Plug-In 52-Way 5Mm Pitch Terminal Block; Connector Pinout - MTX M2M MTX-DIN Series User Manual

4.2 Plug-in 52-way 5mm pitch terminal block

4.2.1 Connector pinout

Every MTX-DIN modem has a 52-way terminal block where all the interface signals are available for
use by the user. There is a label in the device which explains the pinout of this connector, as you can
see in the following figure. Use it as a reference for the following sections
