CONV-TTL-RS485 hardware project
This project presents the hardware for the CONV-TTL-RS485 system. Apart from linking to CERN EDMS, where the official production files for the CONV-TTL-RS485 system boards are stored, this project also contains the design files for extra cards used for testing.
The CONV-TTL-RS485 system is comprised of a front module board and a rear transition module (RTM) together with its piggyback.
Front module board
CONV-TTL-RTM-RS485-DB9 (RS485 I/O with D-sub9 connectors)

CONV-TTL-RS485 system boards
All previous releases of boards from this project can be found in EDMS versions. The most recent (final or under-development) versions of the boards are listed below:
-
Front module EDA-02541-V4-1
-
RTMs The front module can be fitted with one of these Rear Transition Modules RTMs
-
CONV-TTL-RTM-RS485-DB9 (RS485 I/O with D-sub9 connectors): EDA-02452-V3-5.
This RTM is composed of:- EDA-02452-V3-0 (motherboard)
- EDA-03712-V2-1 (D-sub9 daughterboard)
-
CONV-RS485-OPT-RTM (Optical I/O with ST connectors): EDA-03760-V1-1.
-
CONV-TTL-RS485-RTM (RS485 I/O with Lemo-2 pin connectors): EDA-02452-V3-1 (No longer supported).
This RTM is composed of:- EDA-02452-V3-0 (motherboard)
- EDA-02494-V2-0 (LEMO 2-pin daughterboard)
-
Note that the RTM motherboard (EDA-02452-V3-0) is common to the CONV-TTL-BLO.
Testing boards
The RS485 tester card was designed for testing both front module and RTM cards with a PTS test system.
