WARNING/CAUTION
Do not connect both the load and the programming device return (com-
mon) to earth-ground potential. Otherwise, If the COMMON power con-
nection between the BOP and the load is lost, then the BOP can be
damaged by output current flowing inside the BOP along the program-
The safety features incorporated into the BOP to handle energy from Ac-
tive loads are unable to protect the power supply or the load if input pow-
er to the BOP is lost or if the BOP Malfunctions. It is recommended that
the user monitor “Power OK” flag pins 3 and 4 of the external Protect Port
(see Table 2-5) and implement a fast-acting means of disconnecting ca-
pacitive loads or crowbarring inductive loads to prevent damage to both
the BOP and the load in the event of input power loss.
For both parallel and series configurations, remove links between (COM
S) and (COM OUT) terminals of all slaves to prevent damage to the unit
and maintain system accuracy. Make sure to accurately follow Figures 2-
7 through 2-10 for proper connection of the units.

Before connecting a load, note that the unit is will power-up with the con-
figuration set by the power-up switches accessible through the top cover
(see Table 2-2 for switch settings). Verify that these power-up settings are
compatible with your load (see Figure 2-2 and Table 2-2 for switch set-
To change to change load type, baud rate or Trigger port Remote on/off
logic refer to PAR. 3.3.2.1; to change all other power-up settings listed be-
In addition to the power-up settings determined by the switches ac-
cessed through the top cover, many unit parameters may be saved for the
next power-up cycle using MEM:UPD commands (see PAR. B.12). When
using MEM:UPD, it is recommended that the unit be tagged with the cus-
tom power-up configuration to avoid unexpected behavior upon power-
DO NOT repeatedly toggle the circuit breaker/switch as this may damage
DO NOT repeatedly toggle the circuit breaker/switch as this may damage
If you are not sure what the saved settings are, disconnect the load be-
fore issuing *RCL. Then issue queries to identify the stored settings.
When the serial port has received an XOFF, the error message -400, QUE
error will be placed in the queue to indicate the loss of transmitted infor-
mation due to a received XOFF character. When XON is received, the unit
will transmit all data in it's buffer followed by the exclamation character
(!). This (!) character is not part of any message from the BOP and indi-
cates the transmission buffer has been cleared and the BOP is idle.
When using MEM:UPD it is recommended that the unit be tagged with the
saved configuration to avoid unexpected behavior upon power-up.
