CHAPTER 5: Configuration and Operation

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<aabb1122><cr>

For ports A, B, 1, and 2 respectively, aa, bb, 11, and 22 = 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

For ports 1 and 2 respectively, 1111 and 2222 = 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 (16

) + 10 x 256 (16

) + 7 x 16 +

3 tenths of seconds = 267.5 seconds = 4 minutes 27.5 seconds.

l. Yank on SCSI Reset line:

example command: <cr>//|B2Y<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.
