A&D Journal Printer AD-8118A - Manual (Page 10)

Using the Optional Interface
The Serial input can be connected with a RS-232C input or current loop
input using an RS-232C optional interface. This can be done with the FX,
FY, FR, FV, FW and AD-4316 or AD-4321. (If the option is provided with a
current loop output, it can be used as well.)
Note that these units^are equipped with outputs that can be connected to
the AD-8917, AD-8918, AD-8117 and AD-8118A externally.

3 Ser. m+ Serial input + (TxD) /
4 GND Signal ground 1 J
5 Ser.lN- Serial input - (SG)

O The Serial Input is commonly used for the RS-232C and the current
loop. On a RS-232C connection, pin No. 5 Is used as the signal
ground; connect the shield to pin No. 2.
O Signal lines using a twist-pair shielded cable should work better. This
