Table 2.3 - Technical specifications of the SY1527 mainframe: input and output signals
(refer to the figure in Appendix A)
VSEL:
Std. NIM/TTL; 00-type LEMO connector.
Function
: channel voltage selection.
ISEL:
Std. NIM/TTL; 00-type LEMO connector.
Function
: channel current selection.
RESET:
Std. NIM/TTL; 00-type LEMO connector.
Function
: RESET from the front panel. If the duration of the RESET
signal is > T
RCPU
=100÷200 ms, only the CPU is reset; if it is > T
RCH
=
T
RCPU
+ 900 ms, also the boards are reset and the channels turned
off. The Reset must be enabled via the RESET FLAG software
window.
KILL:
Std. NIM/TTL; 00-type LEMO connector.
Function
: KILL from the front panel: it turns all channels off.
ENABLE:
Std. NIM/TTL; 00-type LEMO connector.
Function
: remote enable.
INTERLOCK:
open/closed contact; 00-type LEMO connector.
Function
: INTERLOCK command: it turns all the channels off as it is
open/closed, according to the position of the relevant switch.
INPUTS
REMOTE IN:
+12 V, 50
mA max., electr. Insul.; tol.:-40%

combination (defined by the user) of OVC, UNV, OVV, TRIP.
OUTPUTS
REMOTE OUT:
+12 V level, referred to the crate ground; tolerance: -20%
÷
+20%; 00-
type LEMO connector.
Function
: remote power-on of the adjacent daisy-chained crate.
HVSYNC:
Bidirectional differential signal ; 2-pin LEMO connectors.
Function
: sync clock for the PWS Units ((RS485 Std., 1.25 MHz).
