6300 Rear Panel

In a high-RF environment, these wires should be short and should be run
through foil-shielded cable, with the shield connected to CHASSIS GROUND at
both ends.
6. Connect tally outputs (optional)
See the schematic on page 6-28.
The 6300 supports two hardware tally outputs, which are NPN open-collector
and operate with respect to pin 1 (common). Therefore, the voltage applied to
the load (such as a relay or opto-isolator) must be positive. You can use the 12
VDC source on pin 25 to drive the high side of the load, taking into account the
fact that the voltage on pin 25 is current limited by a 310  resistor.
The tally outputs are protected against reverse polarity.
To avoid damaging the 6300, limit the current into a tally output to 30 mA. DO
NOT connect a tally output directly to a low-impedance voltage source! The tally
outputs are not protected against this abuse and the output transistors are likely
to burn out. When driving a relay or other inductive load, connect a diode in re-
verse polarity across the relay coil to protect the driver transistors from reverse
voltage caused by inductive kickback.
Note that the tally outputs have no special RFI protection. Therefore, it is wise to
use shielded cable to make connections to them.
See step 21 on page 2-38 for instructions on programming the tally outputs.
7. Connect to a computer
You can connect to a computer via the 6300's serial connector or via an Ethernet
network. (See Networking on page 2-46.)
You can connect to a computer via the 5500's serial connector or via an Ethernet
network. (See Networking on page 2-46.)
Procedures and instructions for connecting to a PC are subject to development

[Note: The 6300's front panel is described starting on page 3-1.]
The Power Cord is detachable and is terminated in a "U-ground" plug (USA stan-
dard), or CEE7 / 7 plug (Continental Europe), as appropriate to your 6300's Model
Number.
