Each SyriXus series controller is provided with a method of selecting
unit identification numbers and a baud rate. For proper operation,
each instrument must be set to a unique unit identification number
(refer to Section 3.2.1 "Controller Models"). It is also important that
each unit's baud rate is set to the same speed. The factory default
setting is 9600 baud. Baud rates of 1200 and 19200 are typical. Other
baud rates of 300, 1200, 2400, 4800, 9600, 19200, 38400, 57600, and
115200 are supported by the SyriXus series pumps, but are not part of
the Teledyne ISCO defined communications standard.
Electrical standards are RS-232-C; connector pin usage is outlined in
Table 8-1 "External Control Connector Serial Pin Connections". Char-
acters consist of 1 start bit, 8 data bits (low order first with 8
always set to zero), and 1 stop bit. There is no parity bit used. All char-
acters will be printable ASCII characters. Control characters (0-1FH)
are ignored except for carriage return (0DH).
The serial unit number and baud rate can be changed from the default
values through the MENU key. Select SERIAL under the menu and
adjust the values using the softkeys.
Connecting devices to energized circuits may cause personal
injury or property damage. Power must be removed from the
pump before connecting external devices.
