6 x 4 ELECTRONIC SCSI SWITCH

i. Report Temperature:

example command: <cr>//t<cr>

example report: //t+19.5 +19.5 = +19.5˚C, +67˚F

j. Report SCSI-Bus Performance: example command: <cr>//P<cr>

report format: //P<aabbccdd112233445566<cr>

For ports A through D and 1 through 6 respectively, aa through dd and 11 through 66 = ASCII representations of 8-bit hexadecimal values from 00 to FF, where 00 represents 0% busy (completely idle) and FF represents 100% busy

k. SCSI Bus Inactivity to SCSI Report: example command: <cr>//I<cr>

report format: 1111 2222 3333 4444 5555 6666

For ports 1 through 4 respectively, 1111 through 6666 = ASCII representations of 16-bit hexadecimal values that express the length of time in tenths of seconds that the port has been inactive (not transmitting or receiving data). For example, “0A73” = 0 x 4096 (163) + 10 x 256 (162) + 7 x 16 + 3 tenths of seconds = 267.5 seconds = 4 minutes

27.5seconds.

l. Yank on SCSI Reset line:

example command: <cr>//BD235Y<cr>

report: none

m. Enable/Disable Audible Alarm:

example command: <cr>//OAx<cr> [x = ASCII 1 or 0]

x:0 = enable alarm, 1 = disable alarm report: none

n.Set Serial-Port Baud Rate:

example command: <cr>//OBxy<cr> [x and y = ASCII 1 or 0]

x:0 = COM1, 1 = COM2

y:0 = 9600 bps, 1 = 19,200 bps report: none

o.Set Mode of Serial (Comm) Port for RS-232 Port 2: example command: <cr>//OCx<cr> [x = ASCII 1 or 0]

x:0 = use Port 2 for daisychaining, 1 = use Port 2 as a second serial port report: none

Note: This command has no effect if the LAN port is enabled, which disables RS-232 Port 2.
