<Figure 1> is the screen where Com Port(COM1), Com Baud(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) are input in DEVICE part. Com Baud, Parity Bit, Data Bit, Stop Bit.

ASM 142 Helium Leak Detector communication driver read schedule

Read schedule setting parameters are as follows:

1) STATION – Don't care.

2) Read Command – Command = AA, AC, AC3, ACA, ACH, etc. (Refer to <Table 1>)

3) Read Start Address – Don't care.

4) Save Start Address for Communication Server – saving start address of Communication Server.

5) Read Size – Read Size is fixed with 1.

Read schedule example)

READ, 0, CY, 0, 0, 1,
READ, 0, HV, 0, 2, 1,
READ, 0, PE, 0, 4, 1,

<Table 1> is a description of read commands type and stored values of ASM 142 Helium Leak Detector communication driver.

<Table 2> is a description of each bit which is stored by 'ST' command.

ASM 142 Helium Leak Detector communication driver store the same data in WORD, DWORD, FLOAT, DOUBLE, STRING memory, but the data formats are different.

 If you click the icon  in protocol option part, you can see the dialogue box such as <Figure 2>. you can also set read schedule by using this part.

<Figure 2> Example of ASM 142 Helium Leak Detector Communication Driver’s Option dialogue box

You can set read schedule by using , ,  button and listbox of <Figure 2>.

<Figure 3> Example of ASM 142 Helium Leak Detector communication driver’s read schedule Add/Edit dialogue box

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> will be shown.

2. Write settings

You can control values of ASM 142 Helium Leak Detector by using write commands.

Bit write

Bit write and word write have the same setting parameters except output value(0 or 1).

Word write

Word write setting parameters are as follows:

1) PORT : Port no. (0 ~ 255)

2) STATION : Don't care.

3) ADDRESS : Don't care 

4) EXTRA 1 : AC, AE, AK, AS, CT, DE, RE, SU, SW, VE, VS, WA, XO. (Refer to <Table 3>)

5) EXTRA 2 : Don't care.

<Table 3> is a description of write commands and contents of ASM 142 Helium Leak Detector communication driver.

Write example 1)

PORT:0,  station:1, ADDRESS:0000, Extra1:SU, Extra : 0

The setting parameter shown above is an example of word write for Advanced mode Selection of ASM 142 Helium Leak Detector connected with 0 port.

Write example 2)

PORT:0,  station:0, ADDRESS:0000, Extra1:WA, Extra : 0

The setting parameter shown above is an example of word write to reset Warning of ASM 142 Helium Leak Detector connected with 0 port.

Block write

ASM 142 Helium Leak Detector communication driver doesn’t support ‘Block write’.

3. Communication Cable Connection of ASM 142 Helium Leak Detector

You can connect communication cable between ASM 142 Helium Leak Detector and computer in the following ways.

RS-232C Communication Cable Connection

Connect RS-232C serial socket of ASM 142 Helium Leak Detector and RS-232C cable.
