For the Codan HF products that support “data”, what kind of data is this? How fast is it transmitted?

Codan provides a range of data options for different applications, with capability for messaging, email and chat. The data rates are generally between 75 bps and 9,600 bps (not including data compression), depending on channel conditions and the modem option you have installed.

Codan’s robust low rate modem, available as a software option in Envoy and Sentry-H 6120-BM products provides data throughput up to 2,400 bps (uncompressed) or 6,000 bps (compressed), and is a highly cost effective option. Codan also provides full MIL-STD modem This provides data according to MIL-STD-188-110A & B, with rates up to 9,600 bps.

When used with an independent sideband capable radio, the rate can be up to 19,200 bps. All data capability will depend on channel conditions.

Do I need to update my HF radio’s firmware?

You don’t have to update your firmware, your radio will be fully operational without firmware updates. However, should Codan recommend a firmware update for any reason, the firmware upgrade can be easily completed using NSP / TPS software, or direct through USB stick (Envoy radio series). Firmware updates generally provide your radio with new capabilities, or may address software bug fixes.

How do I load a profile or key to my HF radio?

For 2110 Series Manpack radios, profiles are loaded using our NSP software, and a serial or USB to serial convertor cable to the transceiver. For Envoy, TPS software is used to create a profile. Profiles can then be loaded via USB cable, IP connection or via USB memory stick. Keys are loaded using either our KMS or KFS software on 2110 Series Manpack and Envoy HF transceivers. Keys can be loaded to Envoy and Sentry-H 6120-BM radios using a USB thumb drive and a USB host adaptor.

What are the default IP addresses used in the Envoy and Sentry-H 6120-BM?

There are several IPv4 addresses allocated to the Envoy transceiver.

Default IP Addresses are:

  • Desk Console:
  • Handset:
  • RF Unit:
  • Virtual Control Point:
  • USB Programming Port: (do not change).
