Data Communication Services; Assignment Of Data Ports To The Modems - ABB ETL600 Instruction Manual

ABB Switzerland Ltd
This is a general prerequisite for data communication with ETL600 and
is explained in section 5.3.1.2.
5.3.5.1.

Data Communication Services

When APLC & DPLC channels are set, point to Configuration /
Services... / Data Communication to select the quantity of required
V.11 & V.24 ports in Data ports . This selection will define what kind of
RF-Converter Module will be required: P4LT or P4LU.
For transmission of only one V.11 channel over DPLC channel, leave
DPLC channel multiplexing unchecked. To enable the DPLC
channel multiplexer that allows transmitting up to two V.11 channels
together with up to 6 V.24 channels over the DPLC channel, check
DPLC channel multiplexing .
Different V.24 ports can share one communication channel either on
NSK600 or on MOD600: checking V.24 port sharing enables this
functionality.
Select the number of required NSK600 modems per each enabled
APLC channel.

Assignment of Data Ports to the Modems

Point to Configuration / Data port to modem assignment...
assign all utilized port to a modem and to configure the corresponding
communication parameter.
When configuring data communication for an ETL600 link, both
terminals of the link require to have the same configurations for the
utilized modems, interfaces, protocols and data transfer rates to
operate.

1KHW001489-EN
The selection of the NSK600 modems also defines
the V.24 port interfaces that will be used for the
respective modem.
If NSK600 modems with data rates above 600 bps
are used, the allpass has to be configured in the
corresponding APLC channel (refer to tab Channel
settings under Configure system ).
NSK600 modems with data rates above 1200 bps
(DAPSK modems only) require an equalization of the
corresponding APLC channel (refer to instruction
"APLC Channel Equalization" in the annex of this
manual).
When configuring data communication for an
ETL600 link, both terminals of the link require to
have the same configurations for the utilized
modems, interfaces, protocols and data transfer
rates to operate.
