5.5. 3610/3612 I/OExtension Modules
Introduction
I/Oextension modules extend the I/Ocapabilities of Coaxlink cards having the I/O extension
feature. This topic describes two modules:
□ 3610 HD26F I/O Extension Module TTL-RS422
□ 3612 HD26F I/O Extension Module TTL-CMOS5V-RS422
NOTE
The 3610 and the 3612 I/Oextension modules are almost identical!
They differ only by the electrical specification of the single-ended outputs:
low-voltage 3.3 V TTL for 3610, 5 V CMOS for 3612.
These I/Oextension modules are printed circuit board assemblies including:
□ a PCbracket fitted with SubD connector and LED indicators.
□ a printed circuit board assembly implementing the I/Odrivers and receivers and a control
logic.
□ a 26-pin high-density flat cable for direct connection to the I/O extension connector of the
Coaxlink card.
