RS485 TERM1 /RS485 TERM2
Enables/disables the onboard 120 Ω line termination resistors according to the standards; RS485
communication requires a proper line termination value (120 Ω assuming a CAT5 twisted pair cable is
used) resistors in both ends of the bus. If the M2M Control CX320 device is used as an endpoint, the
relevant jumper can be installed.
Ain 1 – Ain 4
These jumpers are used to select between current and voltage input measurement. A jumper installed
on the position C for the relevant analog output will source current between 0-20mA, while in
position V, it will source a voltage level between 0..10V.
Aout 1 – Aout 2
These jumpers are used to select between current and voltage output. With a jumper installed on the
relevant analog output, it will source a current between 0-20mA.
Din 1 – Din 4
These jumpers are used to select between standard digital input or S0 input. With a jumper installed
on position S (pin 1 and pin 2), it will act as S0 input, while position N will operate as digital input.
