【質(zhì)譜應(yīng)用方案】質(zhì)譜儀未建立通訊 No communications
未與 XEVO TQD、TQ-XS、TQ-S micro 和 SQD2 建立通訊 -
故障描述
無法在 MassLynx 的 Tune 頁面中控制 MS
與 MS 之間失去通訊
MassLynx 窗格（右下角）出現(xiàn)錯(cuò)誤信息 Instrument Not Present（儀器不存在）
環(huán)境
MassLynx 4.1
TQD
SQD
Xevo TQD
Xevo TQ-XS
Xevo TQ-S micro
SQD2
原因
質(zhì)譜嵌入式 PC (EPC) 未與主機(jī) PC 建立通訊。
解決方法
關(guān)閉 MassLynx 軟件和 MS 控制臺(tái)。
找到儀器前面的 EPC 的復(fù)位開關(guān)（位于電源和狀態(tài) LED 下方的小孔），或者檢查 TQD 中靠近電路和氣體連接的內(nèi)側(cè)前面板門。
將一截 PEEK 管或回形針插入步驟 2 提到的小孔中。此處即為 EPC 復(fù)位開關(guān)所在位置。
等待 3 分鐘，讓 EPC 運(yùn)行其啟動(dòng)序列。
打開 MassLynx 軟件，確認(rèn) MassLynx 窗格（右下角）顯示信息 Not Scanning（不掃描）。
打開 MS Tune 頁面，確認(rèn)真空讀數(shù)“真實(shí)”且所有儀器正常通訊。注意：如果 MS 已放空，請(qǐng)打開 Vacuum > Pump（真空 > 泵），啟動(dòng)初級(jí)泵。
在 MS Tune 頁面中，確認(rèn) MS API 氣體可以打開，MS 進(jìn)入 Operate（運(yùn)行）模式，并且有合理回讀。
附加信息
或者，如果上述軟復(fù)位無效，您可以嘗試以下方法。
重啟 PC 電源。
關(guān)閉 UPLC 機(jī)架上的所有模塊電源。
登錄 PC。
重新打開 MS 的電源（如果系統(tǒng)處于放空狀態(tài)）?；蛘吒鶕?jù)上述操作按 EPC 的復(fù)位開關(guān)（如果系統(tǒng)處于真空狀態(tài)）。
等待 5 分鐘進(jìn)行通訊。
通過在 Microsoft 命令窗口中檢查 Telnet EPC，驗(yàn)證與質(zhì)譜儀的通訊。
進(jìn)入 Masslynx。
No communications with the XEVO TQD, TQ-XS, TQ-S micro & SQD2 - WKB7610
Article number: 7610
SYMPTOMS
Unable to control MS in MassLynx tune page
Loss of comms with MS
"Instrument Not Present" error message in MassLynx pane (bottom right)
ENVIRONMENT
MassLynx 4.1
TQD
SQD
Xevo TQD
Xevo TQ-XS
Xevo TQ-S micro
SQD2
CAUSE
Embedded PC does not have communications with the host PC.?
FIX or WORKAROUND
Close MassLynx and the MS console.
Locate the EPC reboot switch on the front of the instrument (small hole just below the power and status LED) or for TQD check inside front panel door next to electrical and gas connections .
Push a piece of PEEK tubing or a paper clip into the small hole mentioned in step 2. This is where the EPC reboot switch is located.?
Wait three minutes for the EPC to run through its boot sequence.
Open MassLynx and confirm that?a "Not Scanning" message is in the MassLynx pane?(bottom right).
Open MS Tune page and confirm vacuum readings are "real" and that everything is communicating properly. Note: If the MS has vented, go to Vacuum > Pump to start the backing pump.
Within the MS tune page, confirm that MS API gas can be turned on, the MS into Operate mode and that there are sensible readbacks.
ADDITIONAL INFORMATION
Alternatively if the above soft reboot does not work you can try this.
Recycle?PC.
Shut all modules on the UPLC stack.
Login to PC.
Turned power back on to MS?(If the system is vented). Or press?the EPC reboot switch as described above if system is under vacuum.
Wait 5 minutes for comms.
Verified comms with Mass Spec by checking Telnet EPC in Microsoft command window.
Enter Masslynx.
