4.7 Applications for Interface 2

Depending on the application, Interface 2 must be parameterised as described here. For
each setting, pay attention to the appropriate information under Chapter 3.12, Md.S2
(page 72), particularly with regard to the EK260 power supply.

4.7.1 Modem with control signals (standard modem)

F
For connection see Chap. 5.5, page 105).
A commercially available modem is connected to the EK260.
Settings under the interface list (→ 3.12, page 71):
- Md.S2 = 2
or 7
- TypS2 = 1
- Bd.S2 = 19200
- Num.T = 2...9
or 1
- PIN = ...

4.7.2 Modem without control signals

F
For this application the EK260 needs external power supply.
F
For connection see Chap. 5.5.2, page 106).
A modem with RS232 interface is connected to the EK260; RS232 control lines such as
"Ring", "DCD" etc. are not connected.
Settings under the interface list (→ 3.12, page 71):
- Md.S2 = 3
or 5
or 15
- TypS2 = 1
- Bd.S2 = 19200 * 19200 Bd (without using the baud rate selection)
- Num.T = 2...9
or 1
- PIN = ...
* Normally, modems do not carry out any baud-rate selection so that with Md.S2 = "5" and
"15" the values under the addresses 02:708 (Bd.S2) and 02:709 must be the same.
For the special case of a modem with baud-rate selection the starting baud rate (e.g. 300
Bd) must be set under Bd.S2 (address 02:708) and the baud -rate identification (e.g.
19200 Bd) under the address 02:709.
The ex-works setting is: 02:708 = 19200 Bd and 02:709 = 19200 Bd.
