Electrostatic discharge
The SDI cards meet the requirements of the IEC 801-2, clause 8.0
procedure. They can withstand a direct discharge of ±5 to ±20 kV without
being damaged.
Electromagnetic interference
The CS 1000E, CS 1000M, and Meridian 1systems meet the requirements
of FCC Part 15 and CSA C108.8 electromagnetic interference (EMI)
standards as a class "A" computing device. To accomplish this, the SDI
cables must exit the module through EMI filters on the I/O panel.
Reliability
The Mean Time Between Failure (MTBF) for all SDI cards is 55 years at
40¡C and 29 years at 55¡C.
Installation
To use a serial data interface card in a CS 1000E, CS 1000M, or Meridian
1system, first install the card in the system, and then configure the system
software to recognize it. These steps are discussed in the following
sections.
