4.1.7 ALC connection settings

In addition to the common connection settings, ALC hosts require these additional settings:

Table 4-7 ALC Connection Settings

ALC options

Description

TLS security

See Table 4-2 TLS Descriptions for a description of the various options.

Character encoding

Choose ASCII, EBCDIC, or IPARS (default) as the code set.

Configuration file

Enter the configuration (CNF) file that associates configuration information appropriate for a specific host type.

Terminal address

Select whether you want to specify the terminal address or use the Terminal ID Manager.

  • Terminal address - Specify whether to use 2-byte or 4-byte addressing mode.

    Although a unique 5-byte address is required when you specify the terminal ID instead of using ID Manager, this option specifies how many bytes of the 5-byte terminal ID address are sent with each message for the purposes of multiplexing. If you specify 2-byte addressing mode, only the last 2 bytes of the ASCU (Agent Set Control Unit) cluster address (A1, A2) are sent. If you specify 4-byte addressing mode, the full ASCU cluster address (H1, H2, A1, A2) is sent.

    Specify the unique 5-byte terminal address for this session. The terminal address is made up of five 2-hex-digit values in this order: H1, H2, A1, A2, and TA (terminal address). This unique address is usually assigned by the network administrator.

  • Terminal ID Manager- Provides IDs to client applications at runtime. If you choose this option, there are additional configuration options to complete. See Terminal ID Manager Criteria for descriptions of those options.
