RT  CHASSIS  (1A16).  Continued


TM 11-5820-890-30-5 2-5. POWER SUPPLY (1A3).  Continued The power supply outputs are over-current protected. If an output is shorted to ground, the power supply will shut down. CAUTION The power supply will not be damaged if an output is shorted. However, other modules in the RT may  be  damaged  if  this  occurs.  Exercise  caution  when  troubleshooting  the  RT. The power supply will also shut down if 6 V dc is applied to pin E. This is used by the two-wire interface to turn the RT  off  during  remote  operation. The  other  modules  in  the  RT  use  the  output  voltages  as  listed  in  table  2-2. Table  2-2.  Power  Supply  Output  Destinations Voltage  (V  dc) Destinations  (module-pin) 6.75 1A1-A,   1A2-R,   1A4-8,   1A5-H,   1A6-X,   1A7-77,   1A8-P,   1A9-F,   1A10-J, 1A11-X,  1A12-47,  J1-KK,  J2-E 10.0 1A5-B,  1A6-T,  1A7-76,  1A8-Q,  1A9-C,  1A10-F,  1A11-F,  1A12-41 3.5 1A1-M,  1A9-B,  J2-D 60.0 1A1-Q, 1A11-R -10.0 1A5-D,   1A6-Z,   1A7-72,   1A8-O,   1A9-A,   1A10-H,   1A11-D,   1A12-57,   J2-A 2-6. RT CHASSIS (1A16). The  RT  chassis  includes  the  front  panel,  backplane  assembly  (parent  board),  and  frame.  The  controls  and connectors on the front panel are used to direct the operation of the RT. The keyboard and SIG displays provide feedback to the operator. The parent board has 15 sockets for the plug-in modules (1A1 through 1A15). It also has three connectors that mate with the front panel connectors. It provides most of the module interconnections. The  terminals  (E  fields)  are  used  as  solder  points  for  wires  and  the  flexible  circuits  that  interconnect  it  to  the system  and  COMSEC  connectors.  Figure  2-8  identifies  the  external  connectors. The  frame  provides  physical  support  for  the  modules.  The  covers  must  be  properly  installed  and  the  screws torqued   to   provide   the   required   environmental   protection. Two interlock switches are present on the RT chassis. They protect the TRANSEC variable. They are connected to the ECCM module at pin e through E73. If an RT cover is removed, the switches ground E73. This will cause the  ECCM  module  to  zeroize  the  TRANSEC  variable.  When  troubleshooting  an  RT  with  its  cover  removed,  the interlock  switch  levers  must  be  fully  extended  to  use  the  FH  mode. 2-10
