Jumper Settings-3

The Print Server Card may be restored to factory default conditions by jumper (OP2). 
The function of OP2 is to reconfigure NVRAM. This is done when a unit is moved 
from one site to another and should be restored to as-new condition.

If the unit is powered up with a jumper in the FACT position on OP2, the board will 
go into a reset all parameters to Factory Default state. This will be indicated by the 
three quick green flashes followed by the alternating red and green indications (once 
per second rate). This special indicator sequence means that the NVRAM parameters 
have been reset to factory default values. Now turn off power and shift the OP2 
jumper (labeled CUST or OP2). The unit will operate normally when you turn the 
power on again.

The bus handshake signal may be altered to match with your printer controller. Nor-
mal handshake signal is WAIT- signal (OP3 set to pins 2 and 3). Check your printer 
manual to determine if your controller requires the alternate handshake signal ACK/
RDY-(OP3 set to pins 1 and 2).

On a Print Server Card with both 10BaseT and 10Base2 capability there are two 
jumpers that affect Ethernet operations: Automatic/Manual (JP4) and Manual Selec-
tion (JP3).

The Automatic/Manual jumper causes the Print Server Card to select Ethernet net-
work type automatically when in the AUTO position. In the MA position, the selec-
tion is covered by the Manual Selection jumper.

The Manual Select jumper allows the user to force the Print Server Card to operate 
from the indicated connector. Note that with the Manual-10BaseT connection, the 
card will operate 10BaseT without the support of the LINK connect signal.
