TERMINATION
SET THE SWITCHES ON UNIT 1 (FARTHEST FROM THE PC) FOR BIAS DISABLED (S1-1/S1-4 OFF) AND EOLR TERMINATION ENABLED (S1-2/S1-3 ON). ON UNIT 4
1
ENABLE THE RS-485 TERMINATOR AND LINE BIAS. (THIS IS BASED ON THE ASSUMPTION THAT UNITS 1 AND 4 ARE EXTREME OPPOSITE DEVICES WITH THE
LONGEST CABLE LENGTH BETWEEN THEM, NOT NECESSARILY THE DEVICES THAT ARE PHYSICALLY LOCATED THE FARTHEST APART.)
2
SET THE SWITCHES OF UNIT 2 (AND ANY OTHER IMMEDIATE UNITS) TO OFF.
3
NOTICE THAT THE DAT – AND DAT + CONNECTION MUST BE INVERTED AT UNIT 4. THIS IS REQUIRED SINCE THE RRIs FOLLOW THE I9000
STANDARD WHICH IS THE REVERSE OF THE INDUSTRY STANDARD.
NOTES:
A MAXIMUM OF FOUR RS-485 DEVICES MAY BE CONNECTED IN A MULTI-DROP CONFIGURATION, INCLUDING THE TERMINAL SERVER.
THE GROUND BETWEEN UNITS 1 (TB2-1), 2 (TB2-1), 3 (TB2-1) AND 4 (GND) ARE NOT NECESSARY IF A GROUND REFERENCE IS PROVIDED THROUGH OTHER MEANS. ONLY
ONE GROUND REFERENCE MUST BE USED TO PREVENT GROUND LOOPS.
IN THE CONFIGURATION SHOWN, THE I9000 CONTROL PANELS ONLY COMMUNICATE WITH THE EBI PC; THEY DO NOT COMMUNICATE OR SHARE INFORMATION
PEER-TO-PEER.
