3.3/5V logic level UART — for embedded systems and modem integration.
MO-TTL is for teams that build their own hardware. It runs directly at 3.3 V and 5 V logic and plugs into your modem board's UART with a JST connector — no converter in between. For AMR modem manufacturers, R&D prototypes and embedded data-collection systems it offers maximum reliability with minimum parts. The optical head side is identical to the rest of the family: standard IEC alignment, strong magnetic ring.
Embedded integration, modem manufacturers, R&D prototyping.
All electricity, gas and water meters with an IEC 62056-21 (IEC 1107) optical port. DLMS/COSEM and mode-E switching are carried transparently. Compatible with the TEDAŞ MASS ecosystem.
