1. 3 2 ARMING CHARACTER amp PORT SELECT CHARACTER The arming and port addressing code consists of two characters in the form arm addr where arm represents the arming character and addr represents the port select character The arming character initiates Switch Time and is immediately followed by the address character which assigns the port Any port can switch the port when the unit is in Switch Time unless disabled by SW T position 6 The arming and switching code is stripped by the Code Operated Switch The Arming character can pass as data in Graphics mode Page 19 of 27 Rev L 09 10 ARMING CHARACTER This character is user selected and entered via DIP switch SW A See chart in paragraph 2 2 6 The arming character may be set as the equivalent of an ASCII CTRL HEX or Decimal character For example the arming character may be any one of the following CTRL characters A B C D E When the 1 5 receives the arming character within the data stream it will enter an armed state known as Switch Time and the ST LED on the front panel will be illuminated PORT SELECT CHARACTER The port select character is the first character received after the arming character and determines which Subordinate Port will be selected the port select character can only be recognized as such by its position in the data stream With the PORT16 switch SW C position 8 set False Closed only the least significant four bits ar2. 209 736 0425 Toll Free 800 222 2810 27 27 Rev L 09 10
