DEIMOS Electronics Manual - Signal Assignments

Sheet 1:
(Refer also to drawing EL-1266) Referring to the first column or TB-A, pin-1 is wired to pins 57 and 56 of connector J20. This is the large 57-pin CPC connector on the amp connector panel. It connects the logic 5 volts and ground from the terminal strips to be distributed to the stage connectors. J10 is connected to amplifier 'A' and J20 is connected to amplifier 'B'. In the 'TO' column, these signals are shown being wired to pins 11 and 20 of the stage connector J5. That is to say, the +5 volt line is wired from pin-1 of the terminal strip to pins 56 and 57 of the large connector on the amplifier panel and from that connector to pins 11 and 20 of connector J5 which in this case is the CCD Focus stage connector. This same scheme is used for terminal strip pins 1 through 8 for each of the various stages. Terminals 9, 10, 14 and 15 are wired through J20 to pin 9 of connectors J21 through J28 to supply 5 volt to the auxiliary stage encoders. (The numbering scheme as shown on this page seems out of order but J10 is associated with connectors J1 - J4 and J21 - J24, and J20 is associated with connectors J5 - J8 and J25 - J28.) The rest of the terminals do not connect to the amp connector panel. Terminals 19 and 20 are wired to the Opto-22 relay module panel's '+' connection. Terminal 13 is connected to J58 and J59 and supply the +5V to the Science Filterwheel pushbutton station. Lastly, pins 19 and 20 are wired to the Opto-22 relay panels.

Terminal board B ( TB-B), supplies ground connections to the various stages via the large connectors either J10 or J20 depending on the amplifier. The first two terminals provide grounds directly to the AMP-1140 ground tie point. These wires connect from the large CPC connector directly to the black screw terminals on the amplifier. The rest of the grounds are wired in a similar fashion as +5 volt lines. Terminals 3 - 18 supply four ground connections to each of the stage connector J1 - J8.

It connects the logic 5 volts and ground from the terminal strips to be distributed to the stage connectors. J30 is connected to amplifier 'A' and J40 is connected to amplifier 'B'. In the 'TO' column, these signals are shown being wired to pins 11 and 20 of the stage connector J15. That is to say, the +5 volt line is wired from pin-1 of the terminal strip to pins 56 and 57 of the large connector on the amplifier panel and from that connector to pins 11 and 20 of connector J15 which in this case is the Slitmask stage connector. This same scheme is used for terminal strip pins 1 through 8 for each of the various stages. Terminals 9, 10, 14 and 15 are wired through J40 to pin 9 of connectors J31 through J38 to supply 5 volt to the auxiliary stage encoders. (The numbering scheme as shown on this page seems out of order but J30 is associated with connectors J11 - J14 and J31 - J34, and J40 is associated with connectors J15 - J18 and J35 - J38.) The rest of the terminals do not connect to the amp connector panel. Terminals 18, 19 and 20 are wired to the Opto-22 relay module panel's '+' connection. Terminal 11 is connected to J57 pin 8 that supplies the +5V to the grating pushbutton station and terminal 43 of Opto22 panel 5 there it supplies +5V to the Slitmask Pushbutton panel. Terminal 12 is connected to J19 pin 14 that supplies the +5V to the abandoned connector for a manual paddle and terminal 47 of Opto22 panel 6 there it supplies +5V to the grating 'CLOSED' clamp 5 signal. Lastly, pin 13 is connected to J49 pin 13 and J56 pin 8 where it provides +5V for the Slitmask stage environment sensors and Slitmask pushbutton panel respectively.

Terminal board D ( TB-D), supplies ground connections to the various stages via the large connectors either J30 or J40 depending on the amplifier. The first two terminals provide grounds directly to the AMP-1140 ground tie point. These wires connect from the large CPC connector directly to the black screw terminals on the amplifier. The rest of the grounds are wired in a similar fashion as +5 volt lines. Terminals 3 - 18 supply four ground connections to each of the stage connector J11 - J18. Terminal 19 supplies ground the connection for the Slitmask environment sensors via J49-4 and to Opto22 panel 4. Terminal 20 connects to the logic power supply's negative terminal to the terminal strip and supplies ground the connection for the Slitmask environment sensors via J49-8. Terminal 21 supplies ground the connection for the Slitmask environment sensors via J49-2 and to Opto22 panel 5. Terminal 22 supplies ground the connection for the Slitmask environment sensors via J49-6 and to Opto22 panel 6.

This sheet details the AC power terminal strips. TB-E and TB-H are associated with Galil controller panel #1 and TB-F with Galil controller panel #2.

Terminal 1 of TBE is wired to the Calibration Lamp Interlock box where it is interrupted by a relay in the entrance hatch circuit. It removes the AC power from the calibration lamp power supplies when the hatch is open. Terminal 2 connects to Opto22 panel #1 at pin 1 where it is distributed to various functions (See EL-3034). Terminal 2 also provides the hot leg to the 24V servo motor power supply. Terminal 3 provides the hot leg to the 5V logic supply and is connected to the incoming AC power cord. Terminal 4 provides the neutral leg to the 5V logic supply and is connected to the incoming AC power cord. Terminal 5 provides the neutral leg to the 24V servo motor supply and to switched outlet AC3 by which the Galil controller controls the power to the SCSI-to-Fiber converter. Terminal 6 provides the neutral leg to the switched outlet AC4 by which the Galil controller controls the power to the AIA-to-SCSI converter and for the Flexure Compensation System's white LED. Terminal 7 provides the neutral leg to the Copper Argon #1 power supply via J52-18. Terminal 8 provides the neutral leg for the cooling fans. Terminal 9 provides the neutral leg to the Copper Argon #2 power supply via J52-20 and to the switched AC outlet AC2. Terminals 10, 11, and 12 are neutrals for the various calibration lamp power supplies.

On Galil control #2, terminal 1 of TBF supplies the hot leg to the AC bus on Opto22 panel #4 at pin 41. Terminal 2 is wired to the AC bus on Opto22 panel #4 at pin 1 and is the input point to the terminal strip hot leg. Terminal 3 supplies the hot leg to both the logic power supply and the servo motor power supply. Terminal 3 supplies the neutral leg to both the logic power supply and the servo motor power supply. Terminal 5 is the input point of teh AC neutral leg and also is wired to J43-10 where it provides a neutral to the grating clamp system. Terminals 6 through 12 provide the needed neutrals for the rest of the grating clamp system.

On Galil control #1, terminals 1, 2, and 3 of TBH supplies the AC wiring that connects to the input of the AC Controller box for the 'orange' circuit located on the barrel of the instrument. Terminals 4, 5, and 6 of TBH connect to the output of the AC Controller box back to TBE pins 1 and 5. Terminals 7 and 8 provide for the wiring of the AC kill input to the AC Controller box. Terminals 9 and 10 provide terminals to wire the sonalert to.
