The BOP High Power switching power supplies support three communications protocols. The primary interface is the GPIB (IEEE 488.2).

The power supplies also support RS 232 at baud rates of 9.6 and 19.2 Kilo baud rates. The RS 232 supports both XON-XOFF and CTS/RTS protocols.

The RS 485, Kepco ’s single address, multiple instrument serial bus (IEEE 1118) allows the BOP High Power units to be configured in series and parallel configurations. Up to five units may be paralleled to quintuple output current and up to three units nay be connected in series to triple output voltage. Special configurations are also available for 2X2 (two parallel branches of two series-connected units) and 3X2 (two parallel branches of three series-connected units). The 2X2 configuration doubles both output voltage and current; the 3X2 configuration doubles output current and triples output voltage.

The GPIB and serial interfaces primarily use the SCPI language: (Standard Commands for Programmable Instruments). The BOP High Power units support the trigger system, including an external trigger input. They also support the LIST and Memory subsystems of the protocol. The SCPI interface is compatible with the BIT 4886 card and supports separate positive and negative limits.

CIIL language support is provided for compatibility with the Kepco MAT series and other MATE system instruments.

The GPIB interface also supports IEEE 488.2 commands, which start with he (*)character.
