Setup

1. Set Modem Type to Netgear CM1000 in DOCSight settings.
2. Enter the modem username and password. The default username is commonly admin.
3. Keep the default modem URL http://192.168.100.1 unless your modem uses a different management address.
4. Use Test Connection before saving.

Channel Data Formats

CM1000 firmware variants expose channel data in more than one format. DOCSight supports both:

• Pipe-delimited JavaScript values in InitDsTableTagValue and InitUsTableTagValue.
• Server-rendered downstream, upstream, OFDM, and OFDMA tables when present.

The JavaScript values are validated before parsing. Empty, commented, or malformed data does not hide a valid table response. Fields that the modem does not report, including unavailable error counters, remain unavailable rather than appearing as measured zeroes.

Authentication Safety

When form login is required, DOCSight submits credentials only to the known login endpoint on the configured modem. Form-provided external targets and credential-bearing redirects are not followed.

Bridge Mode

Status: Untested, likely compatible while the modem management page remains reachable at 192.168.100.1.
