This memorandum presents the current inventory of con1n1ands applicable to the Passive Seismic Experiment Package. This revision reflects changes in the initial functional mode of the equipment as it is delivered to the lunar surface. This initial operating mode is specified in the PSEP Preliminary Operations Plan (EA TM-38).

This revision constitutes the final is sue of this memorandum in an effort to

(a) provide clarification of certain commanded functions {notes 3 & 6), and

{b) correct errors

An asterisk (:;"'() identifies the lines changed from Revision A.

PSEP Command List 2 14 L:PA~G:E~====-----------= OF----.----~

DATE 25 April 1969

This memorandum presents the current inventory of commands applicable to the Passive Seismic Experiment Package. The initial issue has been revised in the following areas:

a, The annotation of the preset condition of certain commandable functions has been revised to reflect the initial Junctional mode defined in the PSEP preliminary operational plan (EATM-38).

b. The significance of the High Data Rate command (CD-31) in inhibiting all data output has been flagged.

c. The classification of the commands has been expanded to identify those commands which are not significant in the operation of PSEP in the following groups.

those which control power distribution functions which were in the ALSEP 2 central station but have been deleted from PSEP

thos.e which are assigned to control functions 1n experiments which are not provided

those which have not been assigned to either PSEP or ALSEP.

The titles and scope of the attached Tables I, II and III are unchanged from the initial issue of this n1emorandum. The following notes are relevant to the data in each table as referenced:

Note 1 Operational mode inherent in equipment at power turn-on

Note 2 Operational mode preset during flight preparation

Note 3 Will inhibit all data output at the end of the data frame during ~~

which the command is executed. This is not considered to be a functional command for PSEP, but is listed ·to record the reaction of the Data subsystem to this command.

Note 4 Will not alter functional mode (housekeeping status may change)

PSEP Command List ~PA:::c~r::..::3==~o:F..:UL. __

DATE 25 April 1969

~------------------

Note 5 Changes bit rate upon command execution

Note 6 If CD-31 is, for any reason, executed by PSEP the data stream may be re-established by execution of commands CD-32 or CD-35. I£ CD-32 is used, the resultant data rate will depend upon which of the commands CD-33 & CD-34 was last executed. If CD-35 is used the data rate will be "Normal''.

Note 7 Manual leveling sequence is as follows: Send CL-15 to change. auto to manual leveling mode, change direction, and speed by CL-10 and CL-11 as necessary, and then leveling operating by sending appropriate leveling motor commands, CL-6, CL-7, or CL-8. Leveling operation is terminated by retransmission of CL~6, CL-7, or CL-8.

Note 8 Sequence of commands is auto on 1 /auto off/manual on/manu;l off.
