1.0 Introduction

The 4U2SEE signs are designed to display text messages, graphics, numeric quantities and other

information.

This document explains the ASCII (American Standard Code for Information Interchange)

communication protocol utilized to communicate with 4U2SEE display boards manufactured by

Electro-Matic Products, Inc. with relevance given to Electro-Matic input devices.

The 4U2SEE display is manufactured in two styles:

1. Standard – this version is NOT discussed in this manual and does not support ADP protocol.

2. Enhanced – this version supports ADP protocol and all features detailed in this manual.

There are two (2) methods of communications associated with the 4U2SEE display boards, Serial

and Ethernet. The Standard version is limited to Serial communications, while the Enhanced version

allows both Serial and Ethernet.

2) The physical size of the display – width and height

3) The power setting – selection of on/off enabling or disabling

4)Thetimezonesetting–GreenwichMeanTime(GMT)

For proper operation of the 4U2SEE display board, a set of communication rules must be followed,

format.

Electro-Matic Products has set a restriction regarding the speed of the messages, graphics, numeric

or other information sent to the 4U2SEE display. The maximum updating data rate for inputted

memorandums is approximately two (2) seconds.

PLEASE NOTE:

1) If data is issued to the display at intervals quicker than the approximate two (2) seconds, the

display may not get updated.

2) To send messages to the 4U2SEE displays, the run sequence or play list may need to be edited

or cleared. To accomplish this via the Electro-Matic input devices, please refer to Appendix B:

Delete File Playlist or Sequence or to set or delete a current play list or run sequence please refer

to section 6.4.11-12.

3) The construction of run sequences or play lists can be referenced in section 6.4.11 and is on a

 rst-inrst-out(F.I.F.O.)format.
