RELEASE DOCUMENT AB117
To provide information on the HPS-20XX Cluster controller.
OVERVIEW
This release document provides general information about howHPS2000 series cluster controllers work in conjunction with HPShost adapters.
The HPS2000 series cluster controller, referred to as Unplug II,is fully compatable with existing SYSTECH HPS host adaptors.
Cluster controllers are available in the following configuration:
HPS-2008 - Provides 8 x RS232C serial ports plus one parallel port.
HPS-2016 - Provides 16 x RS232C serial ports plus one
parallel port.
Up to 8 cluster controllers may be daisy chained via RG-62A/Vcoaxial cable, providing upto 256 serial devices, to an HPS hostadaptor board (DTC). Each cluster is assigned an exclusive addressby setting switches.
The serial ports are RS232C DTE data ports connected via RJ-45connectors.
The ports may be programmed individually for communication at baudrates of from 50 baud to 115K baud. Data rate, flow control, etccan be programmed from the host on a per channel basis.
INSTALLATION
The cluster controller, as previously mentioned, is fullycompatable with existing SYSTECH HPS host adaptors.
Therefore existing DTC/RTC installations using RG62A/V coaxialcable, BNC connectors, 'T' pieces and 93 ohm terminators aresuitable for use with the UNPLUG II.
New installations will follow existing DTC installation rules:-
VIZ:-
i) Maximum cable length is 1000 eg RG62A/V coax.
ii) Maximum number of clusters is 7 on a 1000' coax.
iii) Cluster controllers must be daisy chained together.
One end of the coax must connect directly to the host adaptor. Theother end must be terminated by a 93 ohm terminator.
Power Requirements:- Connect the HPS-20XX cluster controller viathe supplied lead and psu to an AC power source. This may be120VAC OR 220VAC. On power up the cluster controllers LED willblink as follows:-
Self-test - blinks quickly. This will be for 20 secs
Self-test complete - blinks a "heartbeat" pattern
i.e 2 blinks. Pause. 2 blinks. Pause etc.
This condition will remain until a host download has occurred.
Downloaded/Ready - blinks slowly at a rate of 1
blink per second. The cluster is now operational.
CONNECTING PERIPHERAL DEVICES
Connection to a terminal or other serial device will be via anRJ45 fly lead - terminated with a D type 25 pin female connector.This enables connection/use of existing cable specifications asper exisitng EDP RTC cable guidelines.
RJ45 fly lead specifications are included in this release documentand will be published in the EDP cable specs manual.
The flylead allows any current RTC cable spec to be used withoutproblem.
Parallel printers may be connected using an IBM pc compatableprinter cable.
Specifications are included in the release document and will bepublished in the EDP cable specs manual.

The above flylead will operate with existing cable specs for RTCto peripherals.
This includes ROE, UNIFAX, NDR ptrs etc.
CONFIGURATION
As with RTC's each cluster controller must be identified by aunique network node ID (address).
The HPS-20XX cluster controller offers flexibility to users ofprevious verisions of SYSTECH HPS cluster controllers. This isachievied by selectable emulation modes - native, 708X-030 or 7900series.
SWITCHES
The HPS-20XX cluster controllers switches are located on the unitsback panel:
ARCNET connection switch:
Located between the BNC connector and UTP connectors.
Set this towards the BNC connector.
OPERATING MODE SWITCH:
Labeled NORMAL and CFG.
NORMAL = operating mode.
CFG = configuration mode.
Setup:-
The HPS-20XX provides no visual indication of its node ID oremulation settings.
To VIEW or CHANGE any settings connect a terminal to the clustercontroller set up as 9600,8,no parity,1 stop bit on PORT 0.
Switch the operating mode switch to CFG.
Power on the cluster Current settings will be displayed after thePOST.
To change settings, answer y
Select the node ID as required OFF must NOT be used. This isreserved for the host adaptor.
After setting the node ID affix to the cluster controller numericlabels, supplied, to indicate is node ID.
Set the emulation as required by entering y to display emulationoptions.
708X-030 (old style RTC's)
7900 series (old style RTC's)
If you have selected one of the above emulations answer y toaccept downloads.
For new installations choose nature.
The new settings will be displayed and you will be asked if youwish to save these settings, to save press y.
Switch the OPERATING MODE switch back to NORMAL and press any keyto continue.
