The PRIM7 RS232/RS485 converter is an easy-to-use robust RS232/RS485 converter.\
\
It has been developed to work better in physically very large network, as encountered in high density metering sites,\
\
and very noisy environments, such as extremely high voltage substations.\
\
Some extra features have been added that are lacking in most other commercially available RS232/RS485 converters.\
\
\
\
Features\
\
\
\
The PRIM7 does not require any dipswitch settings, but will handle any baud rate up to 115200 baud automatically.\
\
The PRIM7 will work with any existing RS232 application software, as the direction of information flow to/from the RS485 network is handled automatically.\
\
Standard 2500Vrms isolation between the RS232 side and the RS485 side. 5000Vrms available as an option.\
\
Takes 220VAC directly, no need for an external power supply. 110VAC available as an option.\
\
The Prim7 also has the option of being powered from the communicating device, as a 10-16V supply is present on pin9 of the RS232 port.\
\
When this option is specified, a DC/DC converter is populated on the PRIM7 instead of the transformer.\
\
This option is only available with SDG recorders manufactured after 06/2004.\
\
Both male and female D-type connectors are provided.\
\
The male provides passive RS232 power on two pins, enabling the port to passively power a modem of the RAD SRM-6 family of short-haul modems.\
\
This enables RS485 networks separated by distances up to 22km to be interconnected into one RS485 network.\
\
Separate Rx and Tx LEDs are provided to simplify fault finding in the RS485 network.\
\
The PRIM7 can be mounted on either DIN-rail or G-rail.\
