HARDWARE HANDSHAKE
USING DTR SIGNAL
Figure 16-1. Event Log Printer Connections
The printer must be configured as follows:
7 data bits, even parity, 1 stop bit
300 or 1200 baud (1200 required if alpha numeric pager interface is installed)
Hardware handshaking using DTR signal
The 4100SM Module is supplied with a 10-foot RS232 cable. A longer cable or an extension
cable can be used if the VISTA-128B and serial printer are separated by more than 10 feet,
but the total cable length should be less than 50 feet.
The 4100SM Module must be connected to the panel using the distance of the trigger cable. The
wires
cannot
be lengthened to mount the module in a remote location.
Most printers either ignore the CTS, DSR, and CD signals, or require them to be high (i.e., 3-
15VDC as measured on RS232 DB25 Connector Pins 5, 6 & 8, respectively, with respect to
Ground Pin 7). The 4100SM Module sets these pins high. If the printer being used will not
operate with these pins high, then clip the blue (CTS), white (DSR), or red (CD) jumpers on
the 4100SM Module to set the corresponding signal floating. Important pins on the RS232C
cable are Pin 3 (data out), Pin 7 (ground) and Pin 20 (DTR - ready).
The DTR signal, as measured at 4100SM TB1, should be high (9.5-14VDC) when the printer
is powered, properly connected, on-line and ready to print. This signal will be low (0-
1.5VDC) when the printer is not powered, not properly connected, off-line or out of paper.
The VISTA-128B will not send printing data to the printer unless the DTR signal is high.
