5Serial Configura- tion

5.1Overview

E2’s Serial Configuration is the centralized location where all communication ports (COM ports) may be set up in the E2 controller. To support the increasing number of third-party devices that E2 can communicate with, E2 has the expanded flexibility of dynamic COM ports that will support different types of communication protocols to meet the specific needs of the user.

Previously, all COM ports were pre-defined to support a specific type of serial device. E2 now has five configu- rable COM ports that can communicate with different devices on the network.

5.2COM Ports

The Serial Connection Manager is located in General Setup under the Serial tab. To access Serial connections to set up the COM ports, press Alt + M, or from the E2 Main Menu:

1.- System Configuration

2.- System Information

3.- General Controller Info

4.C3: Serial tab

To begin, first select the COM port you wish to set up, choose the protocol, and set the baud rate.

The user associates the various hardware devices with the COM ports listed under the Serial tab. Five COM ports have user-configurable values such as baud rate and con- nection type settings.

Pre-Sets

COM1 is pre-set for serial connection. COM3 is pre- set with a modem-only connection type. The COM5 con- nection is a non-configurable E2 keyboard port.
