Comments: Attn: CEFD Customer
Thank you for your purchase of Comtech’s High Speed CDM-760 modem. Your modem
has been pre-loaded with two (2) firmware images.
Image 1: is FW version 1.6.3 and should be used if you are using the modem’s optional
Packet Processor. It is the default firmware the modem will boot with if you do nothing.
Image 2: is FW version 1.7.4 and can be used if the modem does not have a packet
processor installed. You may use Image 1) FW version 1.6.3 (default) if you choose,
but certain features such as support for ASI data interface and DVB-S2X MODCODs
will be unavailable unless you boot to image 2. It is not suggested to run Image 2 FW
version 1.7.4 with the packet processor enabled.
