## DAQ/L3

**Currently VRC, SB, ETG emulated w/ capability of ~500 kByte/second.**

## Implementation December, 2000

**Four unique types of cards**
**Event Tag Generator (ETG)  (1)**
**Event Tag Generator Int. (ETGI) (4)**
**VBD Interface (VBDI) (8)**
**Serial Interface Board (SIB) (256)**
**SIB appeared in almost all components**
**VRC = VBDI + SIB  **
**SB = ETGI + 12 SIB**
**Node = Motherboard + 4 SIB**
**SIB design nearly complete but could not be routed according to design rules.  Too ambitious for form factor.**

## Implementation January 2001

**Response: **
**Simplify designs by building cards with functionality limited to specific site.**
**Short term:**
**Build a SIB1 or “SIBling” with functionality only required for VRC (to be used later in ETG)**
**Supplement this with increased ethernet capabilities. ~100Hz**
**Long term: **
**Stage upgrade by building SIB2 and SIB3 which are more specifically targeted to SB, L3Nodes, ETG and final VRC.**
**Current Status**
**SIB1 **
**At vendor, 20 bare boards to be shipped between Thursday and Tuesday**
**Assembled, at Brown 2/22**
**VBDi **
**At vendor today or tomorrow.**
**Assembled, at Brown 2/22**
**Designs of other cards well along, can be derived from work with original SIB**

## L3/DAQ Schedule

**Stage1 3/22 **
**50 Hz**
**VBDi/SIB at D0**
**Ethernet upgrade **
**>100 Hz**
**Still discussing implementation**
