4.8  External Input Signal Cable 
  4.8.1  Connection of External Input Signal Cable 
  To connect the external input signal cable, use the attached dummy connector 
[XM3A–3721 (plug type connector), XM2S–3711 (connector cover)].    Some system 
input signals (normal close contact) of this dummy connector are jumpered.   
Remove the jumpers, when necessary. 
A cable with its single side soldered to the connector (TSL3000E/TSL3100E: INPUT 
cable) is provided optionally.    Contact our after-sale service agent in your territory.
