Chart recorder can be connected with PC with RS232 or RS485. It is possible to send parameters values serially to chart recorder for printing or it is essential to connect all signals physically for printing?
It means instead of connecting thermocouple physically at channel No1. Can I send the value of thermocouples (mV) to chart recorder serially via PC for printing its value. If it is not possible then for what purpose serial interface can be utilized?I turn to you for most suitable quote of chartless recorder with complete model number I am thankful for all your help and assistance.
