16. UTICOR Technology LP 5 ASCII Protocol Introduction The PMD 1100 1200 1205s come from the factory with UTICOR and ASCII protocol software in them The simple movement of a switch allows you to select either protocol If you are using a slave with ASCII protocol this section will be vitally important to you the user In this section we will discuss the different commands that can be used in the ASCII Slave their format and several examples With this protocol you will not need or be able to use a PMD master to control the slave display However any standard ASCII terminal can be used to manage the slave display Preparation of the Unit for ASCII Operation 79730 3 The unit is equipped with a RS 422A RS 485 port This is the port that will be used for reception of the ASCII commands to control the display You need only wire the unit s receive lines to the host s trans mit lines because the transmitter port on the slave is not used The slave is equipped with a RS 422 repeater port This port allows the slave to echo the information received by the RS 422A Serial Port Besides echoing the received information the repeater also provides a signal boost for it The slave units may be located 4000 feet 1200 meters from one another Each unit 1s assigned a two part unit address consisting of a group and a unit number The unit address is assigned to the unit with two DIP switches on the processor board of each unit The eight
