Handling the Module

ATTENTION:

This RS-232 module uses CMOS technology

, which is highly

sensitive to electrostatic dischar

ge (ESD). ESD may be present whenever you

are handling the module.

ake these precautions to guard against electrostatic damage:

•Avoid touching the interface connector pins on the RS-232 module.

•If the module is not in use, store it in the anti-static bag in which it was

shipped.

It is not necessary to wear an ESD wrist strap while handling the 1770-KFD

module.

Terminology

this term means

DeviceNet an open communication network designed to connect control

systems to plant floor devices, e.g., sensors, push buttons,

motor starters, and drives

DeviceNet is based on commercially available technology and

can be used by any company to develop interoperable

products.
