System 2 Installation / Programming Manual

Printer

Corby’s optional security printer (p/n 4007) is UL listed, requires 110/120VAC, 60hz at 0.7A, and requires a

three prong grounded outlet. Cord length is five feet. Serial data to the printer is via RS232 data link. When

combined with a Video Display Terminal or PC, install the printer next to the VDT terminal with the supplied

data cable. The printer is factory set at 9600 baud.

You may use another make or model printer provided it conforms to the following specifications:

1. RS232C serial input.

2. ASCII character set.

3. Be able to receive data at 9600 baud.

4. Accept data format of 8 data bits, no parity and 1 stop bits.

Printer Wiring

The optional printer requires a three conductor, 22 or 24 gauge stranded wire, with an overall shield.

Maximum cable length from the System 2 to the printer is 100 ft.

Typical wire specifications are: Jacket thickness, .032 in. (81mm); insulation thickness, .010 in. (.25mm);

temperature rating, 80 degrees (C), UL style 1061, CSA type SR-PVC. Typical capacitance per ft. is 30 pf or

less.

Printer Ground

The foil shield of the printer must be earth grounded. Attach the shield from the printer cable only to Terminal

#1 of the System 2. DO NOT connect the shield at the printer.

Printer Connections

A cable needs to be made for this connection using a three conductor shielded cable. You will need a female

9 pin connector and a 25 pin "D" male computer connector. Use a good soldering iron, small tip, suitable for

electronic components. Do not connect the shield to the 25 pin "D" connector. (See Figure 9).

Using a three conductor, shielded wire, make the following connections:

9 Pin Connector (P1 - System 2) 25 Pin Male DB25 Connector (Printer):

Pin #5 Pin #7

Pin #3 Pin #3

Pin #8 Pin #20

Plug the 25 pin connector into the right side of the printer.

DO NOT make any connection to Pin #2 (RXD).
