Troubleshooting

Common Problems and Solutions

I.Missing blocks of data on shared device and/or buffer Overflow error display occurs - serial only

A.Flow control is not set or wired properly

If your device uses X-on/X-off, ensure that the corresponding port is set for X-on/X-off. If you are using DTR you have a miswired cable, see Section IIA below.

II.Nothing happens when sending data

A.Improper cabling

See 'CABLING' section.

B.Protocol does not match

Protocol on serial units is the baud rate, parity type, number of stop bits, bit size of the characters (5, 6, 7, or 8), and the handshaking type (DTR or X-on/X- off). Protocol in your device must match the protocol in the unit. See 'CON- FIGURATION' section.

C.Printer or computer connected to wrong port.

Input ports are 1-8, output port is O. Ensure devices are connected to proper ports.

III.Garbled data received at shared device

A.Protocol does not match See Section ll B above.

B.Flow control

See Section IA above.

C.Wiring interference

This may occur on computers which are a long distance from the Caretaker Plus. See 'CABLING' section for information on cable routing.

IV. Computer locks up

A.Buffer is full

Place unit in flow control display mode. If the computer port's LED is lit, the buffer is full. The shared device must accept some data to empty the buffer and allow the unit to accept more data from the computer. This will unlock the computer.

B.Flow control improperly wired See Section IA above.
