MEGATEC COMMUNICATION PROTOCOL
A. 概括: 本文件指定的高级-智能UPS的RS232C通讯协议。该协议提
供了以下功能：
1. 监视器充电状态。
早饭做法大全2. 监控电池的状态和条件。
3. 状态监测工具。
4. 为电脑提供电源开启和关闭的省电效用如期开关功能。
电脑将控制信息由<cr>随后查询交流。UPS将响应由<CR>或付诸行动的信息。
Computer will control information exchange by a query followed by
<cr>. UPS will respond with information followed by a <cr> or
acti on.

** For OFF LINE UPS**
Its purpo is to identify a short duration voltage g litc h
which cau OFF line UPS to go to Invter mode. If this o cc urs
input voltage will appear normal at query prior to glitch a nd
will still appear normal at next qu e ry.
The I/P fault voltage will hold glitch voltage till n e x t
query. After query, the I/P fault voltage will be same as I/P
voltage until next glitch o cc urs.
** For ON LINE UPS**
Its purpo is to identify a short duration utility f ail
which cau ON line UPS to go to battery mode. If this o cc urs
input voltage will appear normal at query prior to fail a nd
will still appear normal at next qu e ry.
The I/P fault voltage will hold utility fail voltage till
next query. After query, the I/P voltage will be same as I/P
voltage until next utility fail o cc urs.
d.输出电压: PPP.P
P is an integer number ranging form 0 to 9.
The unit is Vo lt.
e.O/P current : QQQ
如果这是宋史
QQQ is a percent of maximum current, not an absolute v al u e.
