Configuring Modbus/BSAP
Addresses can be entered in decimal or hex. AceManager will translate hex entries into decimal. The number before the “=” is ID, the number after is the IP address. There can be a total of 100 remote ID/Local addresses entered into the modem.
When using AT commands via telnet or direct serial connection, use ATMLIST for decimal IDs and ATMLISTX for hexidecimal. For example, if the ID is 27 and the IP is 123.123.123.124, you would enter it as ATMLIST27=123.123.123.124 or ATMLISTX1B=123.123.123.124.
4. Optional: Dynamic IP Address
If you do not have a static IP, the host modem should be configured to report its current IP to a Dynamic DNS (DDNS) server with IP Manager.
In the Host modem’s configuration, instead of IP address for the Addr List (ATMLIST or ATMLISTX), substitute a single unique name for each modem, i.e. remote1, remote2, etc.
When you configure IP Manager for the host modem, make note of your modem name and domain setting in AceManager in the menu selection Dynamic IP to be used with the remote modems.
Figure 8-4: AceManager: Dynamic IP
With names instead of IP addresses for the Address List, the host modem will query the DNS server for the current IP address assigned to the specific name of a remote modem to send a message corresponding to the ID.
When you use names instead of IP addresses, to ensure your modems are updated quickly with the correct IP addresses for the names, you will want to set the DNS settings as well. In AceManager, select DNS.
