Communications Setup

025-9416 39

enter “1-aaa-xxx-xxxx,,,,,0555”.

1-aaa-xxx-xxxx = paging terminal phone number; 1 + area code (aaa)

,,,,, = pauses to allow the paging terminal to prepare for overdialing

0555 = default ConsoleNumber

8. Alternately, if the ZLINK connection is local (computer or dumb terminal), indicate

the appropriate baud rate for serial communications and identify the connection is

local as “B#L”.

B = indicates the baud rate is to follow

# = the communications speed (any rate between 512 and 9600)

L = local connection

Example: For 4800 baud local communication enter “B4800L”.

9. Enter the Password for ZLINK access to the paging terminal. The password is a text

string, up to 9 characters in length. Spaces are allowed and the password is case-

sensitive.

I CAUTION

Write the password down in a safe place, in case it is forgotten. Do NOT

give the password to unauthorized personnel.

10. Enter the number of the computer’s Comm Port used to connect to the Model 640. 1-

4 are the allowed entries. If the communication port is a non-standard type, identify

the port as follows:

pBASEaaaIRQx

p = port # (5 -9 allowed)

aaa = base I/O address of the port

x = IRQ address to use (2 - 7 allowed, usually 3 or 4)

11. Once all the fields in the Comm window are properly entered, save the record and

exit to the MCU main menu by pressing <Esc>.

Note: If a remote connection (modem) to the paging terminal will be used, it is

recommended that a temporary local connection (usually with a laptop computer) be

made for installation diagnostics. Refer to “Local Serial Connection” on page 34 for

details.

12. Power up the Model 640 and let it complete its boot sequence (all lights have

extinguished except the READY light is on solid).

13. Select Comm, Zlink from the main menu. MCU attempts to make a connection with

the Model 640.
