POP25: Single Radio and Multiple "Batch of" Radios

Warning 'Batch' Programming:  should not be used to add or modify system names and types in the radio, in order for the Radio IDs to be retained in the target radios, the Conventional System (System Name and System Type) and the Trunking System (System Name) MUST match between the CPS’s currently loaded codeplug and the target radios.

If you experience difficulties accessing a radio's IP address during a POP25 operation, depending on your system's firewall you may need to manually add the Motorola CPS as an exception to the firewall's exception list.

Over-the-air programming can rely on TCP Data Retransmission attempts to help ensure successful POP25 operation in the face of network (voice) activity and other network latencies. On supported Windows operating systems, Motorola recommends setting the "TCPMaxDataRetransmissions" registry value to 5 or more.

• For Windows XP, please refer to the Microsoft Knowledge Base article at http://support.microsoft.com/kb/314053.

• For Windows Vista please refer to the White Paper "TCP / IP Registry Values for Microsoft Windows Vista and Windows Server 2008" located at: http://www.microsoft.com/en-us/download/details.aspx?id=9152

Changing TCP / IP registry values affects all applications that require TCP / IP services. In addition, improperly configuring or editing the registry could cause serious problems or performance degradation. For added protection, back up the registry before attempting to modify it.

For POP25 on Conventional Systems only: The Windows operating system (Windows 7 and Vista) uses MTUs (Maximum Transmission Units) to determine the maximum size of the largest data packet (including any encryption header) that can be transmitted over the underlying network layer. The MTU size of over-the-air data packets for Conventional POP25 must be no more than 512 bytes each; otherwise POP25 programming may fail.

To set the maximum MTU size allowed by your computer's operating system, perform the following steps:

1. Open a command-line window in administrator mode by clicking the Start Menu, then right-clicking on All Programs > Accessories > Command Prompt, and selecting Run as administrator.

2. Type the command netsh interface ipv4 set subinterface "Local Area Connection" mtu=512 store=persistent

3. To verify that the change to the MTU size has been successfully saved, type: netsh interface ipv4 show subinterfaces

Must Be In Range

1. MANDATORY:

1. For POP25 to be accomplished on an ASTRO 25 Trunking System, POP25 targeted in-the-field radios must be in active Trunking Communication with an in-the-field POP25-capable and Data-capable Trunking System, OR

2. For POP25 to be accomplished on an ASTRO Conventional System, POP25 targeted in-the-field radios must be in active Conventional Communication with an in-the-field POP25-capable and Data-capable Conventional System.

Must Be Pre-Programmed in POP25 targeted radios codeplug prior to these radios going out in-the-field:

2. MANDATORY:

1. The POP25 Enable field must be enabled on a radio's programmed Trunking System that will be in communication with the in-the-field Trunking System; See #1a above, OR

2. The POP25 Enable field must be enabled on a radio's programmed Conventional System that will be in communication with the in-the-field Conventional System; See #1b above.

3. OPTIONAL: Data Wide, POP25/Wireless Programming Page preferences related to an in-the-field radio receiving a CPS Read, Write or Clone include:

   • See POP25/Wireless Programming Reject Enable

   • See POP25/Wireless Programming Indications

   • See Auto Reset Enable (applies to Consolette models)

   • See POP25 Retransmission Timer

Must Be Programmed in the CPS's codeplug prior to "over-the-air" Reading, Writing, and Cloning of "in-the-field" radios:

4. MANDATORY:

• The POP25 Enable field must be enabled for the same Trunking System as mentioned just above in #1a and #2a. Therefore, the System ID must be the same for this source codeplug's "POP25 Enabled" Trunking System, the in-the-field Trunking System (see #1a), and in the Trunking System of the targeted radio (see #2a).

• For Conventional-only radios, the POP25 Enable field must be enabled for the same Conventional System as mentioned just above in #1b and #2b.

5. MANDATORY: An Advanced Key with OTAP / POP25 capability must be currently loaded in the CPS (see the Advanced Keys Administrator and the System Key Report).

6. MANDATORY: From the Ribbon (CPS menu bar) è Device Tab, the appropriate Communication Method field must be set as "POP25" in order for over-the-air communications to occur.
