sTGC low voltage software controls user manual:

Here is what is needed to communicate with the LV supplies:

 

130.199.61.28 = stgc-lv1.starp.bnl.gov

130.199.61.29 = stgc-lv2.starp.bnl.gov

 

• Open a client socket (TCP) to IP address and port number: (crate #1 port number 5001,  crate #2 port number 4002) 
• Message format: ASCII -> command  board_number  channel_number   (NOTE: all lower case)
• Messages are returned to client terminated with "!"
• syntax example -> read board 113, channel 1 -> "r  113  1"

 

There are 8x boards (slots counting from 1) in a crate with decimal address: 113, 114, 115, 116, 117, 118, 119, 120

Each board has 8 channels but only 7 of 8 are installed on each board.

NOTE: board 0 address 112 is never installed

 

Valid commands are:

Enable channel................................‘e’ ->      enable    (board and channel number required)

Read Voltage and Current..................‘r’ ->       read       (board and channel number required)

Query board for enabled channels.......‘q ’ ->    querry    (board number required)

Scan crate for installed boards............‘s’ ->      scan       (NOTE: no arguments required)

scan all board and bin temperatures....'t' ->     display temperatures (no arguments)

check interlock status........................'i' ->     interlock status (no arguments)

 

Example: turn on channel one of board 1:

Send ASCII command -> e 113 1

Example turn on all 7 channels of board 1:

Send ASCII command -> e 113 127    (NOTE: seven bits on)

 

Example: read channel 1 of board 1 Voltage and current:

Send ASCII command -> r 113 1

 

board return message ->

Bd 113 Ch 1 V 10.37 I 0.61

 

Example: Query board 1:

q 113  

 

Returns -> B 113 e 127

 

Example: scan

s

Returns ->
> In this example, I only have boards in slots 1 (113, h71) and 2 (114, h72) installed.

Board in slot 0 not found 0x70,-1,5

Board in slot 1 found 0x71,0,5

Board in slot 2 found 0x72,0,5

Board in slot 3 not found 0x73,-1,5

Board in slot 4 not found 0x74,-1,5

Board in slot 5 not found 0x75,-1,5

Board in slot 6 not found 0x76,-1,5

Board in slot 7 not found 0x70,-1,5

Board in slot 8 not found 0x78,-1,5
 

Ratings and Specifications:

Power Total:         200 W / 8 Channel Board

Current / channel: Maximum 2.5 A (30W)

Voltage Output:    6.0V to 13.0 V out

Ripple:               

0.5 % at full load ( Bandwidth > 20Mhz),
0.1% ripple (20MHz)

Regulation:          < 1.0 %
Output Impedance: 0.20 ohms
 

Over-Voltage Protection: TVS crowbar  > 13.0 V
Over-Current Protection: Output Fuse 2.0A

Form Factor: 6u PCIe board/ DEP power system crate

Recovery Time (transient stability): Output settles to within +/- 0.5% steady state with 10% or greater change in load current

Operating Temperature: (operating environment): 0 deg. C to 50 deg. C with negligible derating
50 deg. C to 60 deg. C PSU will de-rate ~ 5.0%

Temperature Coefficient: Output Voltage change ~ 0.03% / deg. C
 
Thermal Protection: Each 8 channel power board is monitored with a temperature sensor by the crate controller
The individual DC/DC modules will drop output Voltage if the regulators temperature exceeds 80 deg. C
