2.3 Detailed Product Descriptions

2.3.1 QX751 Base

a. Features

The QX751 combines several desirable functions in one compact package. Each unit is a highly

integrated operator interface and controller with expandable I/O and networking capabilities have

standard features consisting of the following:

• Color Touch, resistive screen (TFT)

• 24 VDC powered

• RS-232 / RS-485 Serial Ports

• Integrated Bezel

• Real-Time Clock

• Flash Memory

• Removable Media memory for easy field upgrades

• System Key and Configurable Function Keys

• Ethernet (10/100 MHz)

• Back Pack Expansion Connectors (refer G required)

b. CsCAN Network

When used with a Back Pack option, the QX751 has the feature of CsCAN peer-to-peer

networking. (CsCAN is pronounced “see-scan”). CAN-based network hardware is used in the

controllers because of CAN’s automatic error detection, ease of configuration, low-cost of design

and implementation and ability to operate in harsh environments. Networking abilities are built-in

to the QX751 and require no external or additional modules.

Figure 2.3 – Pass Through Function (Available in CsCAN Networks Only)

The QX751 features the ability to pass through programming commands. When attached to an

QX751 serial port, a programming package (i.e. Cscape) can access other QX751 units or any

other QX/RCS unit connected to a CsCAN network by passing the programming command

through the serial port to the network port. One Cscape package (connected to one QX751 unit)

can program all QX751 or other QX/RCS units on the CsCAN network. When several QX751

models are networked together to achieve a specific purpose, the system acts like a large

parallel-processing controller.
