NOTES on SETUP and USE of DIGI PORTSERVER.

1. This is NOT a replacement for the manual `PortSever User's Guide', but is a guide to how a PortServer has been implemented at Cambridge during the INT upgrade WFC/autoguider integration tests.

2. IP info
   portserver1.ast.cam.ac.uk 131.111.69.251
   Set this on NIS+ server using host setup (with ethernet address) and the PortServer will do a rarp and identify itself.

3. RealPort distribution kit
   beta-release version 1.3.0 Distribution kit in /data/Delphi2/psb/digi/solrp130b

4. PortServer firmware version 3.4.10
   in cass26:/tftpboot/ps3410

5. PortServer configuration file
   stored in (via psconfig tohost cass26 psconfig) cass26:/tftpboot/psconfig

6. realport installation tips:
   1. PortServer must be alive during pkgadd
   2. set ports to be dev=host (dev=prn seems to work also).
   3. using the name doesn't seem to work; tell it the ip number.
   4. during pkgadd, it asks if the device names are right; swap the /dev/cua and /dev/term entries.

7. realport troubleshooting:
   during use, if PortServer goes off line, it hangs the realport connections. To fix, either reboot host, or,
   1. kill all processes with open realport lines;
   2. kill and resart the daemon (ncxd, but cut and paste the startup line from the bottom of /etc/rc2.d/S26realport).
   3. restart the application processes.

8. PortServer to Camac 3340 (or SparcStation serial port). The PortServer has 10 pin RJ45 connectors. The 3340 and the Sparc we think have the same connector and pinout, so an adapter plug is made up with 25-pin D on the front and 10-pin RJ45 socket on the back.

              Sparc/3340             RJ-45 Socket
              TxD    2 -------------- 6 RxD
              RxD    3 -------------- 5 TxD
              RTS    4 -------------- 8 CTS
              CTS    5 -------------- 3 RTS
              DSR    6 -------------- 9 DTR
              GND    7 -------------- 7 GND
              DTR   20 -------------- 2 DSR
   

   You can then complete the IPL link by plugging a standard, straight-through CAT-5 UTP cable from PortServer to adapter plug.
