Supporting Hardware and Software

For 1:1 applications the CDM-600 is supported by the CRS-150, a low-cost external
switch. For Hub applications, the CDM-600 is supported by a low-cost 1:N switch, the
CRS-300.
The CDM-600 is a companion product for the Comtech EF Data line of RF Transceivers.
The Modem incorporates an FSK serial link that can be activated on the Receive IF port
for the purpose of communicating with a Transceiver, if connected. In this manner, a user
may monitor, configure, and control the Transceiver, using the front panel display and
keypad of the Modem. The EDMAC channel may also be used to convey M&C data to a
Transceiver at the distant end of a satellite link, if it is connected to a CDM-600.
The CDM-600 is supported by Comtech EF Data's SatMac software, a Windows
based application that provides a 'point and click' interface for complete systems of
Comtech equipment, comprising Modems, Transceivers, and Redundancy Switches. For
more information, or to order a free demo disk, please contact the factory.

Compatibility

The CDM-600 is fully backwards-compatible with the Comtech EF Data CDM-500,
CDM-550, and CDM-550T modems. Being an Open Network Modem, the CDM-600 is
fully compatible with modems from other manufacturers that are compliant with the
IESS-308/309/310/314 specifications. Note, however, that IESS-315 (VSAT Turbo)
defines closed network operation, and this therefore requires modems from the same
manufacturer at both ends of the link.
Power-up instantly (in which case the frequency of the unit will drift until the
oven has reached its correct operating temperature),
OR:
Select a warm-up delay, where the unit will not become operational until the
oven has reached a temperature close to stabilization value.
Notes :
* The CDM-600 uses an intelligent algorithm that takes into account the internal
temperature of the unit, and the amount of time it has been powered down. In this
way, the unit does not wait for the full period (which can be as much as 200
seconds) if power is cycled over a short time.
* If the warm-up feature has been activated, the time-out period can be instantly
terminated by pressing the CLEAR key on the front panel.
