The ATE1 is a clip on/off DIN rail mount port which is designed to extend a BARTEC VODEC VX/AT switch to allow connection of up to four VAP01 public address microphone access units. The ATE1 comprises of a rugged DIN rail mount PCB carrier, field cable terminal assembly and on board switching matrix. An array of LED indicators provide the engineer with ATE1 operation status and DIL switches allow the engineer to enable or disable ATE1 features to meet specific applications.
Further ATE1 ports can be cascaded up to a maximum of four models, inter port connectivity is by plug in/out flat IDC ribbon cable enabling simple expansion with minimal hardware impact. The ATE1 is managed by an on board processing sub-system that determines access priority, emergency/routine speech preference and system alarm tone control. Connection to the ATE1 from the host VX/AT switch is by single 34 way IDC plug in/out ribbon cable assembly. Connection to other ATE1 ports (where more that four VAP01 microphones are required) is by identical 34 way IDC ribbon cable enabling simple expansion with minimal hardware impact. Power supply is derived from the VX/AT management switch which is stepped down to provide DC 6 V to supply the VAP01 access unit(s).
