2.0 INSTALLATION

2.1 UNPACKING AND INSPECTION

In most cases the VX414C is individually sealed and packaged for shipment. Verify that there has

been no damage to the shipping container. If damage exists then the container should be retained

as it will provide evidence of carrier caused problems. Such problems should be reported to the

carrier immediately as well as to C&H. If there is no damage to the shipping container, carefully

remove the module from its box and anti static bag and inspect for any signs of physical damage.

If damage exists, report immediately to C&H.

2.2 HANDLING PRECAUTIONS

The VX414C contains components that are sensitive to electrostatic discharge. When handling

the module for any reason, do so at a static-controlled workstation, whenever possible. At a

minimum, avoid work areas that are potential static sources, such as carpeted areas. Avoid

unnecessary contact with the components on the module.

2.3 INSTALLATION

AAAA

AAAA

CAUTION: Read the entire User's Manual before proceeding with the

installation and application of power.

Set the module's logical address and configure all jumpers as described in 3.2. Insert the module

into the appropriate slot according to the desired priority. Apply power. If no obvious problems

exist, proceed to communicate with the module as outlined in Section 4.0 (Operating

Instructions).

2.4 PREPARATION FOR RESHIPMENT

If the module is to be shipped separately it should be enclosed in a suitable water and vapor proof

anti static bag. Heat seal or tape the bag to insure a moisture-proof closure. When sealing the

bag, keep trapped air volume to a minimum.

The shipping container should be a rigid box of sufficient size and strength to protect the

equipment from damage. If the module was received separately from a C&H system, then the

original module shipping container and packing material may be re-used if it is still in good

condition.

3.0 FUNCTIONAL DESCRIPTION

3.1 GENERAL

VX414C is a general purpose switching module that provides individual switches for controlling

external devices and routing general purpose signals. The module provides 16 channels of Form-

A relays and 48 channels of Form-C relays with external access via a front panel connector. Each

Form-A channel includes a SPST non-latching relay with the two contact terminals of each relay

brought out through the front panel connectors. Each Form-C channel includes a SPDT non-

latching relay with the three contact terminals (COM, NO, NC) of each relay brought out through

the front panel connectors.

A functional block diagram is shown in Figure 1.

3.1.1 VXI Interface

The VXI interface, consisting of the VXI connectors, address decode logic, control logic and data

buffer, provides the electrical and mechanical connections to the VXI backplane. It performs

address decoding and bus buffering functions.

3.1.2 Data Latches

Programming of the module is through direct register access. There are 64 independent relays on

the module which are controlled using the relay control registers. The relay control register

receives relay control data from the VXI interface and latches it into registers. Module reset

results in these registers being cleared to a low output.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

3.1.3 Relay Driver

The relay driver function receives relay control data from the data latch and provides relay coil

current control for energizing or de-energizing the relay. A logic high on the input of the relay

driver results in a low on its output, thus providing a current through the relay coil, which closes

the contact. Module reset results in the output of the relay driver at logic high, thus de-energizing

the relay and opening the contact.

3.1.4 Relay Status

This function reports the status of the control state of the relays. A read of the relay status

registers allows a verification of the programmed state of the relays.

3.1.5 Relay

The contacts of the relay are routed to corresponding pins on a connector on the front panel, and

are available by supplying a mating connector and wiring to an external requirement. The relay

contact closes when the relay has a sufficient current applied across its coil. The relay is in its

open state if no current is present on its coil, such as when the module is reset.

3.1.6 Connector

The front panel connectors allow the relay contacts to be connected to an external application. A

mating connector must be acquired and wired to the external application.

Artisan Technology Group - Quality Instrumentation ... Guaranteed | (888) 88-SOURCE | www.artisantg.com

3.2 HARDWARE CONFIGURATION

Logical Address The logical address has a range of 0 to 255. Any value, except 0 and 255

which are reserved for slot 0 controllers and dynamic addressing, is valid. However, care should

be taken not to set the logical address the same as another module in the system. The most

significant bit (MSB) has a weighted value of 128 when the switch is in the off (1) position. The

least significant bit has a weighted value of 1 when the switch is in the off (1) position. The sum

of the weighted values of all the switches in the off position is the module logical address. The

switch location is shown in Figure 2.

3.5 CONFIGURATION REGISTERS

There are several registers used to configure and control the VX414C. These registers are

divided into two groups: VXI Configuration and Relay Control/Status. All of the registers are

located within the A16 address space as shown in Table I. The base address of the registers is a

function of the Logical Address of the module.
