Communications Time
Regardless of whether SECS is used or not, take the time required for processing between the host
device and Amplifier Units into account when designing the system.
Communications time calculation formula (unit: ms)
READ: 156.3
×
(number of pages) + 3.8
WRITE, SAME WRITE: 381.9
×
(number of pages) + 160.1
BYTE WRITE: 385.4
×
(number of pages/8) + 277.2
TAT calculation formula (units: ms)
TAT = command and response transmission time + communications time
*The command and response transmission time differs depending on the network environment.
For example: Command and response transemission time is about from 10 to 40msec, when
connect between PC and the Amplifier Unit directly by the lan cable(100M).
