Before operating the unit, ensure the conductor (gr een wire) is connected to the ground (earth) conductor of the power outlet. Do not use a two-conductor extension cord or a three-prong/two­conductor in the power cord.
Maintenance and calibration procedures sometimes call for operation of the unit with power applied and protective covers removed. Read the procedur es and heed warnings to avoid “live” circuit points.
Before operating this instrument:
1. Ensure the proper fuse is in place for the power source to operate.
2. 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.

Introduction
The 1260-43 is an ultra high-density matrix switch card. Each module consists of three 8x24 matrices, which are interconnected via a 10-lane buss. On-board configuration relays allow software control of the matrix conf iguration.
Multiple modules can be linked together via a front panel 10-lane buss to form larger matrices. This allows the user to construct very large Matrices.

An Option 01T is r equired to communicate with any set of switch cards. Provisions for an Option 01T is not provided for on the 1260-43. Another switch card must be in the system t hat has an Option 01T installed in order for t he 1260-43 to work.
The following features are included in the 1260-43
• Data-Driven embedded descriptor, allowing immediate use
with any Option­firmware revision level.
• Three 8x24 Matrices in a Single VXI Slot
• 10 Lane Matrix expansion Buss
• Programmable Load Terminations
• Link Multiple modules via the front panel
Each switch can handle current up to 2 Amps. The 1260-43 plug­in fits into a standard VXI chassis.

1. Remove the 1260-43 module and inspect it for damage. If any damage is apparent, inform the carrier immediately. Retain shipping carton and pack inspection.
2. Verify that the pieces in the packag e you received contain the correct 1260-43 module option and the 1260-43 Users Manual. Notify Customer Service if the module appears damaged in any way. Do not attempt to install a damaged module into a VXI chassis.

Module Configuration
module consists of three 8x24, single wire interconnected via a 10-lane buss. On-board configur ation relays allow software control of the matrix conf ig ur ation.
The 1260-43 is comprised of three boards, the 405237, 405249 and the 405250. T he main controller board ( 405249) interfaces to the VXI buss and thus has all the c ontrol logic for communicating with the buss. In addition the control board decodes the address ’s that select the relay read/write ports. The relay board (405237) contains 900 relays of which 450 relays are on top with another 450 relays on the bottom. The control board c onnects to the relay board via five 200 pin connectors. The connectors pass the relay
connect to the out side world. The interf ace board connects to the relay board using two 80-pin flex cables.
The interface board shifts the ‘Output Buss’ three positions t o the right before c onnect ing to J207. This is transparent to the user and is done so the 1260-43 is compliant with the IFTE specification when daisy-chaining two or more 1260-43’s together. This shift eliminates the need t o place the shift in the daisy-chaining cable. Thus the daisy-chaining cable becomes point-to-point.
If a 408006 (1260-43) is used, a 602780 cable is required in order to meet the IFTE specif icat ion.

Installation
To install the 1260­chassis, engage the printed circuit board into the grooves of the desired chassis slot. Slide the 1260-43 into the chassis until its connector mates with the connector on the chassis backplane. Push firmly to fully seat the connector. Tighten the two retaining screws at the top and bottom of t he 1260-43 plug-in.
A 01T is required in the system in order for the 1260­operate. An additional VXI Switch card containing a 01T needs to be installed in the system with the slot location to the left of the 1260-43.

output relay groups, each group of relays operating on the buss is operate on 5 of the 10 signals of the buss and thus have only one
control/status reg ister associated with each group. For the rest of the relay groups an A and B control/status reg ister pair is assigned to each group. Only bits 4-0 of the register are used. Bits 7-5 are not used and will display “111” when the status register is read. Register ‘A’ is assigned to buss signals 4-0 while register ‘B’ is assigned to buss signals 9-5.
The control registers are located in the VXI buss A24 Address Space. The A24 address for a contr ol r egister depends on:
1. The A24 Address Offset assigned t o the 1260-01T module by program is provided by the VXI buss slot-0 controller vendor.
The A24 Address Offset is placed into the “Offset Register” of the 1260-01T by the Resource Manager.
2. The <module address> of the 1260­value in the range 1 through 12.
3. Each control / status register on the 1260-43 has a unique address.
The base A24 address for the 1260-43 module may be calculated by:
(A24 Offset of Option-01T) + (1024 x Module Address of 1260-43).
The A24 address offset is usually expressed in hexadecimal. A typical value of 204000
is used in the examples that follow.
16
A 1260-43 with a module address of 6 would have the base A24 address computed as follows:
Base A24 Address of 1260-43 = 204000 = 205800
16
The control registers f or 1260-Series VXI modules are always on odd-numbered A24 addresses. The first two control registers for the 1260-43 reside at the firs t two odd-numbered A24 addresses for the module:
+ (40016 x 610)
16
(Base A24 Address of 1260-43) + 1 = Contr ol Reg . 0 (Base A24 Address of 1260-43) + 3 = Contr ol Reg . 1
So, for our example, the two control reg ist ers are located at:

Matrix Load Configuration
Each matrix has two loads that can be configured as a pull-up or pull­value and set it as a pull-up or pull-down. The two loads can be used in conjunction to form a pull-up/pull-down load.
Once configured, each load can be tied to one of the ten buss signals. This is accomplished using 10 relays, one f or each buss signal. Care should be taken that only one buss/load relay is activated at any one time. This assures that buss signals are not shorted together. Both loads can be t ied to the same buss signal to form a pull-up/pull-down load.
The following tables illustrate the activation of the corresponding relays to form pull-up or pull-down loads for each of the three matr designator of the r elay used while the ‘1’ or ‘0’ is the state of the relay activation bit written in the corresponding register.
