ZENO

-3200 USER MANUAL

Coastal Environmental Systems (206) 682-6048

Page 120

The four ASCII characters whose decimal value range between 28 and 31, as

well as the NULL (ASCII decimal value 0, Ctrl-@) and DELETE (ASCII

value of 127) characters, are excluded from being used as the Passthrough

Mode Escape Character.

Coastal Environmental Systems recommends that the two best choices for

the Passthrough Mode Escape Character are the ASCII characters ESCAPE

or Ctrl-Z (ASCII decimal values of 26 and 27)

139

since these are the least

likely to be used by serial sensor communications.

Before you decide to use a printable or other non-printable ASCII character

as the Passthrough Mode Escape Character, make sure that the device being

communicated with in Passthrough Mode does NOT use the character by

reading the device's instruction manual.

6.10. REPEATER CAPABILITY

Any ZENO

-3200 can be set up as a repeater between a host and up to eight remote ZENO

-3200s. The

purpose of a repeater is to repeat CCSAIL messages from a host to remote ZENO

-3200s that

communicate over a radio link but do not have direct line-of-sight (LOS) to one another.

The full set of CCSAIL commands available to the ZENO

-3200 is NOT available through a repeater.

CCSAIL commands requiring an x-modem data transfer, or an unknown amount of data to be returned

(the CCSAIL “DB” command), or direct access to the ZENO

-3200 User Interface (CCSAIL “OPEN”

command), are NOT available through the repeater. All other CCSAIL commands are available.

140

To set up a ZENO

-3200 to be a repeater, go to the Repeater Menu that is accessible from the

Communications Menu.

The following is a listing of the Repeater Menu from a ZENO

-3200 that is NOT set up as a repeater.
