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.

Control I/F
Input signal
a. CTL (Control)
OFF : Normal operation
ON : Transmission stop Sent data +SD “H”, -SD “L”
Transmission stop +TC “H”, -TC “L”
Parallel output All points OFF
RCV output OFF DT output OFF
b. TCD
(Transmission stop)
OFF : Normal operation
ON : Transmission stop
Sent data +SD “H”, -SD “L”
Transmission stop +TC “H”, -TC “L”
Receiving is in normal operation
*Effective at full-duplex only
c. M/S
(Switching between master and slave)
OFF : Master Priority on sending
ON : Slave Priority on receiving
* Effective at half-duplex only.
Input circuit
Identical specification with parallel I/F
Output signal
a. RCV
(Receiving synchronization)
Stays “ON” while receiving data from other S/P converter (Operation equal to CD signal of SOT)
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
* 1. (Reception)
Comes “ON” when reception level of SOT to be connected normal.
* 1. ALM and CDO output become effective when the connection of SOT-GS50/80/150 series.
Output circuit
