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/two­prong 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.

NOTE FOR SYSTEMS WITH 1260-OPT 01T

The “Module-Specific Syntax” section of this manual shows the command syntax for the
1260-01S Smart Card. If you are using the newer 1260-01T Smart Card, the commands
will NOT work as shown.

Consult the 1260-01T Manual for a description of the commands that may be used with the
1260-01T Smart Card.

The channel numbers described in this manual are valid for the 1260-01T. The channel
numbers continue to be used for the 1260-01T.

The syntax of the commands that use channel numbers has changed for those cards
controlled by the 1260-01T.

The new syntax used to close a channel is:

CLOSE (@ <module address> ( <channel> ) )

For example, for a relay module whose <module address> is set to 7, closing <channel> 0
is performed with the command:

CLOSE (@7 (0))

Using the older 1260-01S, the command would be (as shown in this manual):

CLOSE 7.0

Many other command syntax differences exist. Please consult chapter 2 of the 1260-01T
manual for a description of the commands that are available for the 1260-01T.

Amendment Page 6/98 1

Control Information for the 1260-35A

The 1260-35A operates as a 4-wire MUX. T hus, when a channel is operated, 2 relays must be operated in
parallel. For each channel, when a bit of Control Register X is set (or cleared), the same bit of Control
Register X+6 must also be set (or cleared).

Each channel on this module is theref ore controlled by setting or clearing two bits, one each in two different
Control Registers. Control Registers on the module operate 8 channels simultaneously. There are eight
control bits per Control Register. Setting the bit to a 1 closes the relay; setting the bit to a 0 opens the relay.

The table below shows the mapping between logical channels used to operate the relay module in m essage­based mode and the bits within the Control Registers which m ay be used to operate the channel in r egister­based mode.

Each Control Register is located 2 addresses from the previous Control Register. That is, each Control
Register is located at an odd address. This is shown in Table 2-2 of the 1260-01T manual. Control Register 0
is located at the “Base A24 Address” for the module. Consult the “Register-Based Operation” Section of
Chapter 2 of the 1260-01T manual for a description of calculating control register addresses

For example, when closing channel 13, both byte 1 and byte 7 must have bit 5 set.

Control Information for the 1260-35B

The following information describes the control-register-to-relay-channel mapping for a 1260-35B Relay
Module. This inform ation may be used to control a 1260-35B when using a 1260-01T in the register- based
mode of operation.

Each relay on this module is controlled by setting or clearing a single bit within a Control Register. Control
Registers on the module operate 8 channels simultaneously. There are eight control bits per Control Register.
Setting the bit to a 1 closes the relay; setting the bit to a 0 opens the relay.

The table below shows the mapping from logic al c hannels to contr ol bits . T he logic al c hannels are us ed when
operating the relay module in message-based m ode. T he control bits within the Control Register s are used to
operate the module in register-based mode.

Each Control Register is located 2 addresses from the previous Control Register. That is, each Control
Register is located at an odd address. This is shown in Table 2-2 of the 1260-01T manual. Control Register 0
is located at the “Base A24 Address” for the module. Consult the “Register-Based Operation” Section of
Chapter 2 of the 1260-01T manual for a description of calculating control register addresses.

Analog Bus

In most of the above configurations, the 1260-35 may be user
configured to access an analog bus (refer to Figure 3-1). The
analog bus allows internal expansion for the configuration of larger
scanner/multiplexers than the module may achieve alone, by
providing access to a common bus channel which may be daisy
chained to other modules via the front panel.

To connect the module to the analog bus, install jumpers W2A,
W2B, W20A, and W20B.

MODULE SPECIFIC SYNTAX

1260-35 Module
Specific Syntax

Syntax

The Module Specific Syntax for the 1260-35 is required in the use
of the OPEN and CLOSE commands. It will also appear in data
output by the Master in response to the PDATAOUT and PSETUP
commands.

The Module Specific Syntax for the 1260-35 Signal
Multiplexer/Scanner module is as follows:

OPEN <module address>.<channel>[;<module address>.
<channel>]

where <module address> is the switch card address.
<channel> is the relay to be closed to connect an input to
the output.

Note that Channels remain closed until opened by an OPEN
command, RESET command, VXI hard or soft reset, or power-off.

NOTE

The <module address> used here is NOT the VXIbus
defined logical address of the 1260 Series Master. It
is peculiar to the 1260 Series and describes the
switching module in relation to the Master. This
address corresponds to the binary value of the switch
setting of SW1 on the switching module PCB.

The range of values for <channel> is:

One-wire 00-96
Two-wire 00-95
Four-wire 00-47

The actual mapping of number to connector pins is given in Table
3-1. Figure 3-1 shows the physical location of the various
connector pins.

Module Specific Syntax 3-1

User Manual 1260-35

Example:

OPEN 3.02
This open command will open channel 2 on the module at switch

card address 3

CLOSE Command

PSETUP
Command

The Module Specific Syntax for the CLOSE command is the same
as for the OPEN command.

The PSETUP command causes the specified module setup to be
transmitted to the VXI Controller. The syntax used is:

PSETUP <module address>[;<module address>] [;<module
address>] where <module address> is the address.

The responses to the PSETUP command for the 1260-35
Multiplexer/Scanner is as follows:

1260-35: Two-wire
<module address>. 1260-35B, Two-wire Scanner/Multiplexer

Module
<module address>. BBM
<module address>.END

1260-35: Four-wire
<module address>. 1260-35A, Four-wire Scanner/Multiplexer

Module
<module address>. BBM
<module address>.END

PDATAOUT

Module Specific Syntax 3-2

The response to the PSETUP command consists of a header on
the first line. The header describes the model number followed by
an A or B designating four or two-wire, respectively. The next line
designates the setup mode for scanning which, by default, is
Break-Before-Make (BBM). The last line containing the "END"
characters denotes no more information to report.

The PDATAOUT command causes the specified module to
transmit the CLOSED state of the relays within the switching

User Manual 1260-35

Command

module to the 1260 Controller. The syntax used is:
PDATAOUT <module address>[.<module address>]

[;<module address>]…..
The responses to the PDATAOUT command is as follows:
1260-35: Two-wire
<module address>. 1260-3 SB Two-wire Scanner/Multiplexer

Module
<module address>. <channel>[,<channel>] [,<channel>]
<module address>.END

1260-35 Four-wire
<module address>. 1 260-35A Four-wire Scanner/Multiplexer

Module
<module address>. <channel>[,<channel>] [,<channel>]
<module address>.END

The response to the PDATAOUT command consists of a header
on the first line as with the PSETUP response. The next line
details the channels currently closed on the module and is blank
when no channels are closed. Again, the last line is denoted by the
"END" string of characters.

Operation In
Single-Wire Mode

The 1260-35 is delivered with all jumpers installed (refer to Table
2-1). In this configuration, the module is a 1 x 96 two-wire
multiplexer (refer to Figure 3-1).

Channel 97 is a single pole, double throw (SPDT) relay with its
common channel connected to J202, pin B2. The normally closed
(NC) contact is connected to the "LO" side of the two-wire
common bus, and the normally open (NO) contact is connected to
the "HI" side of the common bus.

The common output of channel 96 is the single channel of the 192
x 1 multiplexer, and the 96 HI and 96 LO connections make up the
192 channels. By closing the appropriate channel (0-95) and
opening or closing channel 96. a 192 x 1 multiplexer is achieved.

Example:

CLOSE 3.46
CLOSE 3.96

This would correct J202 pin B2 to J202 pin A4

Table 3-1, 1260-35 Channel Closure

channel interconnect for 1, 2 and 4-wire modes.

1-wire mode:

<channel> <channel> output <channel> input
(channel 96 open)
0 thru 95 always J202- B2 (see 2-wire mode channels 0-95
input pins b-side of channel)
(channel 96 closed)
0 thru 95 always J202- B2 (see 2-wire mode channels 0-95
input pins a-side of channel)

Thus, a one 1 x 191 1-wire mode is acheived.

2-wire mode:
