Table 2-5 Format of Serial Data Transfer
Note 1: In Th2618B: resistance (R) & dissipation (D)
Note 2: In Th2775B: resistance (R) & quality factor (Q)
The control command of TH2810B serial interface is listed in Table 2-6
(computer TH2810B, in the fo
→
rm of ASCII code).
In the following table, each command can only be sent alone, and you are not
allowed to send more than two commands once. Each command starts with
{ and ends with }. Command with wrong format can’t change corresponding
function, and will be dealt with as invalid command by the instrument. It’s
