To can make up your own RJ-45 to conventional to RS-232 DB-9 female connecting cable using a
standard Ethernet cable with the one end cut off. The standard color codes are:
▪ Pin 2 / RxD (receive data) = Orange
▪ Pin 3 / TxD (transmit data) = White/Green
stripe
▪ Pin 5 / GND = White/Blue Stripe
For proper serial communication:
Tx on your host (laptop) must go to Rx on the
CIPer50
Tx on the CIPer50 must connect to Rx on your host
so your Wire PIN 2 <> PIN 3 and PIN 3 <> PIN 2.
At the RS-232 DB-9 female connection:
• Orange > DB-9 pin 3
• White/Green > DB-9 Pin 2
• White/Blue > DB-9 Pin 5
