Serial Controllers
The VME-ISER12 is an intelligent VMEbus interface w/ 12 serial process
interfaces, and an additional RS-232 interface for connecting a terminal for
service & programming. The serial controller SAB 82538 controls 8 serial
interfaces, and the CPU 68360 controls 4 as well as the terminal interface via
the SCC.
Physical Interfaces
Opto-couplers and DC/DC converters electrically isolate the interfaces
& VMEbus potentials. Piggybacks locally realize the physical interfaces
RS-232, RS-422, RS-485, & TTY-passive. The standard option has RS-232
drivers in sockets connecting via the VMEbus connector P2.
Wiring
The board is double Europe format with 4 TE (1 slot) width. The
VMEbus connector P2 has 9 serial channels available. If needed, an additional
channel connects via a front panel 9-pin post connector. A second
DSUB-connector in the front panel is for the terminal interface (RS-232). The
TTL-signals of the serial channels connect to two 50-pin post connectors.
QUICC-Power On-Board
The CPU 68360 has a phase frequency of 33 MHz to control the local
units. Firmware is stored in the Flash-EPROM & updates via a service
interface in the front panel.
VMEbus Interface
The board’s standard option offers the data transfer options
SADO24 & SD16. Optionally, the board can also be equipped with an A32/D32
interface. esd electronics does not recommend this option when using the local
physical interface because the isolation distances become very narrow.
ESP360-Transition Modules
Two ESP360 type transition modules connect via two 50-pin post
connectors, & each offers the transition of 4 serial physical channels to
the physical interfaces RS-232, RS-422, and RS-485. Two additional channels can
operate as RS-232 and RS-422 interfaces connecting via six 15-pin
HD-DSUB-connectors in the 6 HE front panels. With 2 ESP modules, all 12 serial
channels of the VMEISER12 are accessible as e.g. RS-232- interfaces. In the
ESP360 modules, channel selection is via software, bridges in the connector, or
solder bridges, because the interface options for each channel are parallel. One
advantage of the ESP360 adapter boards is the large isolation distance of the
electrical isolation allowing voltages of up to 300 VDC/ 250 VAC.
LED Displays
Selecting a serial channel via keys and a 7-segment display allows
you to read the selected signals via LEDs directly at the front panel at 2 mm
test sockets. The power supply of the electrically isolated interfaces shows for
each channel via LEDs.
Firmware
There is a channel-oriented RAM interface available as firmware
for the local CPU. The VME-ISER12 communicates w/ the VMEbus master via the
local RAM. The RAM stores the commands & parameters that come from the
local CPU and buffers the serial data. This Shared-RAM interface allows easy implementation
into different master operating systems. There are drivers for most real-time
operating systems available.
