Figure 8 - Determine Which Modem You Have
The LTC Plus wireline satellites use one of
three possible modems. There are two ways to
determine which modem you have:
1. Look at the sticker on the back of the
modem. Choices are:
• 89-7519
• 102-0104
• 102-8568

2. The 89-7519 modem has a serial port.
The 102-0104 / 102-8568 modems do
not.
