CAL
Description
Runs internal calibration of class and power loads.
Command:
cal
Response:
printf(":p%d Autocal OK\r\n", port);
or
printf("!p%d Autocal FAIL\r\n", port);
CAP
Description
Controls the 10uF capacitor across the full-wave bridge. This represents
either a legacy capacitive signature or an AC load.
Command:
cap [on|off]
Response:
printf(":p%d cap %d\r\n", port, state);
state
= 1 or 0 for on and off respectively.
CLASS
Description
Sets the IEEE load class. See IEEE 802.3af specification.
Command:
cl[ass] [0|1|2|3|4][+|-|>|<]
Arguments:
+
margin up 5%
-
margin down 5%
>
margin up 10%
<
margin down 10%
Response:
printf(":p%d class %d%c\n", port, class, margin);
Example:
p7 cl 3+
Example response: :
p7 class 3+<CR><LF>
This sets port 9 IEEE "class" to 3 with a 5% margin up.
CONNECT
Description
Controls the relay that connects all power load circuitry to the UUT.
When connect is off, the full wave bridge is disconnected and the UUT
sees no power circuitry connected to the GbE magnetics' center taps.
Connect must be on for the UUT to see an IEEE 802.3af load.
Command:
conn[ect] [on|off]
Response:
printf(":p%d Connect Sig %d\n", port, state);
state
= 1 or 0 for on and off respectively.
