Motorola Capacity Max: SeQent Integration Requirements

By SeQent Product Support Last updated October 2, 2026

Short answer

SeQent's FPLNKCAPMAX sends text alarms to Motorola Solutions digital radios through a connection to a Capacity Max System Server (CMSS).

SeQent's FirstPAGE Link for CAPMAX (FPLNKCAPMAX) delivers text-based messages to Motorola Solutions digital radios through a connection to a Capacity Max System Server (CMSS).

1. Abbreviations & Definitions

Abbreviation	Definition
`FP`	FirstPAGE
`FPAM`	FirstPAGE Alarm Manager
`FPLNKCAPMAX`	FirstPAGE Link for CAPMAX
`CAPMAX`	Capacity Max
`CMSS`	Capacity Max System Server
`MNIS`	MOTOTRBO Network Interface Service

2. Environment Requirements

The following must be in place for FPLNKCAPMAX integration:

A VM or PC to host FPLNKCAPMAX and Motorola Solutions’ MNIS software.
A network connection between the VM/PC host and the CMSS Presence Server. See 5. Port Tables to prepare firewall rules (if required).
To be provided by the radio dealer:
- Motorola Solutions licenses for MNIS (applied in Radio Management).
- MNIS Data Gateway Configuration Utility (software installation).
- MNIS Data configuration (created in Radio Management):
  - Exported as a .gwcfgx file.
  - Applied to the MNIS installation on the target host VM/PC.

3. Information to Collect from the Radio Dealer

Item	Default / Notes
Gateway Tunnel IP address	Site-specific
TMS UDP port	`4007`
Remote MNIS Control Interface TCP port	`55000`
Data Gateway Radio ID	SeQent default `65535`. This is the unique ID to be configured for MNIS.
Presence Server IP address	Include the IP address for the alternate CMSS if applicable.
Presence Server port	`50015`. Include the port for the alternate CMSS if applicable.

4. Software Installation and Validation

Install Motorola Solutions MNIS software.
Install SeQent FPLNKCAPMAX software.
Create and export the MNIS configuration in .gwcfgx format using Radio Management.
Open the MNIS Data Gateway Configuration Utility.
1. Select Configuration and choose Import. Select the MNIS configuration exported from Radio Management and press Open.
2. Select Configuration and choose Select Active Configuration. Select the desired MNIS configuration file and press OK.
3. Stop the MNIS service and restart it.
Ping a radio to validate MNIS functionality.
1. Select the ID of a radio that is in a known On state.
2. Use a tool such as https://www.browserling.com/tools/dec-to-ip to convert the radio ID from a decimal value to an IP value, then change the first octet from 0 to 12. Example: Radio ID 1234 > 0.0.4.210 > 12.0.4.210.
3. In a CMD window, ping the resulting IP. Example: ping 12.0.4.210
In FPLNKCAPMAX, configure the CAPMAX tab using the information provided by the radio dealer when performing the “New Server” step.
In FPLNKCAPMAX, create an SNPP User and set a username and password.
In FPLNKCAPMAX, create Talk Groups (if required).
In FPLNKCAPMAX, select a radio listed as Present in the Radio Status node and right-click to send a test message.
Test radio presence by turning the radio off, refreshing Radio Status in FPLNKCAPMAX, then turning the radio back on and doing the same.

Note: A successful persistent ping (step 5) confirms that the MNIS configuration and networking are working.
