    Pub. 42004-392G ® 17 of 56 LE200-RM R ODEL OUNT ARTY XTENDER Contact Closure Inputs & Relay Outputs (I/0) Five independent contact closures can be transmitted across a pair of Line Extenders meaning that an active input contact on the local Line Extender results in the corresponding output relay contact energizing on the remote Line Extender.
  • Page 20: Data Links Between Line Extenders

    Pub. 42004-392G ® 18 of 56 LE200-RM R ODEL OUNT ARTY XTENDER Data Links between Line Extenders The LE200-RM is equipped with two different data link types for connecting to another Line Extender. The two data types are T1/E1 and Low Voltage Differential Signaling (LVDS). The type of data connection(s) required is determined by the system architecture.
  • Page 21: Configuring The Data Links

    Pub. 42004-392G ® 19 of 56 LE200-RM R ODEL OUNT ARTY XTENDER Configuring the Data Links The T1/E1 and LVDS data link parameters between Line Extenders must be configured using multiple DIP switch settings on the Main PCBA. The following sections describe each parameter and the switch settings.

    Pub. 42004-392G ® 20 of 56 LE200-RM R ODEL OUNT ARTY XTENDER T1/E1 Receiver Equalization Gain Limit This option allows the user to compensate for diminishing signal intensity over the data line by adjusting the sensitivity of the receiver. By setting the Receive Equalizer Gain Limit, very long copper lines can be utilized.
  • Page 23: T1/E1 Data Line Grounding

    Pub. 42004-392G ® 21 of 56 LE200-RM R ODEL OUNT ARTY XTENDER T1/E1 Data Line Grounding T1/E1 data line can be floating or grounded. When floating, neither conductor of the data line cable pair is connected to ground. Headers P20 and P21 control the grounding of the T1/E1 lines. Grounding the T1/E1 lines may reduce emissions if it becomes an installation concern.
