Printer Cables . There are two (2) types of cables used with printers.
The 48-0079 is used with the AM-47 Hand-Held Printer. The
48-0078 is used to connect with most other 25-pin female serial EIA
printers. The pin assignments of the male connector are:
2 = RCV
3 = XMIT
7 = GND
20 = Data Terminal Ready (+12V typical)
Figure 6-3 shows the connections for the AM-47 Hand-Held Printer.
See ¶7.39 for operating instructions for printing.
Line Connection Cables . The RJ-11 (modular) and three (3) Bantam
cables illustrated in Figures 3-4 and 3-5 are used for line connections.
Use these cables as required to connect the AM-48 to 2-wire or
4-wire lines. Figures 6-1 and 6-2 illustrate and define Modular and
Bantam line connections. Be sure to set Switch 10 (Figure 3-5) to the
appropriate position as indicated in the Figures.
