AFETY COMPLIANCE
S
EN 60950
Applicable testing is routinely performed as a condition of manufacturing on all units to
ensure compliance with safety requirements of EN60950.
This equipment meets the Safety of Information Technology Equipment specification as
defined in EN60950.
The equipment is rated for operation at +12 volts DC and -12 volts DC. It has a
maximum power consumption of 2.0 watts. The power supply current is, in all
circumstances, supplied by a single Comtech CDM-600 Modem.
QUIPMENT CONNECTION
E
The CIC-20 LVDS to HSSI Interface Converter is designed for operation ONLY with
Comtech CDM-600 modems. These modems supply DC operating current (electronically
fused and protected) and control signals for the correct functioning of this unit.
Connection to other manufacturer’s equipment could result in damage to the unit.
NVIRONMENTAL
E
The CIC-20 LVDS to HSSI Interface Converter must not be operated in an environment
where the unit is exposed to extremes of temperature outside the ambient range 0 to 500C,
precipitation, condensation, or humid atmospheres above 95% RH, altitudes (unpressurised) greater than 2000 meters, excessive dust or vibration, flammable gases,
corrosive or explosive atmospheres.
Operation in vehicles or other transportable installations which are equipped to provide a
stable environment is permitted. If such vehicles do not provide a stable environment,
safety of the equipment to EN60950 may not be guaranteed.

Chapter 1. INTRODUCTION
CIC-20
LVDS to HSSI
Interface Converter
While the CDM-600 modem is capable of data rates up to 20 Mbps, its many interfaces
do not include the HSSI format.
In order to accommodate the HSSI data formats and overhead, the CIC-20 converter
attaches to the rear of the modem at the 25-pin data connectors. No external power is
required and all settings are made on the CIC-20 using one switch.

Chapter 2. INSTALLATION
Perform the following procedural steps:
1
Power down the modem before installing the converter.
2
Remove the four screws, on the sides, and lift off the cover of the CIC-20.
3
The 25-pin female and male D-sub connectors includes four captive screws which can be
reached by removing the cover of the CIC-20.
4
Attach the CIC-20 to the CDM-600 modem by mating the two pair of 25-pin D-subs together,
then tighten the four captive screws.
5
Re-attach the cover and replace the four screws. The metal surfaces of the modem and CIC20 should be flush.

Chapter 4. OPERATION
4.1 MODEM CONFIGURATION
After applying power to the modem, the following configuration changes must be made
to the modem in order for it to operate with the CIC-20.
1
Program the transmit and receive data rates to what is desired for Tx and Rx.
2
Set the data interface type to LVDS. The modem itself operates in this electrical format while
the converter translates between LVDS and HSSI.
4.2 MODE SELECT
The dip switch (S2) selects the functionality of the control signals, CA and TA. It can be
accessed with a small screwdriver. The OFF (down) position is the default. Switch S1 is
not used.
