C may sink up to 200mA. The
limitation to this is the power dissipation in the output stages of the
IC. (See Figure 1-3 for the maximum allowable package power
dissipation.) If many 200mA loads are to be driven, they should be
distributed across the module's outputs for improved thermal
management.
It should be noted that there is no tri-state capability on the 1260-
14C. Since the outputs are open collector, they are placed in a
pseudo tri-state by "driving" a 1 on the relevant channel. In this
way, the channels are controlled on a bit-by-bit basis rather than a
byte-by-byte basis as on the standard 1260-14.

Input/Output Open Collector*
All outputs have inductive-load transient suppression diodes built
in, and must be supplied with an external voltage source (V
ext
) for
this protection to be active.
CAUTION
Damage to the driver's output may occur if a highly
inductive load (i.e., relay coil drive) is driven without
an external voltage (Vext) being applied to the
module’s drive cells.
V
ext
may differ on a port-by-port basis, or can be jumpered across
all the drivers. The factory setting is to connect each port with its
corresponding Vext pin where Vext (1-12) are the user's input pins to
the drivers. The outputs may also be internally pulled up if fitted
with DIP resistor packs (this selection is also port- wide).
NOTE
Vext is limited to 1A per Vext pin used. For example,
the maximum current-carrying capability of a single
Vext pin is 1A.
* A CMOS-compatible and LS TTL versions of the 1260-14C are
also available.
