BLSERIES AC POWER SUPPLY
EIA-232 SERIAL INTERFACE SPECIFICATIONS
1.0 INTRODUCTION
The RS232 interface option for the BL series AC Power Supplies allows two way
communication with most computer systems. All programmable setup parameters may be
queried or modified via the RS232 interface using command syntax described below.
1.1
EIA-232 INTERFACE UTILIZATION
The RS232 interface may be connected to modems, controllers, computers, or any other
equipment capable of communicating with the RS232 protocol. It is assumed in the remainder
of this document that the RS232 interface is connected to a “host” computer.
The interface is configured to communicate with the following format:
Duplex: Full
Baud Rate: 9600
Bits: 8
Parity: None
# Stop Bits 1
Other BAUD rates, however, are available by special order
1.2 EIA-232 CONNECTIONS
SIGNAL AC SOURCE HOST
(DB-9) (DB-25)
GND 5 ---------------------------------------------------- 7
RXD 2 ---------------------------------------------------- 2
TXD 3 ---------------------------------------------------- 3
The RS232 interface does not currently support hardware handshaking.
