2.7 SIGNAL CABLING
For best performance, signal connections should be made with shielded, twisted pair cable. If the
signal wires are combined in the same cable with the power and remote enable wires, then they should
be separately shielded. The following cables are recommended for general use:

Signal outputs are connected from terminal strip (TB1) on the Combo Reader to the SIG and SIG BAR
inputs on the selected Interface. Wires should be stripped approximately 3/8 of an inch and tinned.
The SIG output from the Combo Reader (TB1-2) connects to the SIG input on the Interface. The SIG
output (TB1-1) connects to the SIG input on the Interface. If shielded cable (recommended) is used,
the shield should be connected on one end only. It is recommended to connect the shield to the Combo
Reader SHLD connection (TB1-3) and leave the other end floating. It is acceptable to connect the
shield to the Interface and leave it floating on the Combo Reader. Over short distances or in
environments that are free of electromagnetic noise the shield may be omitted.
DO NOT CONNECT THE SHIELD TO BOTH THE COMBO READER AND INTERFACE!
