4.3 Rear Panel
The rear panel contains the connections for the power supply, probe, bar code reader, external
computer keyboard and RS232 serial port as shown below. The bar code reader and external
computer keyboard share the same socket and are only available on the model 5100.
Power Supply Connection
The power supply connection requires a 4.5 to 5.5 VDC power supply with at least 350 mA
current (6.0 VDC 800 mA when using the YSI 5015 bar code reader).
Probe Connection
The connector for the probe is an 8-pin mini DIN connector and is marked with an arrow to show
proper alignment. Be sure to align the arrows when plugging in the probe.
YSI 5000 series probes, such as the YSI 5010 BOD probe, will plug directly into the 5000/5100.
If you have an older YSI 5700 or 5900 series probe, the YSI 5011 adapter will be required.
The YSI 5011 adapter has a mini-DIN connector at one end and a 5-pin MS connector and probe
power connector at the other end. The 8-pin mini-DIN connector plugs into the 5000/5100 probe
socket and the 5-pin MS connector plugs into a 5700 or 5900 series probe/cable. The power
connector plugs into the matching connector on a self stirring BOD probe. This allows the
5000/5100 to power the BOD probe, eliminating the need for a separate probe power supply.
NOTE: Do NOT plug the 5011 adapter power connector into the 5000/5100 power supply
socket. Doing so will prevent the 5000/5100 from operating.
