7.5 Bypass Communication Wiring
iTDC/iTDC-SR will be able to communicate with Host PC when internal ECP/IP module is equipped. The
iTDC/iTDC-SR communicates RS422 with another iTDC/iTDC-SR.
First, you have to connect iTDC/iTDC-SR RS422 port to RS422 port of iTDC/iTDC-SR
(No.1 , TCP/IP communication) as below.
- Connect iTDC/iTDC-SR(No.1) controller
’
s RS422-TX(-) to iTDC/iTDC-SR controller
’
s RS422-RX(-)
- Connect iTDC/iTDC-SR(No.1) controller
’
s RS422-TX(+) to iTDC/iTDC-SR controller
’
s RS422-RX(+)
- Connect iTDC/iTDC-SR(No.1) controller
’
s RS422-RX(-) to iTDC/iTDC-SR controller
’
s RS422-TX(-)
- Connect iTDC/iTDC-SR(No.1) controller
’
s RS422-RX(+) to iTDC/iTDC-SR controller
’
s RS422-TX(+)
- Connect TCP/IP communication between iTDC/iTDC-SR and HOST PC.
- Install and run iTDC/iTDC-SR Application Software.

Second, you have to connect all RS422 port of iTDC/iTDC-SR in parallel except iTDC/iTDC-SR.
(No.1, TCP/IP communication).
- Connect RS422-TX(-) of iTDC/iTDC-SR to RS422-TX(-) of another iTDC/iTDC-SR.
- Connect RS422-TX(+) of iTDC/iTDC-SR to RS422-TX(+) of another iTDC/iTDC-SR.
- Connect RS422-RX(-) of iTDC/iTDC-SR to RS422-RX(-) of another iTDC/iTDC-SR.
- Connect RS422-RX(+) of iTDC/iTDC-SR to RS422-RX(+) of another iTDC/iTDC-SR.
