SPC-MX/SX Series
Feature
Supports RS422 interface
This is a signal transmitter capable of transmitting multiple input and output signals using a small number of signal lines. A single main unit is capable of transmitting up to 32 input signals and 32 output signals. Up to three sub-units can be added, making it possible to extend the system to up to 128 inputs and 128 inputs, adding 32 inputs/outputs at a time. Wireless signal transfer is available using our free space optical communication. The device can transfer signals directly with computers or other devices with a serial interface.

|
|||||
|
b. DT (Data normal)
|
Comes ON when something is wrong such as corruption of data with the data received from other S/P converter.
When something is wrong with received data, this converter stays “OFF” before data is normal again. |

|
c. ALM
* 1. (Reception level alarm) |
Comes “OFF” when reception level of SOT to be connected lowers.
|
||||||
|
d. CDO
