Overall Test Setup
3
Major Test Equipment

• 9 Personal Computers (PC), 2 IBM Thinkpad 760XD
  (from MIT), 5 running under Linux (from NCU??)
  and 2 running under Windows (from CSIST)
• 2 Ethernet Hubs
• 5 Power Supplies, 2 x 28V, 2 x 3.3V and 1 x 5V
• 4 55-pin feedthrough are used
• 3 24-pin feedthrough are used
• 1 optical fiber feedthrough is used

J-Crate Connections
5
Major Parts in J-Crate

• JBU no connection needed and memory test only
• AMSWire links
• CAN Buses
• 1553 Buses
• JLIF control
• HRDL/RS422
• JHIF control

6
J-Crate AMSWire Connections
7
J-Crate AMSWire Connections

• 6 backplane connections will run master/slave
  mode as they should be.
• 4 front panel connections will run 2 in master
  mode and 2 in slave mode.
• Cross connect front panel connections between two
  JMDC
• Total 8 cables are needed (1.5m)

8
CAN Bus Connections
9
CAN Bus Connections

• Three masters are running on the bus.
• Master JMDC will ping the other slaves.
• JPD control system will be used to operate JPD.
• CAN Test PC will get status from master JMDC and
  Dallas temperature data from two USCMs
  alternatively.
• Inside cable for J-Crate exists.
• Need an inside extension cable to JPD.
• Need an outside 60m cable to bring CAN buses to
  control room.

J-Crate 1553 Bus Connections
11
J-Crate 1553 Bus Connections

• Couples two ISS buses into the same bus. Only one
  has power at a time.
• Couple two STS buses into the same bus. They
  serve different RT address.
• Manually switch the ISS and STS buses under test.
• 4 60m bus cables
• 6 stub cables
• 6 2-branches bus couplers (or can be replaced by
  two single branch bus couplers with a short
  cable)
• 6 bus terminators
• All cables, couplers and terminators exist.

12
J-Crate HRDL/422 Connections
13
J-Crate HRDL/422 Connections

• Optical Fiber Feedthrough will be used for all
  four HRDL connections.
• Both HRDL channels are connected to test PC and
  will selected by software.
• Two RS422 connections will go to control room and
  will be manually switched during the test.
• All cables and adaptors exist. But Optical Fiber
  Feedthrough with all adaptors need to be checked.

14
Old Power Switch Box
15
Power Switch Box and Software

• Using old Power Switch Box to control JLIF and
  JHIF power.
• Control software can be used directly or modified
  special for new usage.

16
JLIF Control
17
JLIF Control

• Using relay to switch on either JLIF-Y interface
  or JLIF-Z interface.
• Switches to select RT address
• Using old JLIF port on Power Switch Box to
  control JLIF.
• Inside JLIF control cables need to be built.
• JLIF control box need to be modified.

18
JHIF Control
19
JHIF Control

• Using relay to control the power of JFOM-A and
  JFOM-B.
• Using 5V port of JFOM-A and JFOM-B on old Power
  Switch Box to control the relays.
• J422 is always powered. When we test HRDL, the
  RS422 cables should be disconnected. When we test
  RS422, both JFOM power should off.
• JHIF control box need to be built.
• Cables between Power Switch Box and JHIF Control
  Box need to be modified.

JT-Crate Trigger Connections

• Loopback AMSWire cables (0.5m) 10
• AMSWire cables from DetSim to Trigger (1.5m) 44

22
JT-Crate JINJ Connections
23
JT-Crate JINJ Connections

• Loopback AMSWire cables (0.5m) 52

24
JPD Connections
25
JPD Connections

• Dallas bus cable to J-Crate and JT-Crate need to
  be built.
• Extension cable for CAN buses need to be built.
