TH2512 RS232
2
Explanation of command
1. RN
Range command copies all t\ranges of TH2512/TH2512A.
R0 command makes the range auto, and RF command makes range hold.
The range of TH2512/TH2512A can be selected by R1～R9 command，meanwhile use
range hold.
After the instrument being turned on, TH2512/TH2512A restores to default value：R0.
2.SN
The command copies all test conditions on the front panel，as the table above：
After the instrument being turned on, TH2512/TH2512A restores to default value S0、
S3、 S4、 S6、 S9。
3.G
A letter command, inputting the command is the same as pressing single.
4.?
A letter command，after inputting the command, the instrument can send the test result
to PC.
Caution ：SP command sets the print function of RS232 as on，by doing so, user can
read the test result without sending ？command constantly.
Use 485 bus to control instrument：
User can control the instrument by sending the command to TH2512/TH2512A，the
command can be single or in group, the format is ：
The first byte is scale-of-sixteen 55H + the second byte is address code + command +
the last byte is scale-of-sixteen 0AH.
Example：if the site of instrument id 6，and the instrument needs conteolling
to range 200mΩ，fast test，send the scale-of sixteen data :
55H，06H, 52H, 32H, 53H, 31H, 0AH
Output data: (data format)：
The message format is ：
Format：AAH + address + “H=±dddddd uu” + 0AH
Where：H: Displays type indication.
If being ：P: means displaying %.
If being：R: means displaying R.
dddddd : Test data, as table below：
uu : unit.
